Photovoltaic Integration; System Measurement Unit - Ariston SENSYS HD Manual

For each of the heat pumps present, it is possible to select the
parameters described below:
– "DHW aux heat source activation logic": the param-
eter allows to choose when to activate the secondary
heat source (heating elements, if enabled or present,
or an auxiliary heat source) of the heat pump in DHW
mode.
– In case of a heat pump malfunction and for heat
production integration ("Heat integr. and backup"):
the secondary heat source is activated both to inte-
grate domestic hot water at the heat pump and in
case of a heat pump malfunction.
– Only in case of a heat pump malfunction ("HP fail-
ure backup"): the secondary heat source is activated
only in case of a heat pump malfunction.
– "DHW operation mode": refer to the paragraph "Heat
Pump".

2.11.11 Photovoltaic integration

This menu is available for products that are configured for in-
tegration with a photovoltaic system (heating/cooling, hybrid,
DHW heat pumps) and that manage a DHW storage tank with
a temperature sensor.
– "PV offset DHW setpoint temperature": if a heating
heat pump or a hybrid system is installed, the param-
eter sets the degrees to be added to the temperature
set-point for DHW storage tank charge when additional
electrical energy is available from the photovoltaic sys-
tem.
– "PV setpoint temperature": if a DHW heat pump is
installed, the parameter sets the temperature set-point
for DHW storage tank charge when additional electrical
energy is available from the photovoltaic system.

In case of heat pump cascades, the parameter "PV offset DHW
setpoint temperature" for individual heat pumps that manage
a DHW storage tank with a temperature sensor can be set with-
in the relative sections.
