SAVE BATTERY FUNCTION (AC / FAN)
The save-battery function starts
when the power falls below a value of 21,5V.
In this case, the system (AC or VENT) shuts down, also deactivating the fan function and the message E1
appears on the display and the battery symbol lights up.
When the power returns, for at least 10 seconds, to the value of 25V, the system is automatically reactivated,
starting up the condenser fan, followed by the evaporator fan and compressor
ERRORS SHOWN ON THE DISPLAY (AC / FAN)
Description
Message Symbol
Battery voltage
(The battery-saver device has cut in. Voltage has fallen below the
value of 21.5 V)
E1
Fan over current cut-out
(The condenser or evaporator fan overloads the central control
unit above the limited allowed. Possible cause: short circuit or
blockage of fan rotation.)
E2
Compressor locked
(The rotor is locked or the pressure inside the cooling circuit is too
high.)
E3
Minimum compressor rotation speed
(If the cooling circuit is overloaded, the compressor cannot
maintain the minimum rotation speed.)
E4
High temperature on the central control unit
(If the cooling circuit is overloaded or the ambient temperature is
high, the central control unit signals this situation.)
E5
Communication error
(There is no communication between the display and the central
control unit.)
E6
Temperature probe
(If the probe short-circuits or is not connected, the system stops.)
E7
Tilt
(The system shut-down device installed to operate in the event of
tilting has cut in.)
E8
REMOTE CONTROL
The remote control regulates both the conditioning function and the fan function.
Using the remote control it is possible to:
- Switch the system on and off (ref.a – see fig.2)
- Regulate the temperature (ref.b – see fig.2)
- Regulate the fan speed (ref.c – see fig.2)
- Engage the MAX AC function (ref.f – see fig.2)
- Modify the TIMER function (ref.a – see fig.2)
