SunStat™ Relay (sub-control)
Model# 500680

If a mat or cable system requires more than 15 amps, we recommend installing SunStat Relays. Relays connect directly to SunStat thermostats for simple, elegant control of larger systems. Each SunStat Control (120 or 240 VAC) can accommodate up to 10 SunStat Relays.

It's possible to control up to 1,650 sq.ft. of electric floor warming using (1) 120 VAC SunStat Control and (10) 120 VAC SunStat Relays. Likewise, it is possible to control up to 3,300 sq.ft. using (1) 240VAC SunStat Control and (10) 240VAC SunStat Relays. This configuration can be used for SunTouch Mats, UnderFloor, and WarmWire products. Please see the SunTouch Installation Manual for information on sizing and installation requirements.
