Part 2 Functions & Controls

5.11.2 Inverter Compressor (18,24,30kBtu/h Model)

1)There can be two situations

(a)Temperature sensor is failed (Error Code 41)

(b)Abnormal high temperature discharge temperature (error code for high discharge will be generated) Both cases unit will stop.

2)Compressor working

(a)If discharge pipe temperature < T1 No limitation on compressor frequency

(b)T2 discharge pipe temperature < T off, (Hysteresis control) Compressor frequency down by 5Hz and expansion valve up by 10 pulse in every 1 min.

(c)Discharge pipe temperature Toff, Compressor will be off

System will stop if this situation occurs 5 times in 1 hour and error code will be generated.
