If the measured room temperature does not agree with the temperature set on the knob,
the temperature detector can be recalibrated.
This can be done by adjusting a potentiometer that is located on the rear of the unit.
First, the unit must be removed from the socket.
The possible settings on the potentiometer are:

After the corrections are made, the new setting must be confirmed by pressing the reset
button.
Otherwise the previous settings are still active!
After the reset the controller
can be remounted to the socket.
With the help of a suitable remote operation unit, the
controller
can be switched to the
economy temperature set for operating mode . Changeover takes place through the
making of a
potential-free contact
connected to terminals T1 and T2.
The LED indicates this by being light.
After the contact opens, the selected operating mode becomes active again.
