1) Sleep timer
Set the duration of time from the present to the time to turn off the air-conditioner.
It can be selected from 10 steps in the range from “OFF 1 hour later” to “OFF 10 hours later”. After the sleep timer
setting, the remaining time is displayed with progress of time in the unit of hour.
2) OFF timer
Time to turn OFF the air-conditioner can be set in the unit of 10 minutes.
3) ON timer
Time to turn ON the air-conditioner can be set. Indoor temperature can be set simultaneously.
4) Weekly timer
Timer operation (ON timer, OFF timer) can be set up to 4 times a day for each weekday.

(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 controller display during the operation stop
1) 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 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 controller), the
fan operates with the set airflow volume regardless of the thermostat ON/OFF.
