2080WL

THERMOSTAT WITH REMOTE SENSOR FOR WATER AND AIR

PRODUCT DATA

Application

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

Thermostats of this type are proportional controller without external energy requirement for the temperature-dependent control of warm air heaters, hot water generators, heat exchangers, 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 Honeywell valve series M, as well as other TRV bodies and radiator inserts with M30 x 1.5 connection and 11.5 mm closing dimension.

Features

•Liquid-filled sensing element

•Memory-clip

•Equipped with concealed limiting and blocking tabs

Specifications

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: 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.
