over 3 min over 5 min

over 30 sec

In Cool Mode, the operation of the Compressor (COMP), Outdoor Fan (OFAN) and Indoor Fan (IFAN)

are determined by the difference between the Room Temperature (RT) and the Set Point Temperature

(SPT) as in the graph above.

Notes:

1. In this graph, the IFAN is operating in the “Auto Fan Speed” setting. If the user has selected the low,

medium or high fan speed, the IFAN will run constantly at that speed only.

2. In addition to the value of (RT-SPT), the operations of the relays are also controlled by protection

delays. For example, (a) the minimum On/Off time of the COMP is 5 min and 3 min respectively, and

(b) the IFAN can change speed only after it has operated at the same speed for 30 sec.
