(2) Since the ON timer, sleep timer
and OFF timer are set in parallel, when the times to turn ON and OFF the airconditioner are duplicated, the setting
of the OFF timer has priority.
(e) Remote control display during the operation stop
When the operation is stopped (the power supply is turned ON), it displays preferentially the “Room temperature”, “Center/
Remote”, “Filter sign”, “Inspection” and “Timer operation”.
(f)
Hot start (Cold draft prevention at heating)
(i) Operating conditions
When either one of following conditions is met, the hot start control is performed.
1) From stop to heating operation
2) From cooling to heating operation
3) Form heating thermostat OFF to ON
4) After completing the defrost control (only on units with thermostat ON)
(ii)
Contents of operation
1)
Indoor fan motor control at hot start
a) Within 7 minutes after starting heating operation, the fan mode is determined depending on the condition of
thermostat (fan control with heating thermostat OFF).
i) Thermostat OFF
①
Operates according to the fan control setting at heating thermostat OFF.
②
Even if it changes from thermostat OFF to ON, the fan continues to operate with the fan control at thermostat
OFF till the heat exchanger thermistor (ThI-R1 or R2, whichever higher) detects 35°C or higher.
③
When the heat exchanger thermistor (ThI-R1 or R2, whichever higher) detects 35°C or higher, the fan
operates with the set airflow volume.
ii) Thermostat ON
①
When the heat exchanger thermistor (ThI-R1 or R2, whichever higher) detects 25°C or lower, the fan is
turned OFF and does not operate.
②
When the heat exchanger thermistor (ThI-R1 or R2, whichever higher) detects 25°C or higher, the fan
operates with the fan control at heating thermostat OFF.
③
When the heat exchanger thermistor (ThI-R1 or R2, whichever higher) detects 35°C or higher, the fan
operates with the set airflow volume.
iii) If the fan control at heating thermostat OFF is set at the “Set airflow volume” (from the remote control), the fan
operates with the set airflow volume regardless of the thermostat ON/OFF.
b)
Once the fan motor is changed from OFF to ON during the thermostat ON, the indoor fan motor is not turned
OFF even if the heat exchanger thermistor detects lower than 25°C.
Note (1) When the defrost control signal is received, it complies with the fan control during defrosting.
c) Once the hot start is completed, it will not restart even if the temperature on the heat exchanger thermistor drops.
2) During the hot start, the louver horizontal control signal is transmitted.
3) When the fan motor is turned OFF for 7 minutes continuously after defrosting, the fan motor is turned ON regardless
of the temperatures detected with the indoor heat exchanger thermistors (ThI-R1, R2).
