3.2 Slave Units - Installation and Wiring

1. Introduction

This master and slave unit system is specially

designed for large floor heating applications

exceeding 15 A.

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

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.

• 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 con-

nectors for copper wires, and secure

the base to the electrical box.

2. Operation

Master Thermostat

o Affix the wiring sticker (in the CT230

box) to the base.

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.

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

Slave Unit

The slave unit receives the signal sent by the

master unit and activates its load.

top of the power base.

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

NOTE: There must be a minimum of one slave

unit ON to power the master unit.

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 thermo-

stat and slave unit should not exceed 500 ft.

(150 m).

• The floor sensor cable should not exceed

200 ft. (60 m).

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).

• A 3-wire 20 AWG cable is recommended.
