Choosing the right location for AURATON Pavo R

The correct operation of AURATON Pavo R is largely influenced by its location. Using the device in a place with no air circulation or a place with direct sunlight may result in incorrect temperature control. AURATON Pavo R should be installed on the internal wall of a building (a partition wall), in an environment with free air circulation. You should avoid proximity to heat-emitting devices (TV, heaters, refrigerators) or locations exposed to direct sunlight. The vicinity of doors and exposing AURATON Pavo R to possible vibrations may also cause problems with proper operation of the device.

Battery replacement

X

If the low battery symbol (X) appears on the display, it means that the battery level has fallen to the minimum allowable level. Replace the batteries as soon as possible.

Mounting AURATON Pavo R – the weekly, wired thermostat

In order to mount AURATON Pavo R on the wall:

1. Drill two holes 6 mm in diameter in the wall (mark the hole spacing using the template attached to the manual).
2. Insert the wall plugs (included).
3. Tighten the left screw with a 3 mm clearance.
4. Place AURATON Pavo R through the screw head and slide to the right (note the keyhole-like opening on the rear cover of AURATON Pavo R).

5. Tighten up the right screw so that it holds AURATON Pavo R mounted securely.

Programming

The AURATON Pavo R memory stores up to eight weekday programs, eight Saturday programs and the same number of Sunday programs. This allows exceptionally precise planning of the temperature in the building depending on the time of day.

Factory programs (to be modified)

To start programming:

1. Program selection

Use the bc buttons to select the desired program number 9, to be assigned the following parameters:
– the temperature to be controlled,
– the day of the week on which it is to operate,
– the start time.

2. Assigning a day to the program

Confirm the selection with the j button. The z segment and the program number being edited will start flashing again on the display.

3. Assigning temperature to the program

4. Assigning the start time to the program

Repeat the procedure for consecutive programs. Confirm the above settings with the j button.

Deleting a program

Notes:

1. Programs with the same numbers but assigned to different days may have completely different settings. For example, program 1 on Saturday can start at 8:00 and program 1 on Sunday can start at 10:00.
2. Days from 1 to 5 (Monday to Friday) have the same programs.
3. For the same day of the week, the next edited program should start at least a minute later than the previous one. Otherwise, AURATON Pavo R will renumber the programs to preserve the chronology of the temperature settings.
4. For the selected day of the week, the temperature programming period must not exceed 24 hours – the last program can start no later than a minute before the first one.
5. If all programs are inactive, AURATON Pavo R remains turned off.

Programming the manual, holiday and anti-freeze temperatures

AURATON Pavo R allows you to programme 3 types of temperature:

• Manual temperature (V) – in the range of 5 to 30°C
• Holiday temperature (Z) – in the range of 5 to 30°C
• Anti-freeze temperature (U) – in the range of 4 to 10°C

To set one of the above temperatures:

Manual control

V

If you want to discontinue the current program operation and extend maintaining the day temperature for any reason, you can do it manually.

1. Press the p button, the w and V segments will start flashing. The temperature field will enter the setting mode, with the previously programmed temperature value set as default. Use the bc buttons to set the desired value and confirm the selection with the j button.
2. To disable the manual control mode, press the p button.

Holiday mode

Z

To suspend the operation of programs for a longer period, use the holiday mode. When this option is active AURATON Pavo R only maintains the ‘holiday temperature’ (see chapter: ‘Temperature programming’).
The maximum duration of the holiday mode is 6 days, 23 hours and 59 minutes.

To enable the holiday mode:

During the holiday mode, the Z symbol will be displayed on the screen. You can always deactivate the holiday mode sooner by pressing the p button.

Anti-freeze mode

U

AURATON Pavo R is equipped with an anti-freeze temperature setting. It can be set in the range of 4 to 10°C (the factory setting is 7°C).
We use the anti-freeze mode during a prolonged period of absence, to prevent the freezing of water in the heating system.

1. To activate the anti-freeze mode, simply press the q, button and the display will show the symbol U button.
2. To deactivate the anti-freeze mode, press the q or p button.

Turning off the receiver temporarily

0
Pressing and holding q for 5 seconds turns off the relay in the AURATON Fornax receiver and for 10 seconds the display flashes the s segment and all the set parameters of the current program: the day of week, the temperature and the end time of the program operation.
Pressing the j key again returns AURATON Pavo R to its normal operating mode.

Heating device operating time meter

Pressing and holding the j button for 3 seconds activates the t function that counts the operating time of the heating device during the last 24 hours. Pressing the j button again will bring up the segment representing the u function, counting the total number of the heating device operating days.

Pressing the j button returns AURATON Pavo R to its normal operating mode.

Description of the AURATON Fornax

weekly, wired thermostat (transmitter)

AURATON Fornax (receiver) cooperates with the wireless AURATON Pavo R regulator (transmitter). The receiver is mounted next to the heating device and can work under a load up to 16 A/10 A .

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 Fornax receiver to the wall with the screws, so that the device is fixed securely.

Pairing

the weekly, wireless thermostat (transmitter) AURATON Pavo R with the wireless heating device controller (receiver) AURATON Fornax

After connecting to the mains, switch the receiver on by briefly pressing the power button (F). When the device is switched on, the green power diode lights up and there is an audible single sound signal. To switch off the AURATON Fornax e.g. outside the heating season, hold down the power button for 3 seconds until there is an audible double sound signal, and the green power diode switches off, which means that the heating device has also been switched off.

