Introduction
The Danfoss LX thermostat combines elegant simplicity with
advanced technology and features a large, easily read temperature
display and Easy2Use buttons for simple operation. The backlit
display is activated by the first press of a button. All Danfoss LX
thermostats have GFCI (Ground Fault Circuit Interrupter) protec-
tion to ensure maximum safety.
Setting the temperature
To set the temperature, press the UP or DOWN button until the
required temperature is shown on the display.
The thermostat will calculate the best way to control the heating
in order to obtain the required temperature. Minor adjustments
should first be made after a few hours, depending on floor heating
design.
Ground Fault Circuit Interrupter (GFCI)
The thermostat has a built-in GFCI that ensures personal safety in
case of ground faults.
It is important that the GFCI is checked monthly.
Checking the GFCI
Testing can only be performed while the thermostat is calling for
heat. Adjust the setpoint until the heating symbol ( ) appears.
Use the Up button to increase the heating demand and then press
the OK button. Wait 10 seconds to allow the thermostat to adjust
to the new setpoint. Then press the TEST button on the top of
the thermostat. The test is successful if the red light in the TEST
button lights up and GROUND FAULT is shown on the display. If
this does not occur, check the installation/contact your electrical
installer. Press the Standby/Reset button to reset the GFCI.
The red light should go out and the display returns to normal ap-
pearance.
