T3019 Thera-6

Radiator Thermostats

Compact thermostatic head with closed design and high energy efficiency

APPLICATION

Thermostatic radiator heads are self-actuating controllers which regulate the flow of hot water through thermostatic radiator valves to continuously control the room temperature to the set-point selected on the head.
The Thera-6 is a head with compact size, sleek design, energy efficiency and durability, which make it an ideal choice for residential heating applications.

4 Stem guide PA66 GF33
5 Over-temperature compensating spring Spring steel
6 Alignment sleeve PC

10 Handle ABS, white RAL 9016
11 Coupling nut Brass, nickel plated
12 Wall mounting bracket for bulb incl. attachment hardware (not shown) ABS, white RAL 9016

METHOD OF OPERATION

The thermal expansion element responds to room temperature by expanding or contracting proportionally.
The movement is transmitted onto the stem of the thermostatic valve, on which the head is mounted.
The head thus controls the amount of water which flows into the heat exchanger to just the flow required to maintain the room temperature set on the thermostat.
The temperature setpoint can be selected by rotating the handle, which changes the position of a backstop for the thermal expansion element.
In case of high room temperature and closed head, the expansion of the sensor is absorbed by the overstroke protection spring, protecting the valve and the sensor from an excessive force

TRANSPORTATION AND STORAGE

Keep parts in their original packaging and unpack them shortly before use.
The following parameters apply during transportation and storage:

Parameter Value
Min. ambient temperature: -20 °C
Max. ambient temperature: 50 °C
Min. ambient relative humidity: 25 %
Max. ambient relative humidity: 85 %

INSTALLATION GUIDELINES

Setup requirements
  • Mount the thermostat to the radiator valve with a torque of about 10 Nm
  • For heads with built-in sensor, horizontal orientation is recommended. Heads with built-in sensor should not be covered by curtains, hidden below a window sill or in a tight niche, which would prevent them from sensing the temperature in the room they should control
  • The Thera-6 heads with standard connection are compatible with all MNG, Honeywell and Honeywell Home thermostatic valves, as well as with Braukmann V100 thermostatic valves with M30x1,5 connection
  • When mounting the DA-type head onto a Danfoss RA valve, pull the coupling nut towards the head, snap the socket of the head onto the groove on the valve, and carefully thread the nut onto the thread of the socket. Then tighten the nut
  • Heads with standard connection can be mounted on thermostatic valves with M30x1.5 threaded connection from some other remanufacturers, including Heimeier, Oventrop or Rossweiner. However, because the closing dimension (valve stem height when valve is closed) varies slightly among the manufacturers, the temperature to which the head will regulate may be shifted by a few degrees. The Thera-6 heads have an interface at another depth for the Braukmann V100 valves with ø3mm axis. Therefore, valves of other manufacturers with axis diameter less than ø4mm are not suitable for use with the Thera-6, as the valve axis will sink into the second interface depth of the head.
  • When installing heads with remote sensors, handle the capillary with care to prevent damage to its soldered connections, and avoid sharp bends of the capillary which would obstruct free movement of the expansion liquid.
