Installation of solar controller

10.1

Appliance installation

The solar differential temperature controller is designed
to be mounted on the front of the hydraulic station.
Alternatively it can be removed from the insulation and
be wall mounted (see panel below). In the case of wall
mounting the pump cable may need to be lengthened.
Alternative mounting option
In the case of wall installation proceed in the
following way:
Drill installation holes according to the dimensions
shown below. Screw in two upper screws up to 6 mm
distance. Open the appliance as described in section
10.2 and hang it onto two screws. Now two lower
screws can be mounted.Tighten all screws. Do not
overtighten to avoid damage to the controller backplate.

Electrical connection overview

Always disconnect from the mains before opening
the controller cover. The electrical installation must
conform to all current Wiring Regulations and be carried
out by a competent electrician.
The connection of all electrical cables is to the terminal
block located on the backplate of the controller.The
terminals on the right side of the terminal block are for
extra low voltage connections (temperature sensors and
flow transmitters).The terminals on the left side of the
terminal block are for 230/240 V~ connections.
