Device presetting

You can configure a preset during the initial power-on or immediately after performing a factory reset. The thermostat requires a preset selection to apply predefined settings based on the application it controls. This ensures proper functionality for the intended use case. Preset selection is a manual process. All presets use a PI control algorithm, which delivers highly stable performance.

PI (Proportional and Integral) controller: It is a widely used control method. It minimizes the error between the desired setpoint and the actual value by applying feedback-based corrections.

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
P8	Electrical Underfloor	Floor Control	10
P9	Regulator Mode (output displayed is based on percentage)	Floor Control 0 ~ 10 (0% ~ 100%)	30

Cycle time: The Cycle Time setting defines the duration of each on/off cycle for the output relay. Within a cycle time, the relay cycle (On/Off switching action) operates based on the demand setpoint.
A longer cycle time may be more appropriate for slow heating surfaces, such as concrete floors. A short cycle time is more appropriate for faster heating surfaces, such as electric panel heaters.

Initial preset configuration (by default):

When the thermostat is powered on for the first time or immediately after a factory reset, the Dot-matrix LED displays following default presets.

P5 flashes if there is no external sensor connected.
P8 flashes if there is any external sensor connected.

To modify the default preset value:

Press O and + buttons simultaneously for 10 seconds to enter the preset changing mode
Press + button to increase the preset value from P1 to P2.
Press – button to decrease the preset value from P2 to P1.

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.

To confirm the preset selection:

Select the preset that meets your needs using the +/- buttons.
Press and hold O button for more than 1 second 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 selected and the thermostat is connected to an external floor sensor, you must 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.
