Ammark: Control with Comfort

By modulating the flow of water or steam through the valve, the control portion of the TRV accurately maintains the output of each individual radiator, convector, or section of baseboard.  All Ammark controls fit all Ammark valve types as well as some other manufacturers' (see Adapters) and operate in any orientation.  Safe installation practice dictates that electric controls be mounted over the valve.

When using air-sensing controls, insure accurate temperature control by selecting control/ valve combinations which allow unrestricted flow of ambient room air around the sensor.
