Installation and operation
Safety instructions
The controller has been built for the use at 230 Volt AC at a frequency of 50 Hz [or optional 115 V (±15 %), 60 Hz].
Using this controller for other V and Hz values is not allowed. Please also note that the admissible nominal currents
must not be exceeded.
If there is a grounded conductor planed or laid down for pump or reversing valve it MUST also be connected. There
are corresponding supply terminals. Please make sure that the earthing contact is led to the controller also on the
power supply side.
Wires that are not permanently connected with the building have to be equipped with a pull relief outside the
controller.
The controller is only for the prescribed applications. No liability is taken over for other utilization.
All operations on an open controller are only to be conducted cleared from the power supply. All safety regulations for
working on the power supply are valid. Connecting and/or all operations that require opening the controller are only
to be conducted by specialists.
The controller is protected against overload and short circuit.
5.1 Location of installation
The controller is designed for installation on vertical walls. It must not be installed in areas where you can find
flammable liquids or gases. It is only allowed to install the controller in areas in which the protective system
(paragraph 8. Technical data) is sufficient. The max. permissible ambient temperature at the place of installation must
never be exceeded or fallen below. Moreover, the controller must not be used in moist rooms (bathrooms) or in rooms
in which flammable gas mixtures (by gas bottles, paint, solvants etc.) are likely to occur!

5.2 Installation
Installation on walls
The upper controller cover (Illustration 3, Pos.
c
) protects the electronic system and must not be taken off.
First of all, fix screw 1 into the wall. The controller will be hung up on this screw afterwards (Illustration 3, Pos. d ). You
can use the controller as a stencil for the marking of the other 2 mounting holes. (Attention: Do not use the controller
as a stencil for drilling!)
After tightening the controller to the wall, you can start with the wiring.
