Installation and connection
Observe all safety instructions!
• The thermostat features 4 terminals for
cable lugs; please refer to the imprint on the
bottom of the thermostat.
• If in doubt, have the installation and
connection done by an expert.
Mode of operation
• Within the capillary tube (and sensor tip), which is rmly connected to the
thermostat, there is a liquid that expands when heated. At the end of the capillary
tube inside the thermostat, there is a so-called pressure box that has been
preloaded mechanically via the adjustment shaft.
• A heating device activated via switch contact increases the temperature; the liquid
of the respectively installed sensor heats up while expanding at the same time.
• Once a certain temperature has been reached, the actuator on the pressure box
will interrupt the power circuit.
• The temperature will then drop, and the liquid inside the capillary tube contracts.
• Again, once a certain temperature has been reached, the power circuit will be
closed and the whole process starts from the beginning.
• The temperature, at which the thermostat interrupts the power circuit, can be
changed via the adjustment shaft.
• Since it is not an electronic control, this thermostat does not support the precise
selection of a certain temperature.
The switch contact allows for control towards heating and cooling,
depending which contact of the thermostat is used for the connection
(C + 2 or C + 1).
Disposal
At the end of its service life, dispose of the product in accordance with
applicable regulatory guidelines.
