Troubleshooting Guide

It is strongly recommended that a qualified, licensed electrician install the heating cables and related electrical

components. If problems with the system arise, please consult the troubleshooting guide below.

Make sure the mortar has had time to fully cure before operating the system for more than a brief test.

Any electrical troubleshooting work should be performed with the power removed from the circuit, unless

otherwise noted.

Operation

•

If the GFCI RESET light continues to flash after pressing

the RESET button, protection is lost, and the unit will need

replacement.

Power Up

• Switch on the circuit power supply at the breaker

• The Power Indicator will illuminate

If the GFCI trips during normal operation, press the RESET

button to resume operation. If it trips again, the floor heating

system should be inspected and tested by a qualified

electrician.

Heating Operation

The R4 Relay provides additional capacity for spaces

that are larger than a SunStat^®ConnectPlus thermostat

can control. The R4 Relay energizes the connected mat

or cable any time the thermostat determines that heat

is required. When the thermostat signals the relay to

operate, the Heating Indicator is illuminated.

•

If the GFCI TEST light stays on solid, a welded relay has

occurred, and the unit will need replacement.
