HEAVY-DUTY RADIATOR THERMOSTAT
Application
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.
Features
• Conforms with M30 x 1.5 connection to European standard EN 215
• Equipped with liquid sensor
• Memory-clip
• Easy to equip with range stoppers
Design
The radiator thermostat consists of:
• Handwheel with lid and socket
• Honeywell HW M30 x 1.5 connection and 11.5 mm closing
dimension
• Sensor with support cage
• Internal or remote sensor
• Liquid sensor
• Spindle assembly
• Connection nut
Materials
• Handwheel socket and lid made of plastic, white to RAL9016
• Socket made of black plastic
• Socket, support cage and spindle assembly made of plastic
• Sensor filled with liquid
• Connection nut made of nickel-plated brass

Function
Radiator thermostats of this type control the TRV body. The air
passing around the sensor of the radiator thermostat causes
the sensor to expand when the temperature rises. The
expanding sensor closes the TRV accordingly. When the room
temperature changes the TRV opens or closes proportionally.
Only the amount of water required to maintain the room temperature set on the radiator thermostat is allowed to flow through
the valve.

NOTE: All °C and °F-values approximate. Heating can freeze
when radiator thermostats with zero-position are set
at position '0'. Zero-position is also thermostatically
controlled - when temperature falls the TRV may
open.
Please Note:
• To avoid stone deposit and corrosion the composition of the
medium should conform with VDI-Guideline 2035
• Additives have to be suitable for EPDM sealings
• System has to be flushed thoroughly before initial operation
with all valves fully open
• Any complaints or costs resulting from non-compliance with
above rules will not be accepted by Honeywell
• Please contact us if you should have any special requirements or needs
