• Cascade parameters. This menu is activated only if the
heat pumps are more than one (max. 4). The manager
deals with the activation and deactivation of the heat
pumps according to the parameters set and to a possible
request on the system.
As a result of a heating request the heat pumps are
activated in sequence, the activation of an individual
heat pump is determined according to the flow tem-
perature of the heat pumps in set configuration and
to the heating-set. If the flow temperature of the heat
pumps is lower than the heating-set value minus the
activation band divided by 2, then after a period equal
to the activation delay time, the next machine will be
started and so on up to the maximum value set in the
system definition parameter (P07).
Vice-versa if, after a deactivation delay time, the flow
temperature of the heat pumps is higher than the
heating-set value plus the activation band divided by
2, then one of the heat pumps will be switched off and
so on up to complete switch-off of the heat pumps.
In the event of a domestic hot water or puffer request
the operation is similar.
In the event of cooling requests the logic is inverted.
(Activation if the flow temperature of the heat pumps
is greater than the cooling-set plus activation band
divided by 2).
- Battery management.
- Simultaneous. All machines in set configuration will
intervene.
- Cascade. The machines are activated in sequence.
Attention: in case of installation in set configuration,
each heat pump must be equipped with omnipolar
disconnection.
