MASTER THERMOSTAT

If a mat or cable system requires more than 15 amps, we recommend installing SunStat Relays.

SunTouch’s new SunStat Relays System is specially designed for large floor heating applications exceeding 15 amps. Here’s how it works:

Relays connect directly to SunStat thermostats for simple, elegant control of larger system

SunStat Relays don’t require a special “master thermostat”, as before with the older version, this new Relays are dual voltage 120 VAC or 240 VAC, have a 15-amp capacity, and on/off switch and GFCI and test light.

It’s possible to control over 1500 sq. ft. of electric floor warming using 120 VAC and cover 3,000 VAC sq. ft floor warming mats or cables.

SunStat Relay

Programmable and Non-programmable models available
Controls up to 10 slave units (120vac & 240vac)
Low voltage wiring means SunStat Relay can be installed anywhere
Silent operation

The new SunStat Relays System is specially designed for large floor heating applications exceeding 15 amps. Here’s how it works:

First, find the amp draw for each SunStat, UnderFloor or Warm Wire product on our web site, or on our more information section, then determine how many can connect to each relay. Up to ten 15-amp Relays can connect to one SunStat.

Ten Relays. Plus the internal relay in the SunStat, provide a total capacity of 165 amps! Each Relay should be connected to individual 20 amp breakers, as shown in this page picture

SLAVE UNIT

The Slave Unit with a built-in GFCI is controlled by a SunStat to heat

part of a large area..

Ground Fault Circuit Interrupter (GFCI)

Slave Unit models meet UL and CSA standards for Class A GFCIs.
Slave Unit models cut power to the heating system when a 5mA leak is detected.
