Sanyo KHS3682 + CH3682, CH3082 Maximum Current Value Change Function, Description of function

< CH3082 >

Maximum Current Value Change Function

The maximum current value is changed to 14A (for CH3082) or 17A (for CH3682) to prevent power breaker tripping. (It is set to 24A (in cooling) or 22A (in heating) when the unit is delivered from the factory.)

NOTE 1. When the high load is given (Outside temperature is high in the cooling operation, or outdoor temperature is low in the heating operation), the capacity is reduced.

When the maximum current value change function is to be enabled, make sure to receive the approval of the client.

2.The maximum capacity for cooling or heating operation is about as much as the rated capacity.

•Operates at the target frequency at Point A and below.

•Stops increases to the frequency between Points A and B.

•Reduces the frequency by 1 Hz per 0.5 seconds when Point B is exceeded.

•Stops operation, and restarts it appoximately 5 minutes later, if Point C is exceeded.

(May operate when sudden voltage fluctuations occur. Indicates trouble.)

<Maximum Current Value Change Procedure>

(1)Remove the inspection panel.

Refer to Fig. 2 in " Noise Reducing Control" for details.

(2)When the switch No.2 of the dip switch (SW01) on the control P.C.Board is turned ON, the maximum current value change. (Fig. 4)
