Choosing the right location for AURATON Pavo

The correct operation of AURATON Pavo 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 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 to possible vibrations may also cause problems with proper operation of the device.

Connecting cables to AURATON Pavo

The terminals are located on the back of AURATON Pavo. It is a typical single-pole double-throw relay. In most cases, the NC terminal is not used.

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.

IMPORTANT:
In order to maintain any programmed parameters, the battery replacement operation should not exceed 30 seconds.
NOTE:
We recommend using alkaline batteries to power AURATON thermostats. Do not use “rechargeable batteries” because their rated voltage is too low.

Mounting AURATON Pavo – the weekly, wired thermostat

In order to mount AURATON Pavo 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 through the screw head and slide to the right (note the keyhole-like opening on the rear cover of AURATON Pavo).
  1. Tighten up the right screw so that it holds AURATON Pavo mounted securely.
NOTE:
In the case of a wooden wall, there is no need to use wall plugs. It is enough to drill holes with a diameter of 2.7 mm (instead of 6 mm) and screw the screws directly into the wood.

Turning AURATON Pavo on for the first time

After inserting the batteries correctly into the battery compartment, the LCD screen will display all the segments for a second (display test) and then the software version number.

After a while, AURATON Pavo will automatically go to the hour setting. An item flashing on the screen indicates that it is currently in editing mode. Use the bc buttons to set the desired hour and confirm the setting with the j button.

AURATON Pavo will go to the minute setting. Use the bc buttons again to set the desired minute value and confirm the setting by pressing the j button.

A flashing day of the week symbol appears in the upper left corner. Use the bc buttons to set the desired day and confirm the selection with the j. button. AURATON Pavo will enter its normal operating mode.

    button, set the end day of the holiday mode. The x segment will start flashing on the screen. Use the bc buttons to set the end day of the holiday mode.
  2. Confirm the above settings with the j button.
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 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

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 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.

NOTE:
The time may be different from the actual operating time of the heating device, e.g. due to the existence of internal thermostats installed in heating devices.
Pressing the j button returns AURATON Pavo to its normal operating mode.
NOTE:
The total number of operating days of the heating device can be reset to zero in the u mode after pressing and holding j for 5 seconds.
NOTE:
The ‘RESET’ function of AURATON Pavo resets both operating time meters to zero.

The RESET function of AURATON Pavo

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

The MASTER RESET function of AURATON Pavo

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

NOTE:
All user programs will be deleted!

Clock
calibration

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

A flashing backlight means that the bc buttons can be used to change the backlight colour. Confirm the selection with the j button. AURATON Pavo will go to the next parameter changing mode.

Changes in hysteresis

Hysteresis is supposed to prevent too frequent activation of the actuator due to small temperature fluctuations.
For example, in the case of HI 2 hysteresis, when the temperature is set to 20 °C, the boiler will be switched on at 19.8 °C, and switched off at 20.2 °C. In the case of HI 4 hysteresis, when the temperature is set to 20 °C, the boiler will be switched on at 19.6 °C, and switched off at 20.4 °C.

The hysteresis change mode is signaled by a flashing HI. Use the bc buttons 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 AURATON Pavo will proceed to change the next parameter.

Changes in the delay

The delay prevents too frequent activation of the actuator, e.g. due to temporary drafts (caused by opening the window, etc.).

The delay change mode is signaled by a flashing 90:SE
Use the bc buttons to activate or deactivate the delay.

90:SE – a delay of 90 seconds (factory setting)
0:SE – no delay
Confirm the selection with the j button. AURATON Pavo returns to its normal operating mode.

Offset change

Offset allows you to calibrate temperature indications with a tolerance of ± 3°C. AURATON Pavo 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 show the same temperature as the room thermometer.

The offset changing mode is signalled by the flashing text OFFS. Use the bc buttons to set the desired value between -3.0 and 3.0 (the factory setting is 0.0). Confirm the selection with the j button. AURATON Pavo will return to its normal operating mode.

IMPORTANT:
If no button is pressed for 10 seconds while changing the configuration settings, AURATON Pavo will return to the normal operating mode.
IMPORTANT:
Pressing any function button for the first time always turns on the backlight, and then the function of a specific button.

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 in the form of seconds.

Example 1:
After a week of operation, AURATON Pavo 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 is 2 minutes slow (2 x 60 = 120). In this case you should speed up the clock by setting C 120.

IMPORTANT:
The number of seconds should be determined after one week of operation of AURATON Pavo for the clock calibration function to work correctly (7 days = the number of seconds to be added or subtracted, maximum 294 seconds).
IMPORTANT:
If no button is pressed for 10 seconds while changing the configuration settings, AURATON Pavo will return to the normal operating mode.

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 cyclically turns on the heating device in order to minimize temperature fluctuations. AURATON Pavo checks temperature rise times and temperature drop times.

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

  1. Temperature
  2. Time
  3. Set temperature
  4. Room temperature
IMPORTANT:
AURATON Pavo can turn on the heating device despite the fact that the temperature in the room is higher than the set temperature in the PWM mode. This is caused by the PWM algorithm aiming at maintaining the set temperature and anticipating the behavior of the thermal system.
