Wireless underfloor heating control strip

The AURATON Floor Heating Controller is an 8-zone, wireless underfloor heating control strip designed to work with AURATON Vela actuators, a central heating pump, and a heating device. Individual heating zones are controlled using wireless temperature controllers from the AURATON Smart series.

Action

The AURATON Floor Heating Controller supports 8 separate heating zones and can also perform the following functions:

• control of the central heating circulation pump,
• controlling the central heating furnace via a relay with potential-free contacts,
• cooperation with the AURATON Pulse control unit to automate the AURATON Floor Heating Controller with other AURATON Smart series devices
• testing the signal strength between individual paired devices

Device operating modes

The AURATON Floor Heating Controller set together with the AURATON Smart series regulator can operate in two modes:

Mode I (local):
In this mode, the strip and thermostat can operate independently without the need for an AURATON Pulse internet control unit. The Smart series controller must be correctly assigned to the AURATON Floor Heating Controller. Only one Smart series controller can be assigned to each heating zone.

Mode II (remote):
In remote mode, the AURATON Pulse internet control unit can be used, providing access to the entire system from outside the home.
This allows remote heating control, event notifications, scheduling, and much more.

Control of the central heating pump and relay

The central heating pump or furnace is activated when heating is activated in any of the heating zones – the central heating pump operation indicator light will illuminate.
The central heating pump or relay is deactivated when no heating zone is active – the central heating pump operation indicator light will be off.
To improve the operation of the heating system, the AURATON Floor Heating Controller is equipped with a time delay system for switching on the central heating pump.
When the heating is turned on, the actuators are first activated, and then, after a 3-minute delay, the central heating pump and relay are activated. The waiting time for the pump and relay to be activated is indicated by the pump indicator light flashing. After this time, the pump and relay are activated, and the indicator light remains lit.
This action of the AURATON Floor Heating Controller is designed to rationally manage the heating and prevent excessive load on the central heating pump, which could lead to premature wear.

Information and comments

• Only one controller can be paired to each zone. The controller, via an independent channel, transmits two parameters to the AURATON Floor Heating Controller:
  – current temperature,
  – setpoint temperature.

Device pairing

For the AURATON Floor Heating Controller to operate correctly, it must be paired with a Smart series controller or the AURATON Pulse internet control unit. Pairing mode is indicated on the controller by a flashing green LED above the LINK button. A maximum of one controller can be added to a single heating zone.

Enabling pairing – AURATON Floor Heating Controller (pairing heating zones)

1. Press the appropriate zone button for 3 seconds, wait for a single beep, then release the button. When the zone enters pairing mode, the zone's indicator light flashes (0.5s/0.5s).
NOTE:
If a zone already has two devices assigned, you won't be able to select it. To add a new device to it, you must first unpair the previous devices.
2. After entering pairing mode for one zone, you can also enter other zones by briefly pressing the button for another zone. This allows you to pair the same controller to more than one zone simultaneously. Briefly pressing the button for a zone that was already in pairing mode deactivates pairing mode for that zone. Disabling pairing mode for all zones causes the AURATON Floor Heating Controller to return to normal operation mode. Confirm zones and initiate communication between devices by briefly pressing the LINK button.
NOTE!
Pairing mode is automatically turned off 60 seconds after the last zone has entered pairing mode or after the controller has been successfully paired or after briefly pressing the DEL button.
3. To pair the AURATON Smart series controller to a zone (or several zones), activate the pairing mode in the desired zones, briefly press the LINK button, and then start pairing in the controller (the description of pairing AURATON wireless controllers is below).
4. Successful pairing of the controller is confirmed by a single 1-second acoustic signal. Once the wireless device is paired, the AURATON Floor Heating Controller enters normal operation mode.

Enabling pairing – AURATON Floor Heating Controller (pairing the Auraton Pulse control unit)

Press the LINK button for 3 seconds, wait for a single beep, then release the button. The control unit's pairing status is indicated by the LED next to the LINK button flashing (0.5s/0.5s). The heating zone LEDs remain off. Within 30 seconds, start the pairing process on the AURATON Pulse control unit as well.

Copying paired controllers

The AURATON Floor Heating Controller also allows you to copy a previously paired controller to another heating zone without the need to pair the device again. To do this, follow these steps:

1. Press the button for the already paired zone for 7 seconds. You will hear a single pairing beep, followed by a double pairing beep. When you hear a triple beep, release the button. The zone entering the copying mode is signaled by a slow flashing of the corresponding zone's indicator light (2s/2s).
2. After entering copy mode for one zone, you can also enter other zones by briefly pressing the button for another zone. This allows you to simultaneously copy the same controller to more than one zone. Briefly pressing the button for a zone that was already in copy mode disables copy mode for that zone. Disabling copy mode for all zones causes the AURATON Floor Heating Controller to return to normal operation mode. Confirm the copied zones by briefly pressing the LINK button.

