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

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.

8.13 Condensation discharge

The condensation discharge network must be suitably sized and the pipeline positioned so that it keeps a constant inclination, never less than 1%.
In the vertical installation, the discharge pipe (16 mm diameter) is connected directly to the discharge tray, positioned at the bottom of the side shoulder underneath the hydraulic fixtures.
- If possible, make the condensation liquid flow directly in a gutter or a “rainwaters” discharge.
- When discharging directly into the main drains, it is advisable to make a siphon to prevent bad smells returning up the pipe towards the room. The curve of the siphon must be lower than the condensation collection bowl.
- If the condensation needs to be discharged into a container, it must be open to the atmosphere and the tube must not be immerged in water to avoid problems of adhesiveness and counter-pressure that would interfere with the normal outflow.
- If there is a height difference that could interfere with the outflow of the condensation, a pump must be mounted:
- In a vertical installation mount the pump under the lateral drainage tray;
A B
Discharge fitting Pipe for the flow of liquid
Such pumps are commonly found in commerce. However, on completion of the installation it is advisable
to check the correct outflow of the condensation liquid by slowly pouring about ½ l of water into the collection tray in about 5-10 minutes.
Mounting the condensation discharge pipe in the vertical version
Connect to the condensation collection tray discharge union a pipe for the outflow of the liquid blocking it adequately. Check that the drip-collector extension is present and correctly installed.
Make sure that the machine is installed perfectly level or with a slight inclination towards the condensation discharge;
Insulate carefully the inflow and outflow pipes up to the machine union to prevent any drops of condensation outside the same collection bowl;
Insulate the bowl condensation discharge pipe along all of its length.

Should one of the following anomalies occur, contact Technical Service Assitant or an authorised qualified person, but do not intervene personally.

12.1 Table of anomalies and remedies

Out of warranty repairs and maintenance can be performed by Technical Service Assitant or by qualified personnel.
EFFECT CAUSE REMEDY
A delayed activation of the ventilation respect to the new temperature or function settings. The appliance does not activate the ventilation.
The ventilation does not activate even if there is hot or cold water in the hydraulic circuit.
The appliance leaks water during the heating function.
There are formations of dew on the front panel.
There are drops of water on the air outlet grill.
The appliance leaks water only during the cooling function.
The appliance makes a strange noise.
The circuit valve needs some time to open and as a result the hot or cold water takes time to circulate in the appliance.
No hot or cold water in the system.
The hydraulic valve remains closed
The fan motor is blocked or burnt out.
The micro-switch that stops the ventilation when the filter grill is opened does not close correctly. The electrical connections are not correct. Leaks in the hydraulic connections of the system. Leaks in the valve unit. Check the state of the gaskets.
Thermal insulation unstuck.
In situations of high humidity (>60%) condensation could form, especially at the minimum ventilation speeds.
The condensation bowl is blocked. Slowly pour a bottle of water in the low part of the
The condensation discharge does not need an inclination for correct drainage.
The connection pipes and the valve unit are not insulated well.
The fan touches the structure.
The fan is unbalanced.
Check the clogging of filters and clean them if necessary.
- The ventilation does not activate even if there is hot or cold water in the hydraulic circuit.
- The appliance leaks water during the heating function.
- The appliance leaks water only during the cooling function.
- The appliance makes an excessive noise.
- There are formations of dew on the front panel.
Wait for 2 or 3 minutes to open the circuit valve.
Check that the water boiler or cooler are functioning correctly. Dismount the valve body and check if the water circulation is restored. Check the working efficiency of the valve by powering it separately with 230V. If it activates the problem could be the electronic control. Check the windings of the motor and thefree rotation of the fan.
Check that by closing the grill the micro-switch contact is activated.
Check the electrical connections.
Check the leak and fully tighten the connections.
Check the correct positioning of the thermoacoustic insulation paying attention to that in the front above the finned battery. As soon as the humidity starts falling the phenomenon disappears. In any case the presence of a few drops of water in the appliance does not indicate a malfunction.
battery to check the drainage; if necessary, clean the bowl and/or increase the inclination of the drainage pipe.
Check the insulation of the pipes.
Check the clogging of filters and clean them if necessary. The unbalancing causes excessive vibrations of the machine; replace the fan.
Clean the filters.
