When power supply is reset (1) Distinction of outdoor units When the power supply is reset, the outdoors are distinguished, and control is exchanged according to the distinguished result. (2) Setting of the indoor fan speed Based on EEPROM data, rspeed of the indoor fan is selected. Air volume control (1) Operation with [HIGH (H)], [MED (M)], [LOW (L)], or [AUTO] mode is performed by the command from the remote control. (2) When [FAN] button is set to AUTO, the indoor fan motor operates as shown in Fig. <COOL> (Room temp. ) - (Preset temp. ) °C +3 M+ +2. 5 *1 +2 +1. 5 +1 +0. 5 0 -0. 5 *1 *1 8-2. Filter sign display (1) The operation time of the indoor fan is calculated, the filter lamp (Orange) on the display part of the main unit goes on when the specified time (240H) has passed. When a wired remote controller is connected, the filter reset signal is sent to the remote controller, and also it is displayed on LCD of the wired remote control. (2) When the filter reset signal has been received from the wired remote control after [FILTER] lamp has gone on or when the filter check button (Temporary button) is pushed, time of the calculation timer is cleared. In this case, the measurement time is reset if the specified time has passed, and display on LCD and the display on the main unit disappear. 8-5-1 In heating operation, the freeze-preventive control works if 4-way valve is not exchanged and the condition is satisfied. High-temp release control The heating operation is performed as follows based on the detected temperature of Tc sensor. · When [M] zone is detected, the commanded frequency is decreased from the real operation frequency. After then the commanded frequency changes every 30 seconds while operation is performed in [M] zone. When [L] zone is detected, the commanded frequency is returned to the original value by approx. 6Hz every 60 seconds.
