  • 5 mA ground fault circuit interrupter (GFCI) on GA models
  • 15 mA equipment ground fault protection devices (EGFPD) on GB models
  • GFCI and EGFPD test light verifies safety control is functioning properly and alerts if a leak is detected
  • Advanced temperature control ensures total comfort by minimizing temperature swings
  • ON/STANDBY switch enables thermostat shutdown at the end of heating season for added security
  • On-screen heating power indicator gives at-a-glance verification of power being used
