CENTRAL HEATING (P68)
- Hysteresis ON (P68). The generator turns on for a
setpoint lower than setpoint required + Hysteresis ON.
- Hysteresis OFF (P68). The generator turns on for a
setpoint lower than setpoint required + Hysteresis OFF.
- Gen.offset (P68). Generator required setpoint cor-
rection value. Generator setpoint = request setpoint +
gener. Offset.
COOLING (P69)
- Hysteresis ON (P69). The generator turns on for a
setpoint higher than setpoint required + Hysteresis ON.
- Hysteresis OFF (P69). The generator turns on for a
setpoint higher than setpoint required + Hysteresis
OFF.
- Gen.offset (P69). Generator required setpoint cor-
rection value. Generator setpoint = request setpoint
- gener. offset
N.B.: if photovoltaic is active and WINTER season, the
storage tank is automatically heated at a fixed set equal
to the maximum allowed by the heat pump.
If photovoltaic is active and SUMMER WITH COOL-
ING season, the storage tank is automatically cooled
at a fixed set equal to the minimum allowed by the
heat pump.
5.4.4 Setpoint Correction (P81 ÷ P84)
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
(P51) has passed since the beginning of a requirement,
the correction is activated and incremented by 1°C for
every increasing time (P81).
- Max Heat.corr (P82). Max correction during central
heating mode.
- Cool.Max corr (P82). Max correction during cooling
mode.
In the case of systems with zones, 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 zone
flow probe is reached.
Once the activation time (P83) has passed since the
beginning of a requirement, the correction is activated
and incremented by 1°C for every increasing time (P8).
- Max. corr Heat (P84). Max correction during central
heating mode.
- Max corr. Cool (P84). Max correction during cooling
mode.
- Enable external temperature probe presence.
- Not present
- From heat pump
- From boiler
- From the system manager
N.B.: If external probe use is enabled it is possible to
construct the climatic curve (see example heating curve
Fig. 5-2) for heating and cooling each individual zone.

The flow temperature range of the zones are:
- Central heating: 20 ÷ 85
- Cooling: 4 ÷ 25
These values can be resized based on the type of gen-
erator present.
The work range in heating phase:
- Heat pump: 20 ÷ 60 (max)
- Electrical resistance: 20 ÷ 60 (max)
- Boiler: 20 ÷ 85
- Magis Combo: 20 ÷ 80
- Pdc absence: 20 ÷ 85
- Enable generator switch off = ON: 20 ÷ 85
The work range in cooling phase depend exclusively from
the heat pump installed.
In reality the heat pump range value can be further
reduced based on the type of heat pump (see Chapter
related to the heat pump). However, in case of mixed
zones, the following values remain fixed:
- minimum heating temperature = 20°C
- maximum cooling temperature = 25°C
