Heat Pumps (P31); Other Functions (P61 - P69) - Immergas System Manager Kit Instructions And Warnings

5.4.2 Heat pumps (P31)

The system allows you to choose the model of heat pump
used (max. 4).
Machine power is automatically detected by the system.
N.B.: hook the heat pump up to the power supply only
once all necessary settings have been made.
The following pages will be explored further in the
chapter relative to heat pumps.

5.4.3 Other functions (P61 - P69)

The screen shown here below allows you to enable the
presence of the solar circuit and the number of pumps
included in this circuit.
N.B.: If the solar circuit is enabled it is also possible to
enable the solar integration for central heating function
(puffer).
- Number of pumps. (1 pump, 2 pumps, solar disabled);
PUFFER management enables the heating of a technical
water storage tank for heating and domestic hot water.
- Presence (P62). Enable/disable solar heating integration
(Yes / No);
- Pre-heating (P62). Lets you enable Puffer pre-heating in
a permanent manner (Yes / No);
- Zone activation (P62):
- upon request: the zone pump activates upon receiving
a request;
- in temperature: the zone pump activates upon request
only if the puffer reaches the set zone setpoint.
- Hysteresis ON (P63). The generator turns on for a setpoint
lower than setpoint required + Hysteresis ON;
- Hysteresis OFF (P63). The generator turns on for a set-
point lower than setpoint required + Hysteresis OFF;
- Gen.offset (P63). Generator required setpoint correction
value.
- DHW OFF (P63): Upon receiving a DHW request, the
generator deactivates for a DHW temperature Exceeding:
DHW setpoint + DHW OFF.
N.B.: if photovoltaic is active, pre-heating is automatically
enabled with a fixed set equal to the maximum allowed
by the heat pump.
- Thermal discharge (P64). One can decrease the tem-
perature of the storage tank (usually a domestic hot
water storage tank) when the temperature read by the
probe on the storage tank exceeds the TΔ set (Delta
temp.) compared to the value detected on the cold
probe (pool or tank). The function is disabled when
the two temperatures are equivalent.
- Separate management of central heating and cooling
(P65). Allows to control a 3-way valve to choose wheth-
er to use the central heating system or the cooling one.
- Enable generator switch off (P65). It lets you switch
off all generators via an external control (Yes / No).
This function is useful if using a thermoflue.
Attention: if the generator switch-off signal is active,
the cooling stage is also deactivated.
- System decoupling (P66). It allows the system to be
controlled also through a plate exchanger downstream
of the heat pump.
- Photovoltaic (P66). It supports heat pump use when
photovoltaic panels are operating.
- System probe (P66). It allows managing the system
through an additional generator flow probe.
- Thermostat-controlled technical water storage tank
(P67 to P69). This function enables the management of
a technical water storage tank that is temperature-con-
trolled by means of a probe. The inertial storage tank
can work as heating and cooling.
- Presence (P67). Activated/deactivates the thermostat
controlled thermal storage tank (Ne/Ano).
- Maintaining active (P67). It makes it possible to
maintain the inertial storage tank in temperature
permanently (Ne/Ano).
- Zone activation (P67):
- upon request: the zone pump activates upon receiving
a request;
- in temperature: the zone pump activates upon request
only if the storage tank reaches the set zone setpoint.
