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 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 Grant Interface relay Box
The Grant EP002 heat pump interface box (supplied with the heat
pump) is designed to provide the volt free switching required by the
Aerona³, using the heating and hot water switched live outputs from
the heating system wiring centre.
This box can be installed next to the wiring centre. Alternatively, it
can be located nearer to the Aerona³ heat pump, but not installed
externally.
Refer to Section 6.10 for system control wiring diagrams including
the connection of the interface relay box.
6.9 Wiring Diagrams
Refer to Appendix B for wiring diagrams of the HPID12R32 unit in
the Aerona³ heat pump range
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.
