There are 4 different and alternative logics to select the
thermostat operating modes, according to the controller
configuration setting:
• Local: chosen by the user pressing the MODE key
• Distance: based on the status of digital input DI1
• depending on the water temperature
In case of a water probe alarm, the mode
control returns temporarily to Local mode.
• depending on the air temperature
Where:
• Set is the temperature set with the arrows
• NZ is the neutral zone
The operating mode of the thermostat is indicated on the
display by the symbols COOLING and HEATING.

Controller for units
VENTILATION
GENERAL ASPECTS
The control can manage two types of ventilation:
• step ventilation with a set number of selectable speeds
• modulating ventilation with variable speed between 0%
The use of one or the other type of control depends on the
type of ventilator (step or modulating) installed on-board
the machine. Step adjustment itself can follow two different
logics based on the type of valve/s (ON/OFF or modulating).
In brief, the automatic adjustment logics managed by the
controller (and described in detail here below) are as follows:
• step ventilation with 0N/OFF valve (or not installed) and 3
• step ventilation with 0N/OFF valve (or not installed) and 4
• step ventilation with modulating valve and 3 speeds, in
• step ventilation with modulating valve and 4 speeds, in
• modulating ventilation adjustment with ON/OFF valve, in
• modulating ventilation adjustment with modulating valve.
NATURAL CONVECTION
For units with valve, by enabling the parameter from the
configuration menu, ventilation for heating is delayed by
0.5°C to allow for an initial natural convection phase.
STEP VENTILATION
Use the UP/DOWN keys to choose from the following
speeds:
• Automatic SPD.:depending on set temperature and
• Extra-low spd: can only be selected if the unit is 4
• Low SPEED
• Medium SPD.
• High SPD.
