Wireless controller of a circulation pump in the DHW system activated by a motion sensor

(set)

Congratulations on your purchase of a modern set – a wireless DHW circulation pump controller. activated by a motion sensor AURATON Aquarius SET.

Wireless controller of a circulation pump in the DHW system activated by the AURATON Aquarius SET motion sensor is designed to support the “intelligent circulation” of the DHW circuit. The circulation pump connected to the AURATON Aquarius CR output is activated only when the AURATON Aquarius PIR motion sensor detects the activity of the domestic hot water users in the room (e.g. in the bathroom). Additionally, AURATON Aquarius CR activates the circulating pump only for a pre-set time (factory set to 2 minutes).

	The lithium battery (CR 123A 3V) used allows for many years of uninterrupted operation of the motion sensor.
16A	Work under load up to 16 A/10 A The AURATON Aquarius CR receiver is equipped with a relay that can operate under a load of up to 16 A/10 A. The low-spark technology of switching the mains voltage causes minimal wear of the relay contacts.
	Interference-free communication between devices. The AURATON Aquarius PIR and AURATON Aquarius CR communicate at 868 MHz. Very short, encrypted data transmission packets (approx. 0.004 sec.) ensure efficient and interference-free operation of the device.

Mounting AURATON Aquarius CR

(receiver)

1. mounting plug

Remove the cover of the front part of AURATON Aquarius CR by unscrewing the screws halfway.

Connect the heating or air-conditioning device to the clips of the AURATON Aquarius CR control connector. Follow the service manual of the heating or air-conditioning device. COM (common) and NO (normally open circuit) clips are most commonly used.

Connect the power supply wires to the clips of the power supply connector of the AURATON Aquarius CR receiver, observing safety rules.

1. Wire mounting bracket.

Once the wires are connected, secure them with the “wire mounting bracket” and screw the cover back onto the AURATON Aquarius CR receiver.

Mounting AURATON Aquarius CR onto a wall

To fix AURATON Aquarius CR to a wall:

1. Remove the cover from the front part of the receiver see chapter “Mounting the AURATON Aquarius CR receiver heating or air-conditioning device controller (receiver)”.
2. Mark the location of the holes for the mounting screws on the wall.
3. Drill holes with diameters of the attached plugs (5 mm) where marked.
4. Insert wall plugs into the drilled holes.
5. Screw the AURATON Aquarius CR receiver to the wall with the screws, so that the device is fixed securely.

Choosing the right location for the wireless motion sensor controlling the circulation pump in the domestic hot water system AURATON Aquarius PIR

The motion sensor should be installed in such a place that it can easily detect the user’s movement. It should not be installed behind obstacles or ensclosed. Avoid installing at too low a height (minimum 0.5 m above the ground). These types of sensors are usually ceiling-mounted at a height of about 2.5 m.

Pairing the AURATON Aquarius PIR with the AURATON Aquarius CR

1. Pairing the Aquarius PIR with the Aquarius CR is initiated by pressing the pairing button – single beep (D) on the Aquarius CR pump controller and holding for at least 3s, until the LED flashes green (double beep), then releasing the button.
   The AURATON Aquarius CR waits 120 seconds for pairing. After this time elapses, it will automatically return to normal operation.
2. On the Aquarius PIR press the pairing button (.) located on the back of the housing and hold for at least 2 seconds until the LED on the front of the motion sensor lights up red. Release the button.
3. Successful completion of pairing is signalled by the LED on the Aquarius CR no longer flashing green. The green LED will go out for 1 second and then signal the currently set pump operating time (factory set 2 minutes – 2x green LED flash every 0.5 seconds), and then the Aquarius CR will return to normal operation.

If there is a pairing error, please repeat steps 1 and 2. In the event of further errors, unpair all devices via a RESET of the Aquarius CR (see “RESET – return to factory settings”) and try pairing the devices again.

