Introduction
UTN is an electronic thermostat for comfort heating. It 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. UTN thermostats have built-in GFCI (Ground Fault Circuit
Interrupter) 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

button on the top of the thermo-
stat. The test is successful if the red light in the
