VENTILATION CONTROL

Thermostat-controlled ventilation: The
choice of the regulation according to
thermostatically controlled ventilation
(dip3 OFF) foresees the switching off
of the ventilation when the setpoint is
reached. (See the dip switch settings
table).
Position
The thermostat is off. It may however start again in Heating mode if the room temperature falls
OFF
below 7°C and the water temperature is suitable (anti-freeze function).
AUTO On reaching the setpoint, the ventilation proceedes with the minimum continuous speed.
In this position, the minimum ventilation speed V1 is always active regardless of thermostat
V1
requirements.
In this position, the average ventilation speed V2 is always active regardless of thermostat
V2
requirements.
In this position, the maximum ventilation speed V3 is always active regardless of thermostat
V3
requirements.
In this position, the minimum Aux ventilation speed is always
Aux
active.
MINIMUM CONTINUOUS SPEED PARAMETERS
The "minimum continuous speed" is
linked to the position of dip switch 8
(see paragraph on dip-switch settings) in
the table below.

VALVE OPERATION

If a shut-off valve is present (dip1 ON),
the position of the probe can be man-
aged both upstream and downstream of
the valve itself (in the standard position
on the heat exchanger). The main differ-
ence between the two is in managing the
ventilation in different ways. If the water
probe is upstream of the valve (dip2
ON) or is not present, a heat exchanger
pre-heating function occurs and enables
Continuous ventilation: The continuous
ventilation is selected by means of dip3
that must be set to On. In practice the
continuous ventilation provides ventila-
tion even with thermostat fulfilled at the
speed chosen. This function is disabled if
the machine has no shut-off valve (dip1
OFF). In these particular cases, the ven-

the fan 2'40" after the first opening of
the valve.
The valve in question (for the heat
exchanger pre-heating function) is Y1 if
this is a 2-pipe system (dip5 Off), where-
as if it is a 4-pipe system it is Y2 (dip5
On).
The inhibition time of the fan is then
automatically calculated and depends
on how long the valve remains closed; in
tilation will always be managed with
thermostatically controlled logic.
The following table shows the ventilation
speed activated depending on the posi-
tion of the selector:

this way it could vary from a minimum
of 0' 00" to a maximum of 2' 40". This
ventilation enabling delay in relation
to the opening of the valve is reset if
the electric resistor is enabled, this is to
ensure greater user safety.
Refer to the specific table for the specific
parameters of the dip switches.
