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.
Operating temperature max. 130°C (266°F)
Differential pressure max. 0.3...1 bar (4.4...14.5 psi),
dependent upon used TRV body
Thermostat connection M30 x 1.5
Setpoint range 2..7
Temperature range 20...70°C (68...158°F)
at nominal flow rate
Closing dimension 11.5 mm

NOTE: All °C and °F-values approximate.
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 require-
ments or needs
