Honeywell MV100 Electric Controllers T100, T200 Thermostatic Controllers and V2000 Radiator Valves

Honeywell MV100 Electric Controllers T100 Product Data

Honeywell MV100 Electric APPLICATION

The MV100, T100, T200 Controllers, when paired with V2000 Radiator Valves, provide automatic temperature control by modulating the flow of steam or hot water through freestanding radiators, convectors, and other heating units. They provide comfort and energy savings at affordable prices.

Honeywell MV100 Electric FEATURES

Continually monitors and adjusts room temperature for consistent comfort and relief from underheating and overheating.
T100,T200 Controllers include sensor, setpoint dial and valve actuator; components can be integral or connected by capillary tubing.
T100,T200 Controllers require no electrical connections.
T100A,F,M models have range limiting features to limit adjustment or lock at a fixed setting (can require limit pin accessory).
EPDM valve seat disk assures tight shutoff on steam and hot water systems.
Nickel-plated bronze cast valve body.
Cartridge containing all working parts inserts into valve body for ease of service.
Cartridges are replaceable while valves remain in service and under pressurE (WITH accessory service tool MT100C).
Valves remain normally open with no control mounted.
Valves can be used with T100, T200 Thermostatic or MV100 Electric Controllers.
