Install Instructions

Phase 8 - Control Installation

STEP 8.1:

If it has not already been done, install an electrical box for the SunStat

thermostat and

SunStat Relay. See Step 2.2 for details.

STEP 8.2

Read and follow the instructions included with the SunStat thermostat and SunStat Relay

for complete connection instructions, requirements, and mounting.

STEP 8.3

Make any final connections to the circuit breaker or branch circuit source.

Refer to the installation sheets provided with the controls for proper setting. The system

should now operate as designed.

Please leave this instruction manual, SunStat Control

instructions, and copies of photos of the installed heating system with the end user.

Most laminate and wood floor manufacturers specify their flooring should not be subjected to

temperatures over 82° to 84°F (27° to 28°C). Check with the flooring dealer or manufacturer

and set the thermostat Floor Limit temperature appropriately.

Make sure 120 VAC is supplied to 120 VAC cables and 240 VAC is supplied to 240 VAC

cables. Otherwise, dangerous overheating and possible fire hazard can result.

STEP 8.4

System Start Up

After all controls are installed, do not energize the system, except to briefly test operation

of all components (no longer than 10 minutes). Do not put the system into full operation

until the tile or flooring installer verifies all cement materials are fully cured (typically

two to four weeks). See mortar manufacturer’s instructions for recommended curing time.

Please note, this installation manual is not a structural or a floor covering installation manual

and is intended only for general guidance as it applies to the SunTouch WarmWire product.

It is recommended to consult with professional flooring installers to make sure proper

materials are used and proper installation techniques are followed.

Phase 9 - Floor Coverings / General Recommendations

When installing tile or stone, the Tile Council of North America (TCNA) guidelines or ANSI

specifications should be followed as a minimum standard.

A latex-modified thin-set cement-based mortar and grout is recommended instead of

water-based multi-purpose materials when installing a radiant product.
