This system is specially designed for large floor heating applications exceeding 15A.


  • Here's how it works
  • A floor heating area exceeding 15A is separated into zones, with a linked unit responsible for heating each zone.
  • All linked units are controlled by a master thermostat responsible for settings/programming of the entire floor.
  • No settings dial. Settings controlled by master means units can be installed anywhere
  • ON/STANBY switch enables unit's heating area to be shut down independently of other heating areas
  • Built-in GFCI/EGFPD with test light. No need to buy separate safety cutoff.
