- Number of pumps. (1 pump, 2 pumps, solar disabled).
It is possible to select the options for the solar heating in-
tegration function (Puffer) with the screen shown below.

- Presence. Enable/disable solar heating integration (Yes
/ No).
- Pre-heat active. Lets you enable Puffer pre-heating in a
permanent manner (Yes / No).
- Hysteresis ON. The generator turns on for a setpoint lower
than setpoint required + Hysteresis ON.
- Hysteresis OFF. The generator turns on for a setpoint
lower than setpoint required + Hysteresis OFF.
- Gen.offset. Generator required setpoint correction value.
N.B.: if photovoltaic is active, pre-heating is automatically
enabled with a fixed set equal to 55°C.
- Thermal discharge. One can decrease the temperature
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 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.
Allows to control a 3-way valve to choose whether to
use the central heating system or the cooling one.
- Enable generator switch off. It lets you switch off
all generators via an external control (Yes / No). This
function is useful if using a thermoflue.

- System Decoupling. It allows the system to be con-
trolled also through a plate exchanger downstream of
the heat pump.
- Photovoltaic. It supports heat pump use when photo-
voltaic panels are operating.
- System probe. It allows managing the system through
an additional generator flow probe-

In the case of hydraulic disconnections. The generator
required setpoint can be corrected up to a maximum that
can be set by the menu.
The correction is made until the temperature of the
common flow probe is reached. Once the activation
time has passed since the beginning of a requirement,
the correction is activated and incremented by 1°C for
every increasing time.
