5. INSTALLATION AND ELECTRIC CONNECTIONS

5.1. C
ONTROLLER
The Heating Controller can be installed directly on a solid base (e.g. a wall). For this purpose the front panel of the
Controller must be removed (fig. 4a) and the back section should be fastened using appropriate screws and pins
(these are not included in the scope of supply) (fig. 4b). Using a knife, remove the protection film before inserting
the upper fastening screw.
If the Controller has been factory fitted with cables for connecting to a pump, valve drive, temperature limiter, sen-
sors etc., take care not to damage or crack the cables during the installation. Furthermore these cables should not
subjected to any tensile stress during installation. The cables will be fixed by means of the device for strain relief at
the heating controller.
If the Heating Controller is delivered together with a hydraulic control unit (for example FRG or FlowBox) and if it is
not attached to that unit by any installation plate or support, it should be installed next to that unit.
Pay attention to the correct connection of the cables if the Controller is not installed directly on a hydraulic control
unit but at some other place for the reason of better access.
Refer to the directions about this in section 5.2 Electric connections.
After making the electric connections, refit the front panel. (fig. 4с).

LECTRIC CONNECTIONS
All electric connections must be made by an authorized specialist according to the local regulations on electric
installations. The electrical cables must not come into contact with any hot components.
Optional connection – temperature limitter TB
(option).
The connection is factory fitted with a cable bridge. It must be
removed if connecting TB.
