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:
Description
Enable contact as:
0 = Reduced electricity rate
1 = Stop operation due to excess
power consumption
2 = Boiler backup
Contact closed: heat pump operation disabled.
Contact open: heat pump operation enabled.
SA5 Reduced electricity rate contact
Forced refilling of the reserve storage tanks can be activated
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:
Description
Enable contact as:
0 = Reduced electricity rate
1 = Stop operation due to excess
power consumption
2 = Boiler backup
Enable set point as:
0 = Economy
1 = Comfort
Set the ECONOMY domestic hot
water economy set point
Set the COMFORT domestic hot

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