1. Pairing AURATON Pavo R (transmitter) with AURATON Fornax is initiated by pressing the right pairing button (D) – a single sound signal on the AURATON Fornax receiver and holding it for at least 3 seconds until the LED starts blinking green (a double sound signal), then release the button.
   The AURATON Fornax receiver will wait for pairing for 120 seconds. After this period, it will automatically return to its normal operation.
2. Press the h button on AURATON Pavo R (transmitter) for 5 seconds until the broadcast symbol (=) lights up on the display. Release the button – AURATON Pavo R transmits the pairing signal for 5 seconds.
3. Successful completion of pairing is signalled when the green LED diode on the AURATON Fornax receiver is no longer blinking, a single sound signal is heard, and the receiver returns to normal operation.

If there is a pairing error, please repeat steps 1 and 2. In case of further errors, unpair the device by RESETTING the AURATON Fornax receiver, see “RESET – Unpairing a device paired with AURATON Fornax – wireless heating or air-conditioning device controller (receiver)” and trying to pair the devices again.

Signalling the working status and data package reception

Each reception of radio transmission from a paired device is signalled by the AURATON Fornax receiver by a temporary alternating colour change of the LED diodes. When the relay is turned on, the LED diode is red and when the relay is turned off, the LED diode is green.

Unpairing AURATON Pavo R – weekly, wireless thermostat paired with AURATON Fornax

1. To initiate the unpairing of AURATON Pavo R (transmitter) paired with the AURATON Fornax receiver, press the left unpairing button (E) on the receiver and hold it for at least 3 seconds, until the LED diode starts blinking red, then release the button. The sound signals work in the same way as in the case of pairing, i.e. pressing a button is signalled by a short sound signal and after 3 seconds a double short sound signal is heard.
   The AURATON Fornax receiver waits for the device to be unpaired for 120 seconds. After this time elapses, it will automatically return to normal operation.
2. Press the h button on AURATON Pavo R (transmitter) for 5 seconds until the broadcast symbol (=) lights up on the display. Release the button.
3. Successful completion of unpairing is signalled when the red LED diode on the AURATON Fornax receiver is no longer blinking, a single sound signal is heard, and the receiver returns to normal operation.

If there is an unpairing error, please repeat steps 1 and 2. In case of further errors, unpair the paired device, see “RESET – Unpairing a device paired with AURATON Fornax – wireless heating or air-conditioning device controller (receiver)”..

RESET – Unpairing a device paired with AURATON Fornax – wireless heating device (receiver)

To unpair a paired device (e.g. AURATON Pavo R) from AURATON Fornax, simultaneously press and hold the two pairing and unpairing buttons (D and E) pfor at least 5 seconds until the LED diode signalling changes to alternately blinking green and red. Then release both buttons. Sound signalling: pressing the button a short signal – after 5 seconds, a double short signal.
Successful completion of unpairing is signalled after about 2 seconds with the signalling changed to green and then its short fading out.

RESET AURATON Pavo R

Pressing the RESET button (.) clears the time and day and restarts AURATON Pavo R.

The RESET function of AURATON Pavo R

The MASTER RESET function restores factory settings. It is activated by pressing the j and RESET (.) buttons simultaneously.

Configuration settings

Configuration settings are set one after another:

To enter the edit mode of the configuration settings, hold the b and c buttons simultaneously for 5 seconds until the display backlight starts flashing.

Changing the backlight colour

Changes in hysteresis

The hysteresis change mode is signaled by a flashing HI. Turn the knob to the left or right to set the desired hysteresis.
HI 2 – ±0,2 °C (preset),
HI 4 – ±0,4 °C,
HI P – PWM operating mode (see chapter “PWM operating mode”).

Confirm your choice by pressing the j button. AURATON Pavo R will proceed to change the next parameter.

Offset change

Offset allows you to calibrate temperature indications with a tolerance of ± 3°C. AURATON Pavo R may for example show that the temperature in the room is 23°C, while a regular room thermometer next to it may show 24°C. Changing the offset by +1 degree, will make AURATON Pavo R show the same temperature as the room thermometer.

Clock calibration

This function is used to correct the clock indications in case of any deviations. If the clock is working incorrectly within a week, the extent of incorrect clock indications should be determined. This value should be entered in AURATON Pavo R in the form of seconds.

Example 1:
After a week of operation, AURATON Pavo R shows time accelerated by 1 minute and 20 seconds (60 + 20 = 80). In this case you should slow down the clock by setting C -80.

Example 2:
After a week of operation, the clock in AURATON Pavo R is 2 minutes slow (2 x 60 = 120). In this case you should speed up the clock by setting C 120.

PWM operating mode

 (Pulse-Width Modulation)

By changing the hysteresis settings (chapter “Configuration settings”), you can turn on the PWM operating mode. In this mode, AURATON Pavo R cyclically turns on the heating device in order to minimize temperature fluctuations. AURATON Pavo R checks temperature rise times and temperature drop times.

Knowing these values makes AURATON Pavo R turn on and off the heating device in appropriate cycles to maintain the temperature to the set value as close as possible.

Special cases

• When 3 consecutive transmissions are lost (after 15 minutes), the AURATON thermostat (transmitter) will signal a failure on the AURATON Fornax receiver (the LED diode will alternate blinking red and green). Until the problem is resolved, the receiver will enter the stored on/off cycle from the last 24 hours.
• When the signal from the AURATON thermostat returns, the error is cleared and the AURATON Fornax receiver returns to normal operation.

Unique features of AURATON Fornax

• 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.
• The AURATON Fornax receiver is equipped with a unique algorithm for analysing the on/off cycles. The entire heating cycle from the last 24 hours is stored in AURATON Fornax memory. In the event of loss of communication with the AURATON wireless thermostat (transmitter), AURATON Fornax will automatically execute the stored on/off cycle from the last 24 hours. This gives you time to restore the transmission (solve issues with interference) or repair the thermostat without a significant deterioration of the thermal comfort in the controlled facility.

Additional remarks

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