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