Enabling steaming – Heat Monitor controller

On the AURATON Heat Monitor controller, press thebd orcd for 3 seconds until the transmission symbol (W ) lights up on the display. The AURATON Heat Monitor controller waits 30 seconds for pairing. After this time, it will automatically return to normal operation.

Enabling pairing – AURATON Pulse control panel

Pairing in AURATON Pulse is enabled using the AURATON Smart App. After launching the app, press the green plus button in the center of the screen. When the next screen appears, tap the house icon labeled "Devices." On the next screen, name the device you're adding. After entering the name, press the "Add" button. Once successfully paired, you can place the device in any previously added room and add it to your favorites.

Evaporation of wireless controllers from the zone

Pairing a wireless controller from a single channel

1. If you know the zone to which the device was paired, press the button for that zone for more than 5 seconds. After 3 seconds, you'll hear a single pairing beep – do not release the button. After another 2 seconds, you'll hear a double beep, and the zone automatically enters unpairing mode (the indicator light flashes faster).
2. After selecting the regulators to be paired, confirm the operation with the DEL . After successful pairing, you will hear a single beep.

4. If all indicator lights stop flashing rapidly, the AURATON Floor Heating Controller will switch to normal operation.

Factory reset (unpair all devices)

After turning off the AURATON Floor Heating Controller using the power switch, press and hold the Del Del button ).

Evaporation of the AURATON Pulse control unit

To pair the AURATON Pulse control unit, hold down the Del until you hear a double beep. Once the control unit is paired, you will hear a longer beep.

TEST function

The TEST button is used to launch an additional "submenu" with separate signaling and the option to check the radio signal level. This mode is activated by pressing the "TEST" button. It automatically deactivates 5 seconds after the last button press.

Checking the steam status of the heating zones:

After activating TEST mode, you can check which zones are connected to other AURATON Smart controllers. If the LED next to a given zone is lit, it means it is paired. If the LED above the LINK button is lit, it means the system is connected to the AURATON Pulse control unit.

Heating/cooling mode:

In TEST mode, the central heating pump status LED indicates heating (LED on) or cooling (LED off). To change the mode, press and hold the DEL button for 3 seconds (while in test mode). Confirmation of the change will be signaled by a single beep, and the LED will change to the opposite state.

Signal level test:

1. We enter test mode
2. Next, to check the signal level of the AURATON Smart series controller assigned to a given zone, briefly press the button above the zone. For the AURATON Pulse internet control unit, press the LINK button.
3. If the device has correctly received the radio signal within the last 45 minutes, the LEDs next to the heating zones will light up – the more of them, the stronger the signal.
4. If there is no communication, the LEDs will be off and you will hear a long beep.

Working with an external temperature sensor

The AURATON Floor Heating Controller has a connector for an external temperature sensor operating in the safety system.

When an external sensor is connected, the operating temperature limit for the AURATON Floor Heating Controller without the AURATON Pulse control unit is 55°C. This means that if the system temperature exceeds 55°C, the AURATON Floor Heating Controller will turn off all heating zones and the furnace. This protects against excessive temperatures in the heating system. If the AURATON Floor Heating Controller is to operate without this protection, the sensor should not be installed.

Temperature sensor installation:
Mount the sensor on an exposed pipe near the manifold system.

Device functions

How does the heating function work?

The AURATON Floor Heating Controller activates outputs to eight heating zones, which are controlled based on the current and setpoint temperatures from other SMART sensors. If the current temperature for a given zone is lower than its setpoint temperature by at least 0.1°C, the output for that zone will be activated, activating the connected actuator. After a 3-minute delay to allow the actuators to fully open, the furnace
and pump will also be activated.

When all zones are turned off, the furnace is turned off first (it must be on for at least 1 minute – FurnaceGuard function), and then, 1.5 minutes after the furnace, the pump is turned off.

PumpGuard function

The AURATON Floor Heating Controller is equipped with a special "PumpGuard" function that protects the pump from possible stagnation. This function activates when the pump output has been inactive for at least 14 days. It then activates for 1 minute.

