2.3 Set-up of auxiliary dip-switch functions B and C
There are two dip switches on the controller circuit board
for configuring unit operation as per requirements.
- The night-time heating operation logic is modified by
using dip switch C:
- in the ON position, the fan is always off, and heats the
room using radiation and natural convection, as with
traditional radiators; in the off position it operates as a
normal fan.
- By positioning dip switch B to ON, when cooling, the
fan operates at the minimum speed even after having
2.4 CP presence contact input connection
On closing the contact connected to the CP input (ref. A)
the panel is placed in stand-by mode.
If the contact is open the unit is active, if the contact is
closed it is deactivated when a key is pressed the
symbol flashes.
reached the set point, to allow for more uniform
operation of the temperature probe and to avoid
layering in the air. With the cursor in the OFF position,
the functions are cycled (4 minutes ON, 10 minutes
OFF).
The input cannot be connected in parallel to that of other
electronic boards (use separate contacts).

3.5 Water probe kit management
If the board detects the water temperature detecting probe
on the device positioned in the relevant compartment of
the battery, it starts in normal conditions. If the probe is not
connected, its absence is indicated by the blue and red
LEDs flashing together, and operation stops.
To confirm operation without the probe, press and hold the
summer/winter button for 5 seconds (ref. A).
This condition is saved by the board for future start-ups.

In any case, as and when the probe is connected, the unit
returns to normal operation with temperature thresholds.
If the unit operates with the probe connected and the water
temperature is not suitable for active functioning (over 20°C
when cooling, under 30°C when heating) the fan will stop
and the anomaly will be indicated by the corresponding LED
flashing (cooling: blue C or heating: red D).

4.4 Connections with 3-speed thermostats
The CV input is the board ON/OFF which when open puts
the board in stand-by. It must be bridged to the L terminal
on the 230V power supply to activate solenoid valve Y1.
The 4 speed inputs V1, V2, V3 and V4, when bridged
to the L terminal on the 230V power supply, activate the
fan if the S1 input to which the grill safety microswitch is
connected is closed. The sequence is: maximum speed
(1400 rpm on terminal V1), medium speed (1100 rpm on
terminal V2), minimum speed (680 rpm on terminal V3)
and supersilent speed (400 rpm on terminal V4).
Connect the three thermostat speeds to 3 out of the 4
available inputs as per the characteristics and use of the
room: connect, for example, medium speed V2, minimum
V3 and supersilent V4 for residential applications, when
greater silence is required, whereas V1, V2 and V3 can be
connected for commercial applications where the thermal
yield is more important.
If multiple inputs are simultaneously closed, the motor will
run at a number of revs equal to that of the connection
with the highest speed.
Multiple cards can be connected in parallel to a single
thermostat, also using different speeds.

4.5 LED signals
The LED (ref. A) is off if the CV input is not closed (stand-by
condition).
It turns on when the CV contact is closed and indicates
normal operation.
• Flashes frequently if the grille microswitch S1 is activated
due to the filter cleaning operation
• 1 flash + pause indicates a fan stoppage alarm due to
unsuitable water (with H2 water probe connected).
• 2 flashes + pause due to a motor alarm (e.g. blockage
caused by foreign objects, faulty rotation sensor).
4.6 Water probe management with 3-speed thermostat
If the board is used with electromechanical thermostats, or with
other commercial controllers with water probe, the on-board
probe H2 should not be connected and the fan is controlled by
the remote control.
If on the other hand the controller is not set up for managing the
water probe, this function can be performed by the board, by
connecting the 10 kΩ probe on the battery to the H2 connector
on the board (ref. B).
In this case the board carries out the minimum temperature
function for heating operations and maximum temperature
function for cooling. Therefore, if the water temperature is not
suitable for active operation (above 20°C when cooling, under
30°C when heating) the fan is stopped and the anomaly is
signalled by a single flash + pause of the LED (ref. A).
• 3 flashes + pause indicates a disconnected or faulty
water probe alarm.
The discrimination between heating/cooling is actuated via the
Summer-Winter (ref. C) input of the board: leaving it open the
board activates heating, closed activates cooling.
If after having connected the probe it is disconnected or
measures incorrect values (e.g. installation of 2 kΩ probe in the
place of the 10 kΩ probe) the anomaly is signalled by 3 flashes
+ pause of the LED (ref. A) and operation is stopped.
To confirm operation without a probe, turn the power to the
board off and then on again.
This condition is saved by the board for future start-ups.
In any case, as and when the probe is connected, the unit
returns to normal operation with temperature thresholds.
