Initial Pull Down (IPD) provides faster cooling when the cabinet is powered up with
warmer inside temperature. During IPD, defrost will be skipped until the cabinet air
temperature reaches the cut-out temperature or the IPD duration expires. IPD oper-
ates only during power-up and can be enabled/disabled using this parameter.

It indicates the temperature at which initial pull down will be initiated.
• At Power-up: If the cabinet air temp. > Pit for more than 5 minutes, this will trig-

1800
To prevent the compressor from frequent cut-outs, it ensures that the compressor
runs for at least the specied time. It overrides the cut-out temperature. (Tip: Setting
it too high could lead to unneccessary deep temperatures)
Min Stop time (Sec.)

0
1800
To prevent the compressor from frequent cut-ins, the parameter ensures that the
compressor remains o for at least the specied time under this parameter. It over-
rides the cut-in temperatures. (Tip: Setting it too high could lead to unneccessary
warm temperatures)