FurnaceGuard function

The AURATON Floor Heating Controller is equipped with a special "FurnaceGuard" function that protects the furnace from being switched on too frequently. Once the furnace output is switched on, it can be switched off after 1 minute of operation.

Overheating protection

Using an external temperature sensor, we can set the maximum operating temperature. For more information, see "Operating with an External Temperature Sensor."

Cooling mode

In cooling mode, heating zones are switched on using reverse logic. When the current temperature is higher than the setpoint temperature, the appropriate zone is switched on. Then, after 3 minutes, the pump output is activated (the furnace output remains off). The cooling mode setting is described in the "TEST" button functions.

Signal level

You can check the signal level for each device with which the AURATON Floor Heating Controller is paired. For more information, see the "TEST Function" section.

Function to restore the previous software

To restore the previous software version, set the power switch to "0" (device off), press and hold the "TEST" button, and then turn the switch to "1" (device on). The LED next to heating zone 1 should flash green. Release the "TEST" button when the LED stops flashing and remains green. After restarting the controller, the previous software version will be restored (in the event of malfunctions after the update). The entire process can take up to a minute, and the device must remain powered on during this time. The previous software version is always loaded. If the software was previously updated from version 1.6 to 1.5, the previous software version is 1.6.

Cooperation with the AURATON Pulse headquarters

The AURATON Floor Heating Controller is paired with the AURATON Pulse control unit just like with other devices (as described in the section on pairing devices). The only difference is that pairing mode is activated on the control unit through the app by pressing the green plus sign at the bottom of the screen and then clicking the "Devices" icon. Details are described in the app's user manual. The photos below show the main view with all AURATON Floor Heating Controller channels, the internal view of the heating zone (channels 1-8), the internal view for pump control (channel 9), and the internal view for furnace control (channel 10).

• 

• 

• 

• 

• 

• 

In each of the available zone channels we can see the current temperature and set the set temperature.

In the pump output control screen, we can manually turn on the output, view the temperature of the external sensor and set the protection for the maximum operating temperature (if the sensor is connected).

In the furnace output control screen we can manually turn the furnace on or off.

Cooperation with other devices via the AURATON Pulse control unit

Classic setting – AURATON Heat Monitor

1. Actuators
2. Central heating pump
3. A heating device, e.g. a gas furnace
4. External temperature sensor

In classic underfloor heating, all that's needed for proper operation is an Auraton Pulse control unit paired with an AURATON Floor Heating Controller and several AURATON Heat Monitors (ideally, one for each room). AURATON Vela actuators are connected to the appropriate heating zones, and the pump and furnace are connected to the connector on the AURATON Floor Heating Controller.

• 

For the system to function properly, the current temperatures of the appropriate Smart series controller must be grouped with the current temperatures of the AURATON Floor Heating Controller. The same applies to target temperatures if you want to control them from the controller's front panel.

Mixed system – underfloor heating, radiator – AURATON Heat Monitor, AURATON Radiator Controller

1. AURATON Floor Heating Controller
2. AURATON Heat Monitor.
3. AURATON Radiator Controller
4. Heater
5. A heating device, e.g. a gas furnace

In a mixed system, where most rooms have underfloor heating installed, but there is also a radiator in addition to the Heat Monitor, we can also pair the AURATON Radiator Controller to the control unit and mount it on the radiator.

• 

• 

To turn on the furnace (or furnace and pump) output not only when any of the AURATON Floor Heating Controller's heating zones is active, but also when the thermostatic head (AURATON Radiator Controller) on the radiator commands heating. To do this, add the "Heating" function, select the appropriate thermostatic head channel in the Controllers tab, and set the AURATON Floor Heating Controller's furnace (or furnace and pump) channel as the actuator.

Remote control of the furnace and/or pump – AURATON Heater Controller

If in our heating system we do not have the possibility to directly connect the output of the furnace and/or pump to the appropriate outputs of the AURATON Floor Heating Controller, we can add the AURATON Heater Controller to the system, which can switch on the furnace and/or the pump.

• 

• 

• 

• 

• 

• 

For the system to operate correctly, select the "Heating" function, specify the furnace/pump channel in the AURATON Floor Heating Controller as the controller, and specify the AURATON Heater Controller as the actuator. From now on, whenever the AURATON Floor Heating Controller activates the furnace channel, the AURATON Heater Controller will also activate.

Additional notes

• The greater the distance of the tested regulator, the fewer indicator lights will light up.
• If only 1 or 2 LEDs are lit, consider changing the location of the controller/thermometer.

A maximum of 6 AURATON actuators can be connected to each zone.
