DIP SWITCH CONFIGURATION
Turn off the power to the unit.
To be done in the installation phase, only by expert personnel.
By turning on or off Dip-Switches (fig. 2) inside the thermo-
stat, we get the following functions:
SW 1
Dip 1 (Default OFF )
Electric heater control:
- integration operation, OFF
- substitution operation, ON
Dip 2 (Default OFF )
Presence of the electric heater:
- absent, OFF,
- present, ON
Dip 3 (Default OFF)
System type:
- 2 pipes, OFF
- 4 pipes, OFF
Dip 4 (Default OFF)
Factory settings.
Dip 5 (Default OFF)
Position of the water sensor:
- water sensor on the battery, OFF
- water sensor before the valve, ON
Dip 6 (Default OFF)
Ventilation control:
- continuous ventilation, OFF
- thermostat ventilation heating mode, ON.
Dip 7 (Default ON)
Factory settings, ON
Dip 8 (Default ON )
Factory settings, ON

EXTERNAL FRESH AIR
The side openings on the polystyrene basin, permit the sepa-
rate attachment of an external intake fresh air pipe and a deli-
very pipe for treated air towards an adjacent room.
The external fresh air intake vent is covered by an easy to
remove cap made of plastic.
In the double version it is necessary to remove the semi-mar-
ked steel piece for the opening to be used.
To connect the vent with the canal, use the KFA flange (acces-
sory) fixing it to the basin with the four screws supplied.
Use material that is suitable for the operation with conti-
nuous temperatures of 80 °C. The ducts can be flexible made
of polyester (with spiral steel core) or made of corrugated
aluminium, externally coated with anti-condensate material
(fibre glass 12 ÷ 25 mm in thickness). When the installation
is complete, the non-insulated surfaces must be coated with
anti-condensate insulation (e.g. expanded neoprene, 6 mm
thickness).
To beat the fall in pressure due to the renewed air intake vent,
duct, filter etc., it is necessary to install a suitably-scaled fan.
For winter operation with the intake of outside air, it is advi-
sable to fit an antifreeze thermostat set at 2 °C, with the bulb
placed on the water outlet pipe, that shuts off the supplemen-
tary fan.
The external air flow must not exceed 10 % of the total air
flow to prevent operating problems or excessive noise.
Install outside an intake grill with filter frame that can be
inspected, to prevent dust and leaves being sucked in that
could block up the unit's heat exchange battery irreparably.
The installation of the filter also avoids the installation of a
channel closure gate during periods of inactivity.
DELIVERY OF TREATED AIR TO ADJACENT ROOM
The delivery of the air towards the adjacent room requires
the closure of the delivery channel in the basin, correspon-
ding with the duct, with isolating tape (supplied with the KFA
accessory flange).
In the double version it is necessary to remove the semi-mar-
ked steel piece for the outlet to be used.
The aperture of the delivery is closed. To open it apply the
flange (accessory KFA) fixing it to the sink with 4 screws sup-
plied, cut the polystyrene following the indented track and
the edge of the flange being careful not to damage the parts
behind.
Close the delivery grille that corresponds to the side occupied
by the same flange with the gasket supplied with the KFA
accessory.
It is necessary to install an air recovery vent on the wall divi-
ding the two air-conditioned room the unit is installed in and
the adjacent room.
Make the channel as described in the "External and fresh air"
chapter.
