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.
