1. Compressor Control
(4) Special control of compressor.
¶ Operation of the P/C compressor
When current capacity is not 0, the compressor does not stop.
¶ AC compressor start delay (for outdoor units)
When two compressors are to be started, the AC compressor is started 15 seconds after the P/C compressor.
(22.4 kw, 28 kw outdoor units)
¶ For compressors, when a compressor is stopped, it is not restarted for 3 minutes. During this period, the current
capacity does not increase. However, stops before and after reverse-cycle starting and reverse-cycle defrosting
are excluded from this rule.
¶ When the AC compressor starts while the P/C compressor is working, current capacity is set as minimum capacity
for 30 seconds and the AC compressor is started. (22.4 kw and 28 kw outdoor units)
¶ The above mentioned control takes precedence over all other control.
¶ Speed on current capacity increase
The microcomputer selects the optimum value for the speed at which the current capacity increases according to
the operating conditions. In the fastest case, the current capacity immediately increases to the maximum; in the
slowest case, the current capacity increases at 1 step / 60 seconds.