Unpairing the AURATON Aquarius PIR from the AURATON Aquarius CR

1. Unpairing the AURATON Aquarius PIR from the AURATON Aquarius CR is initiated by pressing the unpairing button (E) on the pump controller and holding it for at least 2 seconds, until the LED starts flashing red, then releasing the button.
   The AURATON Aquarius CR waits 120 seconds for unpairing. After this time elapses, it will automatically return to normal operation.
2. On the Aquarius PIR press the pairing button (.) located on the back of the housing and hold for at least 2 seconds until the LED on the front of the motion sensor lights up red. Release the button.
3. Successful completion of unpairing is signalled when the red LED on the AURATON Aquarius CR pump controller receiver is no longer blinking and it returns to normal operation.

If there is a pairing error, please repeat steps 1 and 2. In the event of further errors, unpair all devices via a RESET of the AURATON Aquarius CR (see “RESET – return to factory settings”) and try pairing the devices again.

RESET – return to factory settings

In order to unpair all the paired devices in the AURATON Aquarius CR, press and hold both the unpairing and pairing buttons (D and E) simultaneously for at least 5 s until the LED signalling changes to alternately blinking green and red. Then release both buttons.

Successful completion of unpairing is signalled after about 2 seconds with the signalling changing to green and then shortly fading out.

Signalling the working status and data package reception

Each reception of a radio transmission by the AURATON Aquarius CR from a paired AURATON Aquarius PIR is signalled by a temporary alternating colour change of the LEDs.
When the relay is turned on, the LED is red and when the relay is turned off, the LED is green.

Change of operating time/interval and operating algorithm

Changing the interval of the domestic hot water pump:
Briefly pressing the unpairing button (E) sets the pump interval time in a sequence of 1, 5, 10, 15 minutes, depending on how many times the button is pressed (from 1 to 4 and then looping around).

Changing the domestic hot water pump operating time:
riefly pressing the pairing button (D) sets the pump operating time for as many minutes as pressed. From 1 to 5 minutes. Pressing a sixth time goes back to 1 minute again.

At the end the AURATON Aquarius CR will show the domestic hot water pump operating time with the appropriate number of green flashes and the interval time of the domestic hot water pump with the appropriate number of red flashes.

After switching the circulation pump off (after the set time) the AURATON Aquarius CR will not switch the pump on for 15 minutes despite receiving signals from the AURATON Aquarius PIR concerning detecting movement. This is to prevent the domestic hot water pump from switching on too frequently. It will only be switched on again after receiving another movement signal from the AURATON Aquarius PIR.

Unique features of the set – wireless circulation pump controller in the DHW system activated by the AURATON Aquarius SET motion sensor

• The lithium battery (CR 123A 3V) used allows for many years of uninterrupted operation.
• Relay switching is synchronised with the 230 V AC power supply line so that the closing and opening of the relay armature contacts always occurs in the area of the voltage waveform reaching zero. This prevents the formation of an electric arc and significantly extends the life of the relay.
• Activation of the pump after detection of movement brings considerable savings in energy consumption by the domestic hot water pump and in the cooling down of the domestic hot water in comparison to other systems.

Additional information

• The AURATON thermostat (transmitter) must be installed at least 1 metre away from AURATON Aquarius CR (too strong a signal from the transmitter may cause interference).
• At least 30 seconds must elapse between turning the relay off and on.
• TData from the AURATON thermostat (transmitter) is transmitted to the AURATON Aquarius CR receiver every time the ambient temperature changes by 0.2°C. If the temperature does not change, the thermostat transmits control data every 5 minutes (this is signalled by a temporary alteration in the colour of the LED diodes).
• In the event of a power failure, AURATON Aquarius CR will switch off. After power is restored, the heating device will automatically switch on, and AURATON Aquarius CR will wait for a signal from the paired AURATON thermostat (transmitter) no longer than 5 minutes after power is restored. After receiving the signal, AURATON Aquarius CR will return to normal operation.
• Placing AURATON Aquarius CR in a metal housing (e.g. mounting box, metal housing of a furnace) will interfere with the operation of the thermostat.
