Room Operating Units/Controller


The JOY room thermostat with its high-grade materials, such as a real glass surface, is designed for individual temperature control in living spaces, hotel rooms and offices. The heating/cooling valves are controlled either by relay contacts or 0..10 V signals. 6-way valves can also be controlled with the JOY HC. This ensures individual and energy-efficient room air conditioning. The JOY (available in black or white) has an intgerated display and touch-sensitive buttons. Furthermore, the integrated scheduler can handle 3 time channels and 4 periods each. The device is designed for mounting in a flush-mounted box.
