7.1 Requirements for the electrician
Warning
Electric voltage!
Install the device only if you have the necessary electrical engineering knowledge and experience.
•Incorrect installation endangers your life and that of the user of the electrical system.
•Incorrect installation can cause serious damage to property, e.g. due to fire.
The minimum necessary expert knowledge and requirements for the installation are as follows:
•Apply the "five safety rules" (DIN VDE 0105, EN 50110):
1. Disconnect from power;
2. Secure against being re-connected;
3. Ensure there is no voltage;
4. Connect to earth and short-circuit;
5. Cover or barricade adjacent live parts.
•Use suitable personal protective clothing.
•Use only suitable tools and measuring devices.
•Check the supply network type (TN system, IT system, TT system) to secure the following
power supply conditions (classic connection to ground, protective earthing, necessary
additional measures, etc.).

Notes on commissioning
After the installation the accuracy of the switching point is established only after an operating
period of 1 to 2 hours.
For faster heating and alignment of the room temperature to the setpoint temperature, it is
recommended to initially set the temperature higher than required.
8.1 Calibrating the display of the actual temperature value (applies only to UTA devices)
To properly control loads larger than 2 A, the heating system must be connected for calibrating the display. After
the connection, the heating system is switched on automatically for about 20 minutes. During this time, the “CA”
symbol will be displayed. After this, the display adjusts itself to the room temperature within a few minutes.
Before repeating the calibration procedure, the unit must be disconnected from the power supply for at least 8
minutes.
8.2 Offset function

(scale correction)
Reaching the selected room temperature depends on the ambient conditions such as heating system capacity (at
least 5°K/h min.), room size, ambient temperature, insulation, etc. That is why the values in the scale are merely
guide values. To obtain a setting that is as accurate as possible, the adjusting knob can be offset in 4 stages by a
total of ±6°C as follows. Compare illustration 4:
1. Pull off the adjusting knob (3).
2. Cut the position lug (1) on the bottom side of the adjusting knob off with a suitable tool.
3. Re-attach the adjusting knob, which has been offset to the basic position with the desired correcting value.
