THERMOSTAT WITH REMOTE SENSOR FOR WATER AND AIR

Design

The radiator thermostat consists of:
• Housing with lid and socket
• M30 x 1.5 connection and 11.5 mm closing dimension
• Liquid-filled sensing element with capillary tube (length 2m)
• Capillary tube
• Connection nut

Materials

• Handwheel and lid made of plastic, white to RAL9010
• Socket made of black plastic
• Support cage and spindle construction made of plastic
• Liquid-filled copper sensor phial with nickel-plated copper 

capillary tube

• Connection nut made of nickel-plated brass

Application

Thermostats of this type are proportional controller without 
external energy requirement for the temperature-dependent 
control of warm air heaters, hot water generators, heat ex-
changers, etc. The remote sensor is directly immersed into the 
medium. Alternatively a sensor immersion pocket is available 
separately as an accessory.
Thermostats of this type with M30 x 1.5 connection are suitable 
for all Honeywell TRV bodies and radiator inserts, all Honey-
well valve series M, as well as other TRV bodies and radiator 
inserts with M30 x 1.5 connection and 11.5 mm closing dimen-
sion.

Features

• Liquid-filled sensing element
• Memory-clip
• Equipped with concealed limiting and blocking tabs

Specifications

NOTE: P-bands given in the flow diagrams of thermostatic 

valves have to be multiplied with two when the valves 

are used with the 2080WL.

Example: kv-value 0.45 at 2K P-band for use with a 

normal thermostat changes to kv-value 0.45 at 4K 

P-band for use with the 2080WL.

Function

Thermostats of this type control the TRV body. The medium 
passing around the sensor of the thermostat causes the sensor 
to expand when the temperatur rises. The sensor acts onto the 
valve spindle and this causes the TRV to close. When the 
temperature falls the sensor contracts and the spring-loaded 
valve spindle is opened. The TRV opens in proportion to the 
temperature of the sensor. Only the amount of water required 
to maintain the temperature set on the thermostat can flow 
through the valve.
