Ground-Fault Protection - Pentair Raychem QuickStat-TC Manuel D'installation Et D'utilisation

Thermostat Controls and Display
The following figure shows the thermostat controls. The thermo-
stat has three temperature control modes:
• AF mode: (Default mode) Controls the system based on the
ambient air temperature and ensures that the floor tempera-
ture does not exceed the desired limits using an external floor
temperature sensor
• F mode: Controls the floor temperature using an external floor
sensor
• A mode: Controls the system based on the ambient air temper-
ature (does not use floor sensor)

1 Place the switch in Standby to cut power to the heater when
not in use (e.g., in the summer). This will not affect the time and
temperaturesettings.
2 To reset the ground-fault protection, switch the thermostat to
Standby and back to On.
3 The thermostat displays the percentage of heating time required
to maintain the desired temperature. For example,
when heating is activated 40 percent of the time.

seconds, then the actual measured temperature is displayed.
Date and Time Setting
The first time you power up the thermostat, the time and date will
flash and must be set.
1. Press the Hour button to set the hour.
2. Press the Min button to set the minutes.
3. Press the Day button to set the day.
4. Press Mode/Ret to exit.
Daylight Savings Time
The QuickStat-TC can automatically adjust for Daylight Savings
Time. When this function is enabled, the thermostat switches to
Daylight Savings Time on the second Sunday of March and to nor-
mal time on the first Sunday of November.

Ground-Fault Protection

he QuickStat-TC has a built-in GFCI (5 mA trip level). This
T
protects users against risks of electrocution by cutting off the
power to the floor heating system when the leakage current
exceeds 5 mA. If a ground-fault has occurred, the TEST light
on the top of the thermostat will illuminate red and GFI will
appear on the screen.
Testing the GFCI
Users should test the GFCI after the installation of the QuickNet
or CeraPro floor heating system is complete to ensure that the
ground-fault protection is in working order. Users should test the
GFCI on a monthly basis thereafter.
1. The GFCI can only be tested if the thermostat has a heating
demand. Increase the setpoint temperature above the current
measured temperature. Wait several seconds to allow the
100%
thermostat to adjust to the new set point and the heating
symbol appears.
2. Press the TEST button.
The test is successful if the TEST light on top of the thermostat
illuminates red and GFI appears on the screen.
The test has failed if the TEST light on top of the thermostat does
not illuminate red. In this case, turn the power off to the floor
heating system and check the installation of the thermostat.
Resetting the GFCI
If the GFCI has tripped, reset it by switching the thermostat to
Standby and back to On. The TEST light on top of the thermostat
will go off.
If the GFCI trips in normal operation without pressing the TEST
button, there could be a ground-fault. To check whether it is a
ground-fault or nuisance tripping, reset the GFCI. If the GFCI does
not trip after the reset, it was nuisance tripping and the system is
functioning properly. If the GFCI trips again after the reset, there
is a ground-fault. The user should contact a qualified electrician to
troubleshoot the issue.
