THERMOSTAT CONTROL 0÷100 %
The figure indicates how the fan works in Automatic mode (switch in AUTO position), according to the proportional error. In manual mode
(with the selector in position V1, V2 or V3) the fan functions in
On-Off cycles depending on the chosen speed. 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 VMINAUX. Once the ventilation with heater ON request is met, a post-ventilation stage takes
place for 60" with speed VMINAUX. .
The dead band indicated in the figure can be 2°C or 5°C depending on the setting made for dip7.
THERMOSTAT-CONTROLLED VENTILATION
With adjustment on the basis of thermostat-controlled ventilation (dip 3 OFF), the ventilation function switches off when the set value
is reached.
CONTINUOUS VENTILATION
Continuous ventilation is selected by setting dip 3 ON. In this mode, ventilation continues at the selected speed even after the
set temperature value has been reached. This function is disabled if the machine has no shut-off valve (dip 1 OFF); in this case,
ventilation is always managed via thermostat-control logic. The following table shows the ventilation speed activated according to the
position of the selector:
GRADUAL VENTILATION START-UP
The thermostat offers gradual fan start-up control when the fan coil is enabled, to guarantee better environmental and acoustic
comfort (refer to the figure below).
THE START-UP CONDITIONS MAY BE AS FOLLOWS:
• Electrical activation of the fan coil with the operating mode selector in any position other than OFF.
• Activation of the fan coil by rotating the operating mode selector from OFF to AUTO, V1, V2, V3 or AUX.
• Closure of the MS contact if used for external enabling (dip 4 OFF), and from the CE input.
