Equicalor™ is a wireless system for zoning hydronic and two-pipe steam radiators, which uses standard or rechargeable AA batteries. The system consists of one or more controllers and one or more transceiver- actuators, installed on each radiator’s thermostatic valve instead of a mechanical head. The controller can be programmed by the user on a 24/7 basis, and controls the ambient temperature in each room for comfort (T1), energy savings (T2), and frost protection (T3).

The transceiver allows the user to set different temperatures for each room.  It sends data wirelessly to the controller, which then determines what action is necessary to maintain the programmed heating parameters for that zone and relays that information back to the transceiver.
