T105RF Wireless Communication

Changing the Communication Code

It is recommended to change the communication code to one other than the factory default to prevent interference from other wireless devices.

Method:

Use DIP switches numbered 1-5 located inside the thermostat.

Procedure:

Set DIP switches randomly, ensuring they are in the same position on both the receiver and the transmitter.

After changing communication codes, reset the regulator by pressing the [RESET button].

Operating Modes and Programming

Auto-adapt Function

The auto-adapt function adjusts the operation of the heating device to ensure the comfort temperature is reached at the specified time. This feature activates when the room temperature is lower than the comfort temperature in the upcoming program. The pre-heating duration depends on the current temperature difference; a larger difference means earlier activation. The minimum auto-adapt time is 10 minutes before the programmed program, and the maximum is 50 minutes.

Setting Time

1. Press the [Time set button], then use the [Decrease button] or [Increase button] to set the day of the week.
2. Press the [Time set button] again, then use the [Decrease button] or [Increase button] to set the hour.
3. Press the [Time set button] again, then use the [Decrease button] or [Increase button] to set the minutes.
4. Press the [Time set button] or wait 10 seconds to confirm the time setting.

Setting Economic/Comfort Temperature

1. Press the [Comfort/Economic temperature button]. Use the [Decrease button] or [Increase button] to select the desired temperature.
2. The display will show the currently set comfortable or economic temperature. To change this value, press the [Decrease button] or [Increase button].
3. Press the [Comfort/Economic temperature button] or wait 10 seconds to confirm the temperature setting.

Programs

There are 9 programs available. Programs 1-6 are factory-set programs. Programs 7-9 can be defined by the user.

Selecting Factory Programs (1-6)

1. Press the [Weekly programming button], then use the [Decrease button] or [Increase button] to choose the programming method for days of the week:
   • Each day separately (1, 2, 3, 4, 5, 6 or 7)
   • Business days and weekend (5+2)
   • Whole week (7)
2. Press the [Weekly programming button] again, then use the [Decrease button] or [Increase button] to select program 1-6 for the chosen days.
3. Press the [Weekly programming button] to confirm the selection.

Choosing and Programming User Programs (7-9)

1. Press the [Weekly programming button], then use the [Decrease button] or [Increase button] to choose the programming method for days of the week (same options as above).
2. Press the [Weekly programming button] again, then use the [Decrease button] or [Increase button] to select program 7-9 for the chosen days.
3. Press the [Weekly programming button]. Use the [Decrease button] or [Increase button] to adjust the hour, and the [Comfort/Economic temperature button] to assign the comfortable or economic temperature for the specified hour. Repeat for all desired hours.
4. Press the [Weekly programming button] to finish defining the program.

Antifrost Mode

Activate Antifrost Mode by simultaneously holding down the [Decrease button] and [Increase button] keys. This mode sets the temperature to 7°C (for heating mode only) and remains active until the next program change. To exit Antifrost Mode, press any key on the thermostat.

Service Parameters

Service parameters can be changed using DIP switches numbered 1-3 located inside the thermostat.

Selecting Heating/Cooling Mode

This is changed by DIP switch #3. When the switch is in the upper position (ON), the thermostat operates in heating mode. When the switch is in the down position (OFF), it operates in cooling mode.

Setting Hysteresis (Span)

Hysteresis (Span) is set using DIP switches #1 and #2. The selectable hysteresis values are presented in the table below:
