P-H-1
Spheros A/C Controller Instruction
1. Display
It indicates the internal temperature and the regulated
temperature.
PS: the display will always show the vehicle internal
temperature even when the motor is off.
2. Key
- On/Off
1st touch – turns on the equipment
- the equipment operates in refrigeration at high velocity
PS: If the led light is blinking, it indicates the compressor still has not started operating. If the light is on,
it indicates the compressor has started operating.
2
nd
touch – the equipment starts operating in refrigeration at low velocity.
3
rd
touch – turns off the equipment.
PS: It is always recommended to turn off the equipment before turning off the vehicle motor.
PS: When the air conditioner is activated for the first time, the compressor will be activated at
approximately 10 seconds. After the air conditioner turning off and its subsequent turning on (without
turning off the vehicle motor) the compressor will be activated at about 30 seconds.
HA – When the command panel shows HA, the compressor and the ventilators of the condenser will be
off for 3 minutes, after that, they will restart working again.
3. Key:
- turn down
or up
the desired temperature.
When you press any of these keys, the (blinking) display will show the selected temperature. For
turning it down or turning it up, keep pressing one of the keys until you get the desired temperature
value (minimum 16 e maximum 32 ). After 5 seconds without pressing one of the keys, the
℃
℃
temperature will be recorded and the display will once again show the temperature inside the vehicle.
4. Failure code
When the display shows one of the indications related below, it is an indicator of failures in the system.
HA – Indicates low or high pressure in the system. It may be a condenser obstruction or lack of gas.
OP – Sensor of temperature is open. Select one temperature below 24 so that the equipment may
℃
operate in refrigeration and above 24 so that the equipment may operate in ventilation.
℃
SC – Sensor of temperature in short circuit. On such a case, the equipment will operate at an internal
refrigeration temperature of 24 .
℃
AL – Indicates the alternator is not charging current.
