SA5 Deactivation contact for excess power con-
sumption
The heat pump accepts an external deactivation signal from
contact SA5 if a power consumption management system is
used to disconnect devices based on set priority, thus avoid-
ing activation of the contactor on the power meter.
Configure the contact, selecting the desired function by set-
ting parameter 015D:
Contact closed: heat pump operation not allowed.
Contact open: heat pump operation allowed.

SA5 Reduced electricity rate contact
Forced refilling of the reserve storage tanks can be activat-
ed based on different electricity rates during the day.
During reduced rate periods, the heat pump can be forced
on so as to heat the domestic hot water or system storage
tank, where fitted.
Configure the contact, selecting the desired function by set-
ting parameter 015D:

Contact closed: forced operation during the reduced rate
period.
Contact open: heat pump operation at full electricity rate.
During operation at reduced electricity rate, contact closed,
the domestic hot water set point is 50°C, as shown in the
example, with the contact open it’s 47°C.
This allows operation at a higher temperature, within the
unit’s operating limits, exploiting the lower electricity cost.
