Safety Preventing risks of fatal injury from electric shocks • Make sure that all regulations applicable at the point of use are complied with. • Always make sure that the controller is disconnected from the power supply before carrying out any work on it. •...
Description of the controller • When in "manual mode", the system must only ever be operated for a short time and only for test purposes. • Install sensor lines separately from 230 V lines. • Use only sensor connection boxes supplied by the manufacturer. 2 Description of the controller The controller is used for monitoring and controlling a heating system.
Installing the controller For data exchange purposes the controller is equipped with a microSD card interface (1). 3 Installing the controller DANGER Risk of fatal injuries due to explosions or fire. Never use the controller in areas where there is a risk of explosion. Install the controller on a non-flammable subsurface.
Installing the controller 3.1 Fastening the controller If you wish to lead cables and lines through the back of the controller, you need to do this before you fasten it. ATTENTION Risk of damage to the controller housing due to screws tightened too firmly.
Connecting the controller 4 Connecting the controller DANGER Risk of fatal electric shock when working on the opened controller. Make sure that the controller is disconnected from the mains voltage before removing the terminal cover. Make sure that the power supply has been secured to prevent it from being switched on again.

Connecting the controller The following illustration shows the elements of the controller that are important for connection: Pos. Description Terminals for extra-low voltage area Fuse Terminals for 230 V area Terminals for protective conductor Terminals for relay contact Cut-out apertures for cable feedthrough at the back Screw clamps for securing the cables Cut-out apertures for cable feedthrough on the underside Connect the cables to the corresponding terminals.
Connecting the controller 4.2 Connecting the controller to the power supply When making the mains connection, you must ensure that the mains supply can be disconnected at any time. If you make a permanent mains connection, proceed as follows: Install a switch on the supply lead of the controller. If you make the mains connection complete with cable and earthing pin plug, proceed as follows: Make sure that the earthing pin plug is easily accessible.
Connecting the controller 4.4 Assignment of the terminals to the system components For orientation when assigning the terminals to the switching outputs, various different system layouts are shown in the document Hydraulic layouts. These show simplified solar circuits that you can use with the controller. The process water circuit is not shown here. For the hydraulic layouts you can select "External heat exchanger"...
