SiUS04-904 Main Functions
Function and Control 31
Since the set temperature is shifted by 3.6°F(2°C) higher for 40 minutes, the compressor
speed lowers to save energy. The thermostat goes off due to the shifting of temperature so the
thermostat-off action is prohibited for 40 minutes to prevent this phenomena.
After this 40 minutes, the prohibition of the thermostat-off is cancelled and it resumes conditions
to conduct thermostat-off, depending on the room temperature. In or after this 40 minutes, if the
sensor detects the motion detection signal, it allows the set temperature and the fan speed to
return to the original set point, maintaining normal operation.
Others The dry operation cannot command the setting temperature with a remote controller, but
internally the set temperature is shifted by 1.8°F (1°C).
1.9 HOME LEAVE Operation
Outline In order to respond to the customer's need for immediate heating and cooling of the room after
returning home or for house maintenance, a measure to switch the temperature and air volume
from that for normal time over to outing time by one touch is provided. (This function responds also
to the need for keeping up with weak cooling or heating.)
This operation allows you to set a specific temperature and air volume for when you are not
occupying the space.
Detail of the
Control
1. Start of Function
The function starts when the [HOME LEAVE] button is pressed in cooling mode or heating mode
(including stopping and powerful operation). If this button is pressed while the operation is stopped,
the function becomes effective when the operation is started. If this button is pressed in powerful
operation, the powerful operation is reset and this function becomes effective.
The [HOME LEAVE] button is ineffective in dry mode and fan mode.
2. Details of Function
A mark representing [HOME LEAVE] is indicated on the liquid crystal display of the remote
controller. The indoor unit is operated according to the set temperature and air volume for HOME
LEAVE which were pre-set in the memory of the remote controller.
The LED (Red) of indoor unit representing [HOME LEAVE] lights up. (It goes out when the
operation is stopped.)
3. End of Function
The function ends when the [HOME LEAVE] button is pressed again during [HOME LEAVE]
