• Page 2: Troubleshooting Guide It is strongly recommended that a qualified, licensed electrician install the heating cables and related electrical components. 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. If the GFCI RESET light continues to flash after pressing the RESET button, protection is lost, and the unit will need replacement. The R4 Relay provides additional capacity for spaces that are larger than a SunStat ConnectPlus thermostat can control. SunTouch warrants this control to be free from defect in material and workmanship for a period of three years from the date of original purchase. Press the TEST button on the GFCI monthly to verify that it is operational. This limited warranty does not cover shipping costs or a product subjected to misuse or accidental damage. If pressing TEST does not display a flashing red GFCI RESET light, protection is lost, and the unit will need replacement. To unpair the R4 Relay and reboot, press and hold the RESET button on the R4 Relay for 10 seconds.
