The following cautions must be observed:
Warning
To prevent the risk of personal injury and/or death, make sure power is not applied to the product until it is fully installed and ready for final testing. All work must be done with power turned off to the circuit being worked on. To reduce the risk of electric shock, do not connect to a circuit operating at more than 150 V to ground.
Pull power supply wiring to the relay location.
Warning
Make sure 120 VAC is supplied to 120 VAC cables and 240 VAC is supplied to 240 VAC cables. Otherwise, dangerous overheating and a fire hazard could result. Do not exceed 15-amps on this control.
Floor Heating Mat or Cable Power Lead Installation
Rough-in Communication Wiring
Relay C3 Wiring
Before connecting the wires to the back of the relay, detach the front from the base. While holding the base section in one hand, pull the lower half of the front towards you to pivot it away from the base.
Using the wire nuts included with the relay:
Connection to the SunStat thermostat and additional relays are made by inserting the wires into the square openings in the terminal block and tightening the screws on the side.
Warning
Make sure the wire connections are secure by gently tugging on them. Otherwise, arcing could occur, causing dangerous overheating and a possible fire hazard. For added security, overwrap each wire nut connection with electrical tape.
Notice
Make sure the mortar has had time to fully cure before operating the system for more than a brief test.
LED lights on the SunStat Relay C3 indicate operational status.
Power Up
Heating Operation
The SunStat Relay C3 provides additional capacity for spaces that are larger than a SunStat Connect, Command or Core thermostat can control. The SunStat Relay C3 energizes the connected heating cable any time the thermostat determines heat is required. When the thermostat signals the relay to operate, the Heat Demand light is on.
GFCI Testing and GFCI Light Operation
Power Off
It is strongly recommended that a qualified, licensed electrician install the heating cables and related electrical components. If problems with the system arise, please consult the troubleshooting
guide below.
Warning
Any electrical troubleshooting work should be performed with the power removed from the circuit, unless otherwise noted.
