Long pressing +- will reset all values to their default

Displaying the current temperature:

The thermostat will display the current temperature in oC by default. When in any other mode making no input for approximately 5 seconds will cause the thermostat to return to this default display.

Setting the trigger temperature W1209 Temperature controller LED:

To set the trigger temperature press the button marked ‘SET’. The seven segment display will flash. You can now set a trigger temperature (in oC) using the ‘+’ and ‘-‘ buttons in 0.1 degree increments. If no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the display will return back to the current temperature. e578443#

Setting the parameters:

To set any parameter first long press the ‘SET’ button for at least 5 seconds. The seven segment display should now display ‘P0’. This represents parameter P0. Pressing the ‘+’ or ‘-‘ buttons will cycle though the various parameters (P0 to P6). Pressing the ‘SET’ button whilst any of there parameters are displayed will allow you to change the value for that parameter using the ‘+’ and ‘-‘ buttons (see below). When finished setting a parameter press the set button to exit that option. If no buttons are pressed for approximately 5 seconds the thermostat will exit the parameter options and will return back to the default temperature display.

Setting the cooling or heating parameter P0:

The parameter P0 has two settings, C and H. When set to C (cooling) the controller will turn on the cooling system to drive the temperature down to the trigger temperature. Once at this temperature the controller will turn off the cooling. When the temperature drifts back to the set point + hysteresis (see parameter P2) the controller will turn the cooling system back on.
When set to H (heating) the controller will turn on a heater to drive the temperature up to the trigger temperature. Once at this temperature the controller will turn the heating off. When the temperature drops back down to the setpoint – hysteresis (see parameter P2) the controller will turn the heating system back on.
