Setting for Long Piping
Outline
When the piping length exceeds 10 meters, the target discharge pipe temperature is calculated at a lower
level due to pressure loss in the piping system. The target discharge pipe temperature is corrected to a
higher level by cutting the jumper wire (S50) for long piping provided on the outdoor control PCB in order to
avoid lowering of performance due to insufficient pressure reduction.
Details of the
Control
Setting has been made for long piping (S50 jumper wire is cut).
Being controlled by motor-operated valve
Operating frequency is more than FLONG.
When the conditions of
and
and
are established, raise the target discharge pipe temperature
additionally by DLONG.

Constants
Refer “Control PCB” on page 14 for S50 Jumper.
