SunTouch Mats, including design considerations, installation steps, limitations, precautions, and floor covering guidelines.
Specifications for SunTouch Mat:
SunTouch Mat is a complete heating mat consisting of a series
heating wire and a power lead for connection to the electric
power supply. The heating wire length cannot be cut to fit.
Controls: SunTouch Mats must be controlled by a SunStat®
floor sensing thermostat.
Voltage: 120 VAC, 240 VAC, 1-phase (see Table 2)
Watts: 12 W/sqft (41 Btu/h/sqft)
Maximum circuit load: 15 A
Maximum circuit overload protection: 20 A breaker
GFCI: (Ground Fault Circuit Interrupter) required for each
circuit (included in the SunStat control)
Listing: UL Listed for U.S. and Canada under UL 1693 and
CAN/CSA C22.2 No. 130-03, File No. E185866
Application: Type (X) (See UL Name Plate Label on product)
For indoor floor heating application only. Only embedded in polymer modified cement based mortar . UL Listed to U.S.
Standards only for installation into a shower area. (See 4.10 for details).
Minimum bend radius: 1 inch
Maximum exposure temperature: (Continuous and storage) 194ºF (90ºC)
Minimum installation temperature: 50ºF (10ºC)
Skill Level
Installation must be performed by qualified persons, in accordance with local codes, ANSI/NFPA 70 (NEC Article 424) and CEC Part
1 Section 62 where applicable.
Prior to installation please consult the local codes in order to understand what is acceptable. To the extent this information is not
consistent with local codes, the local codes should be followed. However, electrical wiring is required from a circuit breaker or
other electrical circuit to the control. It is recommended that an electrician perform these installation steps. Please be aware local
codes may require this product and/or the control to be installed by an electrician.
Expected floor temperature
Heating performance is never guaranteed. SunTouch Mat is designed to deliver 12 W/sq.ft. The floor temperature attainable is
dependent on how well the floor is insulated, the temperature of the floor before start up, and the overall thermal drain of the
floor mass. Insulation is required for best performance. Refer to Phase 5 for important design considerations.
You are required to thoroughly read all installation instructions and product safety information before beginning the installation
of this product. FAILURE TO COMPLY WITH PROPER INSTALLATION AND MAINTENANCE INSTRUCTIONS COULD RESULT IN
PROPERTY DAMAGE, PERSONAL INJURY AND/OR DEATH. Watts Radiant is not responsible for damages resulting from improper
installation and/or maintenance.
