## Long description

Engo heating control kit E25-BATW-4 + ETRV-M30 is a wireless thermostat set in white designed for room temperature regulation and zone control of hydronic heating systems. The kit combines a compact battery-powered room thermostat and a valve-mounted electronic TRV to provide scheduled temperature control for individual radiators or heating zones. It is suitable for retrofitting existing radiator valves or for use in systems where wireless communication between room controller and valve actuator simplifies installation.
Advantages
The kit offers a combination of a programmable, battery-powered room thermostat and an electronically controlled thermostatic radiator valve, enabling independent zone control without the need for new wiring. Wireless communication reduces installation complexity and allows the thermostat to be positioned for optimal temperature sensing. The compact white design integrates with typical interior environments and the valve-mounted actuator provides precise modulation of radiator flow to maintain set temperatures.
Suitable for

How to use
Mount the electronic TRV onto the radiator valve following the valve manufacturer’s mechanical compatibility requirements. Install batteries in the room thermostat and place it in a representative location away from direct sunlight, drafts and heat sources for accurate temperature sensing. Pair the thermostat with the valve actuator by following the wireless pairing procedure provided in the product manual. Program desired temperature setpoints and schedules on the room thermostat to control heating periods and maintain comfort in the selected zone.
Usage recommendations
