6.6 Solar Thermal
It may be part of the system design to incorporate solar thermal.
This is easily done with the use of an additional two-pole relay.
This can, of course be added to both monovalent and bivalent systems. It
is much easier to carry out all these types of systems based on S-plan type
controls only.
6.7 Connection of Heating System Controls
For information relating to the connection of the heating system controls, refer
to Figures 6-8 or 6-9.
6.8 Connection of Display Pad
For information relating to the connection of the display pad, refer to Section

Tightening torques
M4 screw 1.2 to 1.8 N m (12 to 18 kgf cm)

It is important that the cable is stripped back
10mm.

terminal screws to the specified torques, other-
wise, overheating may occur and possibly cause
