Installation And Connection; Operating Principle; Technical Data - BASETech 1462511 Bedienungsanleitung

• If it can be assumed that safe operation is no longer possible, the product must be
turned off and precautions must be taken to ensure that it is not used unintentio-
nally. Do not touch the product.
First switch off the mains voltage to all poles (switch off the connected circuit
breaker or remove the fuse and then switch off the connected RCD).
After this, arrange for a skilled electrician to check the product.
• Safe operation can no longer be assumed if:
- the product shows visible signs of damage
- the product does not work at all or well (flickering light, leaking smoke or a
smell of burning, the light flickers, audible cracking noises, discolouration to the
product or the adjacent surfaces.)
- the product was stored under unfavourable conditions

Installation and connection

Please observe the chapter "Safety instructions"! If in doubt, let a specialist do the
installation and connection.
• Remove the rotary knob. After that remove the retaining ring (undo the two screws), remem-
ber the correct orientation!
• Mount the thermostat at the desired location. Fix the thermostat to the retaining ring. Fit on
the knob again properly.
• W hen laying out the capillary tube, make sure that it is not damaged by sharp edges.
• Mount the sensor so it is securely attached. In order to achieve optimum thermal conduction,
apply thermal grease between the sensor and the surface to be measured as necessary. Do
not damage the sensor!
• The thermostat is equipped with 3 connections for cable lugs; for this, also observe the
overprint of the wiring diagram on the underside of the thermostat.

Operating Principle

In the long capillary tube (and the sensor tip), which is permanently connected to the thermo-
stat, there is a liquid that expands upon warming. At the end of the capillary tube in the ther-
mostat there is a pressure sensor, which is mechanically preloaded by the adjustment spindle.
A heating device, which is activated via the switch contact, increases the temperature; the liquid
in the installed sensor warms up and expands.
The control element of the pressure sensor breaks the circuit when it reaches a given tempe-
rature.
The temperature falls again and the liquid in the capillary tube contracts.
At a given temperature, the circuit closes again and the process is repeated.
The temperature at which the thermostat breaks the circuit can be adjusted using the adjust-
ment spindle.
Since this is not an electronic control, it is not possible to set the thermostat exactly to a specific
temperature.
The switch contact allows control of both cooling and heating, depending which
thermostat contacts are used to make the connection (P1 + 2 or P1 + 1).
Disposal
Electronic devices are recyclable material and do not belong in the household was-
te. Dispose of an unserviceable product in accordance with the relevant statutory
regulations.
