1. Sensor Diagnose:
2 seconds after the sensors open circuit or short circuit, the unit will turn off automatically and the LED will show
E0 until the sensors resume.
Firstly check whether Terminal CN2 on
the indoor mainboard contact well or
not?
Pull out the terminals on the indoor
mainboard and reinsert them.
Replace with new sensor.
Pull the sensor out of the mainboard
1) Measure the value of resistance
between its two jumpers
2) Measure the temperature at the
room temperature sensing head.
Check the specifications of the sensor
to deside whether the sensor is
damaged or not?
The Indoor PCB is broken. Replace with new indoor PCB

2. Keystroke circuit error diagnose:
When power on for the first time, the PCB will check the keystroke circuit, is the sampling value is defferent
with the theory value, the LED will show E1, which means failed keystroke circuit. The keyboard is locked and
so invalid, but the remote control is working normally.
Check whether the keystroke can’t
get up with prssure. PCB is broken, replace a new PCB.
Repair the keystrokes on electrical
box to keep them away from the
keystrokes on PCB.
