RADIATOR THERMOSTATS WITH RED ECONOMY BUTTON

PRODUCT DATA

Application

Radiator thermostats are installed onto thermostatic valve

T100 M

bodies (TRV bodies). Together with a TRV body, for example the V100 M, they control the room temperature by regulating the flow of hot water into the heat exchanger. The temperature of different rooms is controlled individually and energy is saved.

The combination of radiator thermostat and TRV body is called 'Thermostatic Radiator Valve' or 'TRV'.

TRVs are installed in water-based heating systems at the supply or, less commonly at the return connection of radiators or other heat exchangers. With specially designed (normally closed) valves, radiator thermostats are sometimes also used in water-based cooling systems to control individual heat exchangers.

T100 M and T100 MF thermostats conform to the European Standard EN215. T100 M and MF type radiator thermostats are suitable for all Honeywell TRV bodies and radiator inserts as well as other TRV bodies and radiator inserts with M30 x 1.5 connection and 11,5 mm closing dimension.

Design

The radiator thermostats are made up of:

• Handwheel with lid, socket and red economy button

• T100 M with internal liquid- or wax-filled sensor with sup-

port cage

• T100 MF with external liquid-filled sensor, capillary tube

and housing

• Spindle assembly

• Connection nut

Materials

• Handwheel and lid made of plastic, white to RAL 9010

• Economy button made of red plastic

• Socket made of grey plastic

• Support cage and spindle assembly made of plastic

• Connection nut made of nickel-plated brass

Features

• Tested to the EN215 Part 1 European standard

• T100 M available with liquid- or wax-filled sensing

element

• Modern, ergonomical design with red economy button

for optimal setting

• Over temperature protection

• Patent-No. DE-PS 2 737 083

T100 M / T100 MF

Function

Thermostatic radiator valves enable individual control of room temperatures and thus save energy.

The radiator thermostat controls the TRV body. Air from the room passing over the sensor of the radiator thermostat causes the sensor to expand when the temperature rises.

EN215 Information

The sensor acts onto the valve spindle and this causes the TRV body 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 room temperature set on the radiator thermostat can flow into the radiator.
