Haier air conditioner | Edition: 20070116 |
2.1.1 Standard of temperature sensor under indoor environment.
When the line is in short circuit or open circuit, the indicator light will be alarming and the indoor fan motor will be off. It will resume to the original state automatically after it returns normally, and operates as usual.
Short circuit:
Temperature: above 126 degrees,
Hex: Above F8H,
Value of Resistance: Below 0.65K, above 4.85V.
Normal temperature:
Temp: 25 degrees,
Hex: 40H,
Value of Resistance: 23K,
Voltage: 2.33V.
Power failure:
Temp: below
Hex: below 08H,
Value of Resistance: Below 620K,
Voltage: Below 0.15V.
Bparameter=4200 R (25degrees) =23K
2.1.2Value of Resistance of indoor temperature sensor is ignored, when the heat mode is ON and the indoor fan is OFF, as well as after warm start indoor fan operate for 30 seconds. (in order to avoid affection of heat exchanger)
2.2When frequency increase to holding frequency
In order to oil return fully during operating, the system will must keep some frequencies for a period of time.

After Forced operation OFF at the start status, system will begin to control the temperature area.
2.3 Preset temperature correction
The preset temperature is corrected according to the operating mode, air capacity and forced operation status.
Only in the heat mode to correct the air capacity, confine to the low and middle speed of the air capacity.
Corrected value table for preset temperature:
- 10 -
