Control ]
-20- Operation Mode <PURY>
(1) Indoor unit operation mode
The operation mode can be selected from the following 6 modes using the remote controller.
(2) Outdoor unit operation mode
Note: When units in cooing and heating coexist, the operation mode (cooling main mode or heating main mode) will be
determined, based on the refrigerant pressure in the R2 refrigerant circuit and speed variation data.
(3) Operation pattern for automatic cooling/heating mode
When the automatic cooling/heating mode is selected from remote controller functions, the indoor temperature will be de-
tected in pattern as shown in the figure below, and the operation mode (cooling or heating) will automatically be selected.
(4) Relationship between the operation mode and the load capacity (kW) (within a system)
-21- DEMAND Control <PUHY/PURY>
Cooling/heating operation can be prohibited (Thermo-OFF) by an external input to the indoor units.
Note: When DIP SW4-7 is set to ON, the 4-step DEMAND control is enabled. While this control is enabled, the NIGHT
MODE will be disabled.
Refer to 2 [2] 2.(5) for detailed information on DEMAND control.
