USAGE
The electronic temperature and humidity regulators are used to switch heaters, cooling equipment, filter fans or signal devices on or off if the temperature or humidity value rises above or falls below an adjustable or preset reference value. The controllers must only be used in stationary, sealed housings for electrical devices. There is a default response delay of approximately 5 sec. The external sensor with cable can detect the temperature decentrally (observe temperature range!).
Versions
- Internal temperature and humidity sensor
- External temperature and humidity sensor
Safety considerations
- Installation must only be performed by qualified electrical technicians in observation of the respective national power-supply guidelines (IEC 60364).
- The safety measures according to VDE 0100 are to be ensured.
- The technical specifications on the type plate must be strictly observed!
- No changes or modifications must be made to the device.
- In case of apparent damage or malfunction, the device may not be repaired or put into operation. (Dispose of device.)
Installation guidelines
-
The regulator should be installed in the upper area of the electric cabinet as far as possible from heaters or other heat-generating
components. -
Alternatively, the external sensor enables the detection of heat/humidity far from the regulator.
-
The device must not be covered.
-
The device must not be operated in environments with aggressive atmospheres.
-
The device is to be installed vertically, i.e. with the connection terminals at the bottom.
-
Mode of operation: 1.C
-
Degree of contamination: 2
-
Rated impulse voltage: 4kV
Humidity function
If the relative humidity exceeds the value set on the humidity dial, the
electric circuit is closed via terminals 5-3. LED illuminates.
Temperature function
If the ambient temperature drops below the value set on the temperature dial,
the electric circuit is closed via terminals 5-3. LED illuminates. If the
ambient temperature rises above the value set on the temperature dial, the
electric circuit is opened via terminals 5-3.
Notice
The manufacturer accepts no liability in the case of failure to observe this
brief instruction, improper use, and changes or damage to the device.
