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 EN215 when
used with certified Honeywell TRV bodies.
• Honeywell radiator thermostats with Honeywell (HW) M30x1.5 connection are suitable for all TRV
body and radiator inserts with M30x1.5 connection and 11.5mm 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.
