1. Outdoor Unit Maintenance Remote Controller
6-8
Concerning the 7-segment 4-digit display of remote controller timer time
The unit Nos. of connected units are indicated by four 7-segment digits (
) and a colon.
The meaning of the colon changes in the same way to indicate unit Nos. up to 80.
Sample displays of connected indoor unit Nos.
NOTE
The change of the colon display (between unit Nos. 1 – 20 to unit Nos. 21 – 40) occurs automatically every 10
seconds. (However the display does not change if there are no higher-number units connected.)
To change the display to the higher-number units before 10 seconds have passed, press the
(FLAP)
button.
An 8-digit display is used for display of the compressor total operating time (in 1-hour units).
When the fi rst 4 digits are displayed, the bottom dot of the colon is lit. (Figure (A))
When the last 4 digits are displayed, the colon dot is not lit. (Figure (B))
The display of the fi rst 4 digits and last 4 digits changes automatically every 10 seconds.
It can also be changed by pressing the
(FLAP) button.
NOTE
The remote controller check function does not function with the outdoor unit maintenance remote controller (when
it is connected to the outdoor unit).
