(14) Discharge pipe sensor disconnection protection control
(a) When the compressor speed is other than 0 rps.
(i) Tho-D(10) - Tho-D(0) < 8 °C, and Tho-D(10) - Tho-A(10) < 5 °C
The compressor speed is set on A rps for 5 minutes. After 5 minutes, the compressor speed is set on B rps for 5 minutes.
(ii) Tho-D(20) -Tho-D(15) < 5 °C
The compressor speed is set on 0 rps.
(b) Once the unit is stopped by this function, it is not restarted.
Notes (1) Tho-D(X): After compressor operation, the discharge pipe temperature sensor after X minutes.
(2) Tho-A(X): After compressor operation, the outdoor air temperature sensor after X minutes.
