CONFIGURATION LIMITS
Unit configuration must take the following requirements into
account:
if there is a heater you will also need a water probe to
be installed:
if there is a heater and a valve, then the valve must be a
3-WAY (NO 2-WAY VALVES);
if Summer/Winter switching is set on "Auto on water
temp." then there must also be a water probe;
no heater must be installed on 4-pipe units;
with 4-pipe units with a single water probe, summer/
winter switching cannot be set on "Auto on water
temp.";
it is only possible to set summer/winter switching on
"Auto on air temp." if there is an electric heater or if the
unit has 4-pipes;
If SUMMER/WINTER switching is set on "Auto on water
temp." it is not possible to use a 2-way valve. The water
probe must be installed on a point in the hydraulic
circuit with minimum circulation.

USER MANUAL
IT IS strictly forbidden to reproduce this manual, even partially
CONFIGURABLE DIGITAL OUTPUT
The board has a digital output (identified by O7 on the electrical
diagram) and its status is linked to one of the operating statuses
of the unit reported in the list below:
Operating mode
Cooling or heating request
Cooling request
Heating request
ON/OFF status of the unit
Alarm installed
Dehumidify call
Humidify call
High room temperature
Low room temperature
No water consent to heating
No water consent to cooling
From supervisor
and selectable from the "DOUT Configuration" configuration
parameter. It is also possible to choose, using the next "Digital
output logic" parameter setting, whether the status of the relay
needs to follow the logic NO (Normally Open) or NC (Normally
Closed).
STAND-BY MODE
If no operation is performed on the user unit keyboard for 30
seconds the main screen goes into stand-by mode, which
can differ based on the settings of the "Stand-by Mode"
parameter, accordingly:
Stand-by mode = Off: the display goes completely
black;
Stand-by mode = Clock: the display goes partly black
and the current time and date are shown;
Stand-by Mode = Temperature: the display goes partly
black and the room temperature and any humidity are
shown, if the probe is installed.
SERIAL CONNECTION FAILURE
If the serial connection fails with the controller set as SLAVE,
EVO will either maintain the supervisor on/off settings and
summer/winter mode, or it will reset the last settings entered
from the keyboard, based on the relative configuration
parameter.
