GENERAL INFORMATION

Use of this Manual

This manual covers the installation and operation of the Raychem
QuickStat-TC thermostat and must be used with the following
document:

• QuickNet System Installation Manual (H57704)
Important: For the Pentair Thermal Management warranty and

agency approvals to apply, the instructions included in this manual
and product packages must be followed.

Features

The QuickStat-TC is an electronic thermostat that must be used
with the Raychem QuickNet floor heating mats.

QuickStat-TC provides the following features:

• Integrated Class A, Ground-Fault Circuit Interrupter (GFCI).

• Operates at 120 V, 208 V, 240 V, 60 Hz.

• Switches on your heating system at predetermined times on
different days of the week.

• Offers 4 periods each day that you can set at different
temperatures.

• Comes with a preprogrammed schedule that is suitable for most
installations. However, you can customize this program any time
you wish.

• Allows you to reset the thermostat to factory settings.

• Changes the start time of a heating period automatically so that
the desired temperature is reached at the time that you set.

• Multiple temperature control options so users can control the
system based on floor temperature (F), ambient air temperature
(A), or both (AF).

• On/Off switch to turn off thermostat during summer months.

Installation

Important: This thermostat must be installed according to all

national and local electrical codes. The installation must be
performed by qualified personnel.

Locating the floor temperature sensor

The floor temperature sensor is installed under the floor surface.
See the QuickNet System Installation Manual (H57704), Section
6, for more details. Perform the Sensor Resistance Test prior to
terminating the floor sensor to the thermostat. See the QuickNet
System Installation Manual (H57704), Section 7, for more details.

Wiring the thermostat

WARNING: Turn off the power to the circuit at the main

power panel to avoid electric shock.

WARNING: Shock hazard. To prevent shock, the QuickNet

floor heating mat must be connected to ground.

1. Remove the control module from the power base by loosening
the captive screw underneath the base.

2. Connect the floor heating cold leads to the load wires (two
inner wires) using the sup­plied wire nuts.

3. Connect the power supply
leads to the power base wires

4. Connect the floor heating cold
lead braid (ground) to the
supply ground in the electrical
junction box.

8. Verify the settings of the configuration switches on the back
of the control module. Default settings for the configuration
switches are highlighted below.

Important: If your system is installed underneath laminate
or engineered wood flooring, you MUST use AF mode with the
default settings. Note the factory default is AF mode.

function is enabled, the thermostat calculates the optimal time
to start heating in order to obtain the desired temperature by the
set time. The thermostat re-assesses the start time daily based
on the previous day’s results.

Note: If you wish to use only 2 periods, set periods “1 and 4”
or periods “2 and 3”. Early Start will not work if you set periods
“1 and 2” or periods “3 and 4”.

To select floor sensing mode, place the switch to the F position.
To select floor sensing and ambient sensing mode, place the
switch to the AF position and ensure that the remote tempera­ture sensor is connected to the thermostat. To select the A
mode, place the switch in the AF position and ensure that the
remote temperature sensor is NOT connected to the thermostat.

9. Install the control module onto the power base.

Ground-Fault Protection

The QuickStat-TC has a built-in GFCI (5 mA trip level). This

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
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
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.
