Thera-4 Design

RADIATOR THERMOSTATS IN COMPACT SIZE

PRODUCT DATA

Application

Thermostats are installed onto thermostatic valve bodies (TRV bodies). The combination of thermostat and TRV body, (TRV), controls the room temperature by regulating the flow of heating water into a heat exchanger.

TRVs are installed in water-based heating systems at the supply or, less commonly at the return connection of radiators or other heat exchangers.

Thera-4 Design type thermostats conform to the European Standard EN215 when used with Honeywell TRV bodies according to table 2 on page 3.

Thera-4 Design with M30 x 1,5 connection are suitable for all Honeywell TRV bodies and radiator inserts as well as other TRV bodies and radiator inserts with M30 x 1,5 connection and 11,5 mm closing dimension.

Thera-4 Design-DA with Danfoss snap connection are suitable for TRV bodies and valve inserts with a Danfoss RA type compatible snap connection.
