INSTALLATION

Before changing the thermostat, disconnect the heating system from the mains power in your home. This will prevent potential injury by electric current.

Installing the Thermostat

Place the thermostat in the stand included in the pack.
Connect the USB power supply (included) with the connected micro USB cable to 230 V mains.
Plug the micro USB cable into the bottom of the stand.

Placement of the Thermostat

The placement of the thermostat (transmitter unit) significantly affects its functioning.
Choose a location where members of the family spend most of their time, preferably near an inside wall where air circulates freely, with no direct sunlight.
Do not place the thermostat in the vicinity of heat sources (such as TV sets, radiators, fridges), or close to a door. Failure to comply with these recommendations will prevent proper control over room temperature.

PUTTING THE DEVICE INTO OPERATION

Pairing the Control Unit with the Switching Unit
Both thermostat units must be paired before first use. Pairing enables transmission of information between the control unit and the switching unit. Setting is done via automated pairing (self-learning).

Fit the thermostat gently onto the stand.
Connect the USB power supply with micro USB cable to 230 V mains and plug the cable into the stand.
Correctly connect the switching unit to voltage supply, turn the main switch to the position and long press (for at least 10 seconds) the M/A button; a green LED will begin flashing on the MANUAL button.
Long-press the and buttons on the thermostat (transmitter) for about 5 seconds the icon will start flashing.
Both units will be paired within 1 minute and the green diode on the switching unit will stop flashing.
If you want to change the pairing code of the two units or the thermostat does not function properly, repeat the entire pairing procedure from step 1 – the pairing code will be rewritten automatically.

Testing Wireless Communication between the Units

Use the button on the thermostat or use the app to set a temperature several degrees higher than the current room temperature.
The red LED on the switching unit will light up.
If the LED does not light up, move the control unit closer to the switching unit.
The maximum range between the control and switching unit is 100 m in an open space.
The range may decrease indoors as the signal has to pass through walls and other obstacles.

Main Switch

To turn on the switching unit, set the switch to the position. If the heating system is not used for an extended period of time, it is recommended to turn the switching unit off (switch the main switch to the position).

LED Indicators
