8.1 External heat-exchanger temperature too high (HTE):
The alarm occurs when the internal heat-exchanger temperature grows more than 70°C. The HTI alarm is cancelled
when the internal heat-exchanger temperature reduces below than 60°C. Possible causes are:
- Presence of obstructions near the inlet and outlet pipes;
- Obstructions inside the machine;
- Excessive dirt accumulated on the outdoor heat-exchanger;
- Malfunction ODU fan
- High external air temperature
8.2 Condensate max level alarm (OF):
In case of condensate max level switch opens continuously for at least 1minute, the air-conditioner stops working
(all the outputs are switched off, air-sweep and air-inlet closes). The state of alarm appears on the display. The
alarm is disabled in fan mode or standby mode. The causes that may have caused the alarm activation are:
- Lock or break the condensate pump;
- Malfunction of the float activate pump;
- Burning of the power transformer pump;
8.3 Internal heat exchanger temperature too low (LT):
The LT alarm occurs when the compressor is running, and the internal heat exchanger temperature is below -2°C
for more than 5 minutes, continuously. The alarm is cancelled when the internal heat-exchanger temperature
grows beyond 7°C. The causes that may have caused the alarm activation are:
- Presence of obstructions near the inlet and outlet pipes;
- Obstructions inside the machine;
- Excessive dirt accumulated on the indoor heat exchanger;
- Malfunction IDU fan
- Low external air temperature
8.4 Internal heat exchanger temperature too high (HTI):
The HTI alarm occurs when the internal heat-exchanger temperature grows more than 65°C and it is cancelled
when the internal heat-exchanger temperature reduces below than 42°C. The causes may be:
- internal air filter clogged.
- Internal heat-exchanger dirty
- Indoor air fan blocked or slowed.
- Suction screen clogged.
- Outside air temperature is too high. The air conditioner can’t operate in heating with temperatures above 25°C.
- Indoor air temperature too high due to excessive layers in the room where the machine is installed.
8.5 Discharge temperature too high
The maximum threshold beyond which the alarm is activated is 110 ° C but there isn’t a lower limit temperature
threshold for the automatic disabling of the alarm.
9. MANAGEMENT AND CONDENSATE DRAIN
The drain pump is activated only when the compressor is ON and micro-switch (pump running) closed. A second
switch operated by another float (high water), it shall stop the machine if it remains open for more than 60
seconds. If the contacts remain closed for more than a minute in fact, the shutter is powered (230 V) and discharge
water to a maximum interval of 3 minutes or until the switches are not open.
The shutter is normally scheduled to be closed in the state of standstill. In the heating mode (pump OFF) card
provides voltage electronic shutter to allow the discharge of water from the external heat-exchanger.
