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.

You can choose one preset configuration:

Preset	Configuration	Control type / Set point range	*Cycle time (min)**
P1	Heat Pump/Oil Boiler (Room sensor)	Room Control 4°C ~ 30°C	20
P2	Hydronic Radiator/Gas Boiler (Room sensor)		10
P3	Hydronic Underfloor (Room sensor)		10
P4	Electrical Radiator (Room sensor)		10
P5	Electrical Underfloor (Room sensor - without floor limit sensor)		10
P6	Electrical Underfloor (Room sensor - with floor limit sensor)		10

*Cycle time: This setting determines the length of each on/off cycle of the output relay. The percentage of time within that cycle time that the relay is on is varied based on demand. 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 indicate Preset 5 is selected.

Modifying the preset value

When the rotary push-button is turned clockwise, it increases the preset value by 1 and rotating rotary push-button anti-clockwise, it decreases the preset value by 1.

For example, when the rotary push-button is turned clockwise, preset P1 becomes P2, continue rotating the rotary push-button clockwise, and the preset changes to P3, P4...P6.

Similarly, when the rotary push-button is turned anti-clockwise, preset P6 changes to P5; if the rotary push-button is continue rotating anti-clockwise, preset P4, P3...P1.

Confirming the preset
Select the preset that meets your needs by turning the rotary push-button, and then hold the rotary push-button for > 1 s to confirm the selection.

For example, P1 is confirmed.

Cycle Time : 20 mins
Valve Protection : Off

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