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.
For warm water heating systems
•
on thermostatic radiator valve bodies, or
•
on compact radiator valve inserts.
