Description
Ideal for large floor heating setups exceeding 15 amps, the Honeywell/Resideo CT230‑GA (Aube slave unit) enables scalable installation of zoned floor heating systems. Paired with a single master thermostat, it simplifies electrical load distribution and enhances safety, zoning, and control across expansive heating zones.
Features:
- 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.
