2. Writing the correction value of the room temperature on the wiring diagram
After setting the correction value of the room temperature (the inlet air temperature), follow 11. DISASSEMBLY
INSTRUCTIONS to disassemble the indoor unit, and then write the correction value (any of 3, 4, or 5) on the wiring dia-
gram with a ballpoint pen, etc.
(e.g. The numerical value is described in the bold square.) (Figure 3)
If the indoor electronic control P.C. board is replaced in servicing, the correction value is reset. The numerical value (any
of 3, 4, or 5) described on the wiring diagram will be needed when a service man sets the correction value again after
replacing the P.C. board.
NOTE 3: The instruction for setting the correction value again is attached to the indoor electronic control P.C. board of
the service part as well.
If you cut the jumper wire JR24 (Refer to 10-7.), a correction value of the room temperature during heating operation turns
to 0°C regardless of the correction commands from the remote controller. (Figure 4)
