(34) Peak-cut timer (RC-EX3 only)
Power consumption can be reduced by restricting the maximum capacity.
Set the [Start time], the [End time] and the capacity limit % (Peak-cut %).
・
4-operation patterns per day can be set at maximum.
・
The setting time can be changed by 5-minutes interval.
・
The selectable range of capacity limit % (Peak-cut %) is from 0% to 40-80% (20% interval)
.
・
Holiday setting is available.
(33) Motion sensor control (RC-EX3 only)
The sensor determines the presence of people and the amount of activity, and the following controls are done by the motion
sensor. Following settings are necessary to activate motion sensor control.
(a) Infrared (motion) sensor setting : Installation setting of remote control.
The indoor unit which is set to "Enable" become valid.
(b) Infrared (motion) sensor control : Energy-saving setting of remote control.
The function which is set to "Enable" become valid.
(i) Power saving control
The set temperature is adjusted according to the presence of people and their amount of activity detected by the infrared
sensor.
(ii) Auto-off control
When no activity is deteced for 1 hour, unit will go stand-by mode. Unit will re-start operation automatically by activity
detection during the stand-by mode.

(26) Energy-saving operation (RC-EX3 only)
It operates with the setting temperature fixed at 28°C for cooling, 22°C for heating or 25°C for auto. When fan control in cooling/
heating thermo-OFF setting is “Set fan speed”, fan speed during thermo-OFF is changed to “Low”. (Maximum capacity is restricted
at 80%.)
(27) Warm-up control (RC-EX3 only)
Operation will be started 5 to 60 minutes before use according to the forecast made by the microcomputer which calculates
when the operation should be started in order to warm up the indoor temperature near the setting temperature at the setting time
of operation start.
(28) Home leave mode (RC-EX3 only)
When the unit is not used for a long period of time, the room temperature is maintained at a moderate leval, avoiding extremely
hot or cool temperature.
(a) Cooling or heating is operated according to the outdoor temperature (factory setting 35°C for cooling, 0°C for heating)
and the setting temperature. (factory setting 33°C for cooling, 10°C for heating)
(b) Setting temperature and indoor fan speed can be set by RC-EX3.
(29) Auto temperature setting (RC-EX3 only)
Setting temperature is adjusted automatically at the adequate temperature the center setting temperature is 24°C by correcting
the outdoor air temperature.
(30) Fan circulator operation (RC-EX3 only)
When the fan is used for circulation, the unit is operated as follows depending on the setting with the remote control.
(a) If the invalid is selected with the remote control, the fan is operated continuously during the fan operation. (mormal
fan mode)
(b) If the valid is selected with the remote control, the fan is operated or stopped when on the difference of the remote
control temperature sensor and the return air temperature sensor becomes bigger than 3°C.
(31) The operation judgment is executed every 5 minutes (RC-EX3 only)
Setting temperature Ts is changed according to outdoor temperature
This control is valid with cooling and heating mode. (Not auto mode)
(a) Operate 5 minutes forcedly.
(b) Setting temperature is adjusted every 10 minutes.
(i) Cooling mode.
Ts = outdoor temperature
−
offset value
(ii) Heating mode.
Ts = outdoor temperature
−
offset value
(c) If the return air temperature lower than 18°C in cooling or return air temperature becomes higher than 25°C in heating,
unit goes thermostat OFF.
(32) Auto fan speed control (RC-EX3 only)
In order to reach the room temperature to the set temperature as quickly as possible, the air flow rate is increased when the set
temperature of thermostat differs largely from the return air temperature. According to temperature difference between set
temperature and return air temperature, indoor fan tap are controlled automalically.
・
Auto 1: Changes the indoor fan tap within the range of Hi
↔
Me
↔
Lo.
・
Auto 2: Changes the indoor fan tap within the range of P-Hi
↔
Hi
↔
Me
↔
Lo.
(33) Indoor unit overload alarm (RC-EX3 only)
If the following condition is
at 30 minutes after starting operation, RC-EX3 shows maintenance code "M07" and the
signal is transmitted to the external output (CnT-2-5).
・
Cooling, Dry, Auto(Cooling) : Indoor air temperature = Set room temperature by remote c Alarm temperature difference
・
Heating, Auto(Heating)
: Indoor air temperature = Set room temperature by remote control - Alarm temperature difference
Alarm temperature difference is selectable between 5 to 10
°C
.
If the following condition is satisfied or unit is stopped, the signal is disappeared.
・
Cooling, Dry, Auto(Cooling) : Indoor air temperature = Set room tempe Alarm temperature difference -2
°C
・
Heating, Auto(Heating)
: Indoor air temperature = Set room temperature - Alarm temperature diff2
