Applicable units ■ R(Y)P71-250B
■ RY35-45E(A)Z7V1
Purpose The purpose of the simulated operation function is to avoid the unit from stopping if the heat exchanger
thermistor or air thermistor is malfunctioning.
Method If the air thermistor (for all models listed) or the heat exchanger thermistor is malfunctioning (out of its
normal range), simulated operation is carried out while malfunction is displayed on the remote control.
If the air or heat exchanger thermistor becomes normal again, the simulated operation function is
interrupted and the normal operation restarts. The malfunctioning error disappears.
Used input The simulated operation function uses the following inputs:
