Fan Revolution

Fan Revolution: You may preset the revolution of the internal agitation fan in the
range from 1 (low speed) to 10 (high speed). See the operating instructions of your
system for the fan revolution (rpm), which varies with systems.
If your system cannot control the fan revolution, the programmable controller
automatically skips this function. If your system is equipped with optional automatic
damper controller, you may preset the damper aperture at 5 different levels.

time, which creates the end segment. You may preset the fan controller at ON/OFF or

[Repeat Command]

[Repeat Command]
Repeat Command allows you to repeat a series of segments as many time as yon want.
This command is composed of 2 parameters; Repeat Start Segment and Repeat
Frequency.

Repeat Start Segment: Program repeats the section between the segment designated
as the repeat start segment and the segment immediately before the repeat start
segment.

Note

Note: (1) Repeat Command works for only the segments that were input and preset

before the command. In other words, you cannot repeat the segmen4 which
you preset after the repeat command.

(2) You cannot preset the nesting of a repeat command, which means to insert a

repeat command into the existing repeat command, as shown in Fig. 2.4.1. It
is also impossible, as shown in Fig. 2.4.2, to preset a repeat command across
the existing repeat command.
