1. ADJUSTMENT LOGICS
The thermostat's operating logic must be selected
in relation to the type of fan coil with which it is
installed; the selection criterion is:
• fan coil with on-off motor (Dip 8 in OFF
position)
• fan coil with brushless motor (Dip 8 in ON
position)
THERMOSTAT WITH THREE LEVELS
The figure below indicates fan operation in
Automatic mode (selector in AUTO position)
in relation to the proportional error; in manual
mode, the fan uses On-Off cycles on the selected
speed; in Auto mode, it performs On-Off cycles in
relation to V1 speed thresholds. If the fan coil is
equipped with an electric resistor, every time it is
activated it will require a pre-ventilation stage of
about 20" at speed V1. Once the ventilation with
heater ON request is met, a post-ventilation stage
takes place for 60" with speed V1. The Ventilation
Enable section outlines the fan enable-disenable
logic in relation to the water temperature in the
heat exchanger, while the Electric Resistor section
illustrates how ventilation with heater active takes
place.

VENTILATION LOGIC
Thermostat-controlled ventilation
The choice of adjustment by means of thermostat-
controlled ventilation (dip 3 OFF) requires the
ventilation to be switched off when the desired
setpoint is reached.
Continuous ventilation
The selection of continuous ventilation is made
with dip 3, which must be set as ON. In practice,
continuous ventilation provides ventilation even
when the thermostat has met the chosen speed
This function is disabled when the machine
does not have a shut-off valve (dip1 OFF).
In these particular cases, the fan will always be
managed with thermostat logic. The following
table shows the fan speed activated according to
the position of the selector:

The thermostat is off. It may however
start again in Heat mode if the room
OFF temperature falls below 7°C and the
water temperature is suitable (Anti-freeze
function).
When the chosen setpoint is reached, the
ventilation proceeds with the continuous

requests.
