Description

The Milesight WT211 is a LoRaWAN smart thermostat and HVAC controller for most 24VAC heating and cooling systems - heat pumps, air conditioners (2H/2C), heat pumps (4H/2C or 3H/2C + 1-stage AUX), boilers, furnaces and PTAC. Its high-current relays (up to 3 A per channel, 5 A total) drive more demanding equipment than the standard WT201.

A 4.2-inch LCD shows room temperature, humidity and status, while a built-in temperature/humidity sensor enables accurate control. With heat/cool/auto and fan modes, 7 working modes and up to 16 schedules each, it offers precise comfort control - and integrates with hotel key-card systems, BACnet (via Milesight gateways), Milesight D2D and the Development Platform.
