7.3 Testing the Ground Fault Protection
To ensure the ground fault protection is always in working order, test
it once the thermostat is installed and test it every month thereafter.
n
Increase the temperature sufficiently to start heating.
o Wait for about 5 seconds until the heat intensity indicator ( )
appears on the screen.
p Press the TEST button-light.
• If the TEST button-light does NOT illuminate, the test has
failed. Cut power to the heating system at the main electrical
panel, have an electrician verify the installation and, if neces-
sary, replace the thermostat.
• If the TEST button-light illuminates, continue to step 4.
q
Switch the thermostat to Off then back to On.
• If the TEST button-light goes off, the test has passed. Set
the thermostat back to the desired temperature and ignore the
remaining steps. The test is now completed.
• If the TEST button-light remains on, the test has failed. Con-
tinue to step 5.
r
Switch the circuit breaker (at the service panel) of the heating
system to off then back to on.
s
Repeat the test. If the test fails again, cut power to the heating
system at the main electrical panel, have an electrician verify the
installation and, if necessary, replace the thermostat.
The thermostat normally displays the actual temperature. To view the
setpoint temperature, press one of the
buttons once. The set-
point will be displayed for 5 seconds. To change the setpoint, press
and release one of the
buttons until the desired temperature is
displayed. To scroll the setpoint faster, press and hold the button.
Backlight
When you press on either of the
buttons, the display is lit for 10
seconds. The setpoint appears for 5 seconds, then the actual tem-
perature is displayed.
NOTE: The floor temperature limits are used only if your thermostat
is configured in AF mode.
The thermostat normally turns the floor heating system On or Off to
control the ambient temperature. However, if the floor temperature
drops below the minimum limit or rises above the maximum limit, the
thermostat will turn heating On or Off respectively to maintain the
floor temperature within the set limits, regardless of the ambient tem-
perature.
The minimum and maximum floor temperature limits are factory-set
at 10 °C (50 °F) and 28 °C (82 °F) respectively. To modify the limits,
proceed as follows:
n
Press the Floor Limit button for 3 seconds. The ther-
mostat will display the minimum limit.
o Press the buttons to set the minimum limit.
p
Press the Floor Temperature Limit button briefly. The
thermostat will display the maximum limit.
q
Press the buttons to set the maximum limit.
r
Press the Floor Limit button for 3 seconds to exit the
menu and save your modifications.
NOTE: The thermostat will also exit the menu and save your modifi-
cations if you do not press any button for 60 seconds.
