Installation Guide

Review

In addition to the features for the Non-programmable SunStat, the Programmable SunStat has a built-in seven day timer function to turn the system on when you desire and to turn it off when you leave home.
Many people believe the extra cost can quickly be recovered in energy savings by using this electric radiant floor heat control.

Dual Voltege for both 120 VAC and 240 VAC
Features include a floor sensor that directly senses floor temperature, 15-amp capacity controlling up to 150 sq. ft. of 120-VAC mats or 300 sq. ft. of 240-VAC mats; built-in ground fault protection with no need for a separate GFCI (in most code areas) large, back-lit digital display temperature range of 40° to 104°F.
Temperature display in °F or °C; on/off switch; 12 or 24-hr. clock.

Specifications - 500670

Material

• One (1) power base
• Two (2) 6-32 screws 1-1/4 in.
• Four (4) solderless connectors for copper wires
NOTE: Special CO/ALR solderless connectors must be used when connecting with aluminum conductors.
• One (1) temperature sensor with a 15-ft. (4.5-meter) extension
• One (1) flat-tip screwdriver.

Installation Guidelines

• High voltage SunStat must be installed onto an electrical box.
• For a new installation, choose a location about 5 ft. (approximately 1.5 meters) above the floor, with good air circulation.
• The SunStat must be installed facing the heating system.
• The SunrStat must be installed on an inside wall.
• Avoid locations where there are air drafts (top of staircase, air outlet), dead air spots (behind a door), direct sunlight or concealed chimneys or stove pipes.

Installation Steps

The GFCI monitors electricity flow for any loss of current; if there is, the SunStat immediately cuts power to the heating system.
We recommend you test the GFCI right after installing the control module, and once a month thereafter to ensure it is operating properly. To test

1. Press the TEST button:
• Successful: Test warning light is ON and power to heating system is cut-off.
• Unsuccessful: Test warning light is OFF.
Cut power to heating system from the main power panel and call technical service.
2. When successful, reset SunrStat (On/Standby) to power the heating system.
NOTE: If the warning light comes on during normal operation, cut power to heating system from the main power panel and have an electrician verify the installation.

Specifications - 500680 Relay Control

FEATURES

• Convenience: controls up to 10 slave units from a single master thermostat. Each Slave Unit can handle up to 15 amps.
• Controls slave units operating on different line voltages.
• Versatility: works with programmable and non-programmable models.
• Floor sensor enables precise control of floor temperature.
• Advanced temperature control ensures total comfort by minimizing temperature variations.
• Battery free.

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
