Honeywell Thera-4 Classic (T3000 Series) Radiator Thermostat

A Radiator Thermostat is installed onto a Thermostatic Radiator Valve Body (TRV body). The combination of both, the Thermostatic Radiator Valve (TRV), controls the room temperature by adjusting the flow of hot water through a radiator.
TRVs are installed in water-based heating systems on the supply or, less commonly on the return connection of radiators.
Radiator thermostats of this type fulfill the European Standard EN 215 when used with certified Honeywell TRV bodies.
Honeywell radiator thermostats with Honeywell (HW) M30 x 1.5 connection are suitable for all TRV body and radiator inserts with M30 x 1.5 connection and 11.5 mm closing dimension.
Radiator Thermostats of this type with snapring (DA) type connection are suitable for TRV bodies and valve inserts with Danfoss (RA) type compatible snap connection.
For warm water heating systems
on thermostatic radiator valve bodies, or
on compact radiator valve inserts.
