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. 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).

•A 3-wire 20 AWG cable is recommended.

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 con- nectors for copper wires, and secure the base to the electrical box.

oAffix the wiring sticker (in the CT230

p Connect the slave power bases

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).

rSwitch 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).
