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

Setpoint

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
