4.2.3 Parallel shifting
Press the selector
. Turn the selector and set the most suita-
ble value. Press the selector
IMPORTANT:
If the room temperature is higher than the desired value,
the curve must be shifted lower. If the room temperature
is too low, the curve should be shifted upwards. If the
temperature of the room corresponds with the desired
value, the curve is correct.
In the graph below, the curves have been divided into
two groups:
– Low-temperature systems
– High temperature systems
The two groups are divided according to the different
point of origin of the curves, which for high-temperature
systems is higher than 10°C, a correction usually made to
the delivery temperature in these types of systems dur-
ing climatic adjustment.
4.2.4 Proportional room influence
Turn the selector and set the most suitable value, then press
the
selector to confirm. The influence of the room sensor
can be adjusted to a value between 20 (maximum influence)
and 0 (no influence). In this way, the contribution of the room
temperature to the delivery temperature calculation can be
adjusted.
4.2.5 Maximum delivery temperature
Turn the selector
then set the most suitable value and
press the selector
to confirm.
4.2.6 Minimum delivery temperature
Turn the selector
then set the most suitable value and
press the selector
to confirm.
4.2.7 Thermoregulation type
Turn the selector
then set the most suitable value and
press the selector
to confirm.
Turn the selector and select:
– Conventional
– Smart temperature control (in this mode, the water flow
set-point is calculated using the information provided
in parameter 4.8)
4.2.9 Heat request mode
Turn the selector and select:
– Standard
– RT Time Programs Exclusion (in this mode, the heat de-
mands generated by the room thermostat remain ac-
tive also during the night-time period in programmed
mode)
– Force the heat request (the activation of this function
generates a constantly active heat request)
Repeat the steps described previously to set the values for
zone 2 (where present), by selecting menu 5.
NOTE:
For correct operation of the temperature adjustment types: 2.
Room sensor only: 3. Outdoor sensor only: 4. Room sensor plus
outdoor sensor, parameter 1.0.6 should be set to value 1, or the
AUTO function must be activated.

COOLING
4.5.0 Z1 Cooling T Set
Press the selector
. Turn the selector and set the delivery set-
point temperature value, if temperature control is deactivated
or with fixed point.
4.5.1 Z1 Cooling T range
Press the OK button. Turn the selector and select the temper-
ature range:
– Fan coil units
– Under-floor system
4.5.2 Select type
Press the selector
, turn the selector and set the type of tem-
perature control installed:
– 0 - ON/OFF devices (fixed water flow set-point specified
in par. 4.5.0)
– 1 - Fixed delivery temperature (fixed water flow set-
point specified in par. 4.5.0)
– 2 - Room sensor only (water flow set-point on the basis
of the outdoor temperature)
4.5.3 Slope
Press the selector
. Turn the selector and set the curve on
the basis of the type of cooling system.
Press the selector
to confirm.
– Fan coil units (curve from 18 to 33)
– Under-floor system (curve from 0 to 30)
The checking process for the suitability of the curve requires a
long period of time during which several adjustments may be
necessary.
