Regulation with temperature probe: this value indicates on which probe the system
bases its adjustment when producing water; The possible values are:
— OUTPUT (U2): the probe used for adjusting the production of water is the one at
the output of the plate heat exchanger;
— INPUT (U1): the probe used for adjusting the production of water is the one at
the input of the plate heat exchanger;
— COMMON OUTPUT PROBE (U3 uPC): the probe used for adjusting the produc-
tion of water is the one at the common output if there are two plate heat ex-
changers;
NB: if selecting input based adjustment, in order to set a correct work
setpoint, keep in mind the addition or the subtraction (based on if hot
or cold operation) of the water production dierential to or from the
work setpoint
Type of reg.: this value indicates which logic is used for managing the adjustment;
The possible values are:
— PROP+INT: applies proportional control + integral;
— PROP: applies only proportional control;
Integ. time (Ki): this value indicates the integral time to add to the proportional
control (if the regulation type proportional + integral was selected);
8.7 SETS THE LOGIC FOR THE SETPOINT AND
DIFFERENTIAL IN COOLING MODE
This mask is used to select the logic to apply to the working setpoint, and the value
to assign to the dierential for cooling operation:
8.0°C

Dierential:
COMPENS.TEMP.
Cooling regulation
The type of setpoint indicates which logic is used for managing the working set-
point; the possible states are:
— FIXED SETPOINT: the system uses the values set by the user in the windows of
the set menu as the work setpoint (main and secondary setpoints);
— CLIMATIC CURVE: the working setpoint is calculated automatically based on the
data entered in the climatic curve;
Dierential: this value indicates the dierential applied between the water input
and output; this value depends on the ow rate value at which the system operates;
8.8 SETS THE LOGIC FOR THE SETPOINT AND
DIFFERENTIAL IN HEATING MODE
This mask is used to select the logic to apply to the working setpoint, and the value
to assign to the dierential for heating operation:
8.0°C
Installer
Dierential:
COMPENS.TEMP.
Heating regulation
The type of setpoint indicates which logic is used for managing the working set-
point; the possible states are:
— FIXED SETPOINT: the system uses the values set by the user in the windows of
the set menu as the work setpoint (main and secondary setpoints);
— CLIMATIC CURVE: the working setpoint is calculated automatically based on the
data entered in the climatic curve;
Dierential: this value indicates the dierential applied between the water input
and output; this value depends on the ow rate value at which the system operates;
8.9 CLIMATIC CURVE CONFIGURATION IN COOLING MODE
This window is used to set the temperatures (minimum and maximum) and the
maximum dierential that will be applied to the working setpoint in cooling mode
based on the minimum outside air temperature;
