A 240V relay (AKA contactor) that allows you to control multiple circuits with a single thermostat control. It may be conveniently located inside an electrical junction box.
Please see wiring instructions in Installation section. Relays do not provide GFCI protection which is required for safety in most rooms. Thermostats DO provide GFCI protection, which is why multiple thermostats are typically a better option.
