Device presetting

You can preset the thermostat on the first power-on or immediately after a factory reset. The thermostat will require the selection of a preset to pre-configure settings depending on what the thermostat is directly controlling, which allows the thermostat to function correctly for the intended use case. Preset selection is a manual process and all preset uses a PI* control algorithm which provides highly stable results.

*PI (Proportional and Integral) controller is a commonly used method in control systems to correct for error between the commanded setpoint and the actual value based on some type of feedback

You can choose one preset configuration:

Preset	Configuration	Control type / Set point range	*Cycle time (min)**
P1	Heat Pump/Oil Boiler	Room Control 4°C ~ 30°C	20
P2	Hydronic Radiator/Gas Boiler		10
P3	Hydronic Underfloor		10
P4	Electrical Radiator		10
P5	Electrical Underfloor (Without floor limits)		10
P6	Electrical Underfloor (With floor limits)		10
P7	Hydronic Underfloor	Floor Control 10°C ~ 40°C	10
P8	Electrical Underfloor	Floor Control 10°C ~ 40°C	10
P9	Regulator Mode (output displayed is based on percentage)	Floor Control 0 ~ 10 (0% ~ 100%)	30

**Cycle time: This setting determines the length of each on/off cycle of the output relay. In a cycle time, the time interval between relay cycle is based on the demand setpoint. A longer cycle time may be more appropriate for slow heating surfaces, such as a concrete floor. A short cycle time is more appropriate for faster heating surfaces, such as an electric panel heater.

Initial preset configuration (by default)

When the thermostat is first powered on or immediately after a factory reset, by default “P5” flashes on the matrix LED’s if there is no external sensor connected, or “P8” if there is any external sensor connected.

Modifying the preset value

To modify the preset from default value, simultaneously press "O" and "+" for 10 s to enter advanced settings menu. Then press + button on the thermostat, it increases the preset value by 1 and when – button is pressed, it decreases the preset value by 1.

For example, when + button is pressed, preset P1 becomes P2, continue to press the + button, and the preset changes to P3, P4...P9.

Similarly, when – button is pressed, preset P9 changes to P8, continue to press the – button, preset changes to P7, P6...P1.

Confirming the preset
Select the preset that meets your needs using the +/- buttons, and then hold the O for > 1 s to confirm the selection.

For example, P1 is confirmed.

Cycle Time : 20 mins
Valve Protection : Off

If the preset value of P6, P7 or P8 is set and the thermostat is connected with an external floor sensor then you need to set the sensor type. Refer manual sensor settings.

NOTE: After configuring the thermostat, if you want to change or modify the preset or sensor setting, press O and + button simultaneously to enter preset selection and continue the process.
