6.5 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.
Y and W type plans can be used, but the need for additional relays
is not practical. It is much easier to convert Y and W type plans to S
types from the start.
6.6 Connection of Heating System Controls
For information relating to the connection of the heating system
controls, refer to Figures 6-8 or 6-9.
6.7 Connection of Remote Controller
For information relating to the connection of the remote controller,
refer to Section 7.
6.8 Wiring Diagrams
To view the heat pump wiring diagrams, refer to Appendix B (wiring
diagrams).
6.4 Tightening Torques
Table 6-7: Tightening torques
Tightening torques
M4 screw 1.2 to 1.8 N m (12 to 18 kgf cm)
M5 screw 2.0 to 3.0 N m (20 to 30 kgf cm)
When using crimp type terminals, tighten the terminal screws
to the specified torques, otherwise, overheating may occur and
possibly cause extensive damage inside the heat pump.
