7.2. OPERATION OF FORCED CONVECTION
The fan connected to the network, that will work
according to the following guidelines:

Manual mode
The control module operates the fan in four
possible operating speeds, driven by the remote
control buttons which are configured as follows:
- A - Button: speed increases
- B - Button B: speed decreases
- C - Button: directly activates Pot. max
- D-Button: stops and auto mode
Fig.- 10. Remote control with 4 buttons.
The fan will turn off automatically if past 3
o'clock, the temperature sensed by the NTC does
not exceed a minimum value.


Automatic mode
When the array is connected to the 220 V. AC or
pressing the button-the-D remote control mode
remains the surveillance module with the fan
stopped.
When the temperature sensed by the probe NTC
temperature exceeds minimum recorded as
running in the control module the fan rotates at
high speed while remaining on this speed while
the temperature is higher than the minimum
recorded as stop.
Also put on the fan, at any temperature, when
the NTC probe is disconnected or faulty, as the
security mode.

STOP
IMPORTANT
Automatic mode is not a programmable system of
comfort, but a security system controlled by a NTC
probe. This security system is activated when the
NTC probe detects the temperature mentioned
before, so that it could avoid damages in the fan,
produced due to the possible exposure at high
temperatures.
