doC - Door Sensor (Normally closed type)
doo - Door Sensor (Normally open type)
ESP - Eco Switch - Push button type
ESt - ECO Switch - Toggle type
dES - Defrost switch - Push Button type only
Desired configuration for relay 2
nC - Not Connected
dEF - Configured for defrost heater or defrost valve
Fan - Configured for evaporator fan
Description
Cut-out temperature at coldest position of the spindle (thermostat knob)
Cut-out temperature at warmest position of the spindle (thermostat knob)
The difference between the cut-out and the cut-in at coldest position of the ther-
mostat.
The difference between the cut-out and the cut-in at warmest position of the ther-
mostat.
Initial Pull down
OFF - Disable
ON - Enable
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.
Maximum time initial pull down can run. Initial pull down will terminate as soon as
this time expires regardless of the cabinet air temperature
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-
ger the Initial pull down.
Description
To prevent the compressor from frequent cut-outs, it ensures that the compressor
runs for at least the specified time. It overrides the cut-out temperature. (Tip: Setting
it too high could lead to unneccessary deep temperatures)
To prevent the compressor from frequent cut-ins, the parameter ensures that the
compressor remains off for at least the specified time under this parameter. It over-
rides the cut-in temperatures. (Tip: Setting it too high could lead to unneccessary
warm temperatures)
