2-2 Feature of program timer
(1) Daily timer function
Daily timer can be set in 0 minutes units for up to 2 hours.
Each unit can be set for unit ON, unit OFF, or setback operation.
(2) Setback operation (PAC-SC2PTA)
Set back operation is useful for reducing running costs
e.g. At a hotel with a 2-hour system
8:00~2:00 Cooling operation with set temperature at 26°C
2:00~8:00 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.
1. REFRIGERANT PIPES
Service Ref. : PKH-1.6GKL / PKH-2GKL
: PKH-1.6GKLH / PKH-2GKLH
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 minutes, no air will enter, and there will be no need for air purging. Remove the blind
caps and make the connections within minutes. After the connections 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 0m, 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).
2. TIMER
When using a program timer, PAC-SC2PTA, a program timer adapter (PAC-82AD) is also needed.
