RADIATOR THERMOSTATS

Application

A Radiator Thermostat is installed onto a Thermostatic Radiator Valve Body (TRV body). The combination of both, the Thermostatic Radiator Valve (TRV), controls the room temperature by adjusting the flow of hot water through a radiator.

TRVs are installed in water-based heating systems on the supply or, less commonly on the return connection of radiators.

Radiator thermostats of this type fulfill the European Standard EN 215 when used with certified Honeywell TRV bodies.

Honeywell radiator thermostats with Honeywell (HW) M30 x 1.5 connection are suitable for all TRV body and radiator inserts with M30 x 1.5 connection and 11.5 mm closing dimension.

Radiator Thermostats of this type with snapring (DA) type connection are suitable for TRV bodies and valve inserts with Danfoss (RA) type compatible snap connection.

Design

The radiator thermostat consists of:

• Handwheel with socket

• Honeywell HW M30 x 1.5 connection and 11.5 mm closing dimension or Danfoss snapring RA type connection

• Sensor with support cage

• Spindle assembly

• Connection nut

Materials

• Handwheel, lid and socket made of plastic, white to RAL9016

• Socket, support cage and spindle assembly made of plastic

• Sensor filled with liquid or wax

• Connection nut made of nickel-plated brass

Features

• Conforms with M30 x 1.5 connection to European standard EN 215

• Available with liquid- or wax sensor

• Equipped with easy to use range stoppers

• Modern ergonomical design

Specifications

Thermostat connection

Setpoint range 0 - ❄ - 1..5 (with zero-position)

Temperature range 1...26°C (34...79°F)(with zero-position)

Closing dimension 11.5 mm HW type

NOTE: Zero-position is also thermostatically controlled -

when temperature falls the TRV may open.

Snap connection DA type

❄ - 1..5 (without zero-position)

6...28°C (43...82°F)(without zero-position)

Function

Radiator thermostats of this type control the TRV body. The air passing around the sensor of the radiator thermostat causes the sensor to expand when the temperature rises. The expanding sensor closes the TRV accordingly. When the room temperature changes the TRV opens or closes proportionally. Only the amount of water required to maintain the room temperature set on the radiator thermostat is allowed to flow through the valve.

NOTE: All °C and °F-values approximate. Heating can freeze

when radiator thermostats with zero-position are set at position '0'. Zero-position is also thermostatically controlled - when temperature falls the TRV may open.

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
