!
Daily timer function
Daily timer can be set in 30 minutes units for up to 24 hours.
Each unit can be set for unit ON, unit OFF, or setback operation.
@
Setback operation
Set back operation is useful for reducing running costs.
e.g. At a hotel with a 24-hour system
8:00~23:00 Cooling operation with set temperature at 26˚C
23:00~8:00 Setback operation with 2 degrees of setback
As shown in the chart on the right, the set temperature rises 2
degrees automatically during the setback operation. When the
setback operation ends, normal operation will begin.
#
Weekly timer function
Daily timer function can apply to each day of the week.
Note 1. How to connect refrigerant pipes.
Factory supplied optional refrigerant pipings contain refrigerant at the above atmospheric pressures. As long
as the connection takes no more than 5 minutes, no air will enter, and there will be no need for air purging.
Remove the blind caps and make the connections within 5 minutes. After the connecitons for the indoor and
outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow.
If piping length exceeds 5m, an additional charge of refrigerant is needed.
Note 2. The following main parts are contained in the optional refrigerant piping kit.
Heat insulating cover, vinyl tapes, nipples, sleeve and flange (for wall hole), connecting cables.
