Low Volt Elec. Thermostat, Elec/Flr Heat


Low Volt (Floor and Ambient) Manual Thermostat for Electric heat

  • Product Info
  • Literature


The TH114 Series delivers the features that matter most in a non-programmable thermostat: an easy-to-read backlit display, slim contemporary design and precise temperature control.


  • Three choices of temperature control in a single thermostat (Ambient, Floor, or Ambient with Floor temperature limits)
  • 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
  • Backlit display
  • Battery-free
