HONEYWELL THERMOSTAT -Voltage 230V AC (commonly called 220V) system in the UAE to a low-voltage 24V AC smart thermostat requires specific conversion components and is a job best handled by a professional to ensure safety and compliance. You cannot directly connect a 24V thermostat to a 230V system.

Interface Relay kit or Contactor Module: Since the 24V thermostat cannot handle the high current of the AC unit's compressor and fan directly, you need a relay kit to act as a switch. The 24V signal from the thermostat activates the relay kit, which in turn safely switches the 230V power to the AC unit on or off.
