.2 Slave Units - Installation and Wiring  
1
. Introduction  
The slave units can operate on different voltages (e.g. 5 units @ 120 V and 5 @ 240 V).  
This master and slave unit system is specially  
designed for large floor heating applications  
exceeding 15 A.  
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  
o Affix the wiring sticker (in the CT230  
Master Thermostat  
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  
00 ft. (60 m).  
A 3-wire 20 AWG cable is recommended.  
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).

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).
