1. Introduction

This master and slave unit system is specially
designed for large floor heating applications
exceeding 15 A.
The master thermostat controls a single or
multiple floor heating zones driven by slave units.
The master thermostat can control up to 10 slave
units.
Each slave unit drives its own zone and is
equipped with a GFCI test button and warning
light as well as an On/Standby switch to facilitate
maintenance on specific zones of the floor
installation.

2. Operation

Master Thermostat

The master unit controls the temperature and
sends a signal to slave units when heating is
required. The floor sensor is connected to the
master unit. The master unit is powered by the
slave units.

Slave Unit

The slave unit receives the signal sent by the
master unit and activates its load.

NOTE: There must be a minimum of one slave
unit ON to power the master unit.

3.2 Slave Units - Installation and Wiring

The slave units can operate on different voltages (e.g. 5 units @ 120 V and 5 @ 240 V).

• Required parts: CT230-120GA, -120GB, -240GA or -240GB

• Installation: On an electrical box

• Location: Installation near the master

thermostat is not required (i.e. can be
installed in a utility room).

• Wiring: The power bases are joined

through a daisy chain connection.

n Connect the 120 V or 240 V power

base wires to the power (line) and to
the load (floor) using solderless con­nectors for copper wires, and secure
the base to the electrical box.

o Affix the wiring sticker (in the CT230

box) to the base.

p Connect the slave power bases

together as per FIGURE 1.

q Once installation and wiring is com-

plete, mount the CT230 interface:
a) Align the bracket tabs of the

CT230 with the holes located on
top of the power base.

b) Secure the CT230 interface using the screw (captive).

3. Installation

Turn off power to the heating system at the
main power panel to avoid electrical shock.

Installation should be carried out by an
electrician.

3.1 Wiring Guidelines

• The wire distance between the master thermo­stat and slave unit should not exceed 500 ft.
(150 m).

• The floor sensor cable should not exceed
200 ft. (60 m).

• A 3-wire 20 AWG cable is recommended.

Connections

r Switch all slave power bases to STANDBY by sliding the protective door upwards

and positioning the switch to STANDBY.
Install and connect the master unit (see 3.3).

3.3 Master Thermostat - Installation and Wiring

WARNING: Make sure all slave units are in STANDBY mode.

•Required parts: TH113-A/F/AF (12VDC),

TH114-A/F/AF (12VDC),
TH115-A/F/AF (12VDC) or
TH116-A/F/AF (12VDC)

• Location: anywhere easily accessible to users.

Temperature control: AF (ambient with floor limit) / A (ambient)

• Install the master thermostat in the controlled area.

• Choose a location about 5 ft. above the floor in an area where the tempera­ture is stable.

• Avoid locations where there are air drafts (top of staircase, air outlet), dead air
spots (behind a door), direct sunlight or concealed chimneys or stove pipes.

Temperature control: F (floor)

• Can be installed anywhere.

s Wire the 12 VDC base to the nearest slave unit.

The floor sensor must be installed in an area where average temperature can be
read. The cable must follow the wall down to the floor and must not cross any
heater wires or be directly on or adjacent to a heating wire.
For maximum performance, the sensor probe should be centered between the
wires in the mat (max. 80°C).

t Push the excess wire into the wall, secure the base using the provided screws

and wall anchors, and install the TH11x thermostat onto the base.

u Once the thermostat is installed, return power to heating system and switch all

slave units and the master thermostat to ON.

3.4 Slave Units - GFCI Test

We recommend you test the GFCI immediately after installing the thermostat, and
once a month thereafter to ensure it is operating properly.

If the test warning light comes ON during normal operation, cut power to heating
system from the main power panel and verify the installation.

n Slide the protective door upwards and make sure the switch is ON.
o Press TEST.

• The test is successful if the TEST warning light is ON and power is cut off.

• If the test fails (first installation test):

a. Verify installation
b. Check the load wires
c. Once you've identified the problem, run the GFCI test again

• If the test fails (monthly maintenance):

a. Cut power to heating system from the main power panel and call customer

service

p When the test is successful, reset the slave unit by switching from ON to

STANDBY then back to ON.

q Repeat steps 1 to 3 for all slave units.
