Maximum Cooling Setpoint
Once set at a particular range, this will not
allow the set point to go above this range and
below R4 setting.
Example: Setting this parameter at 25
0
Cwill
not allow the set point to go above 25
0
C.
Also if the temperature reaches 25
0
C the
display will show Ht (High Temp)
indicating that the temperature has gone
above the range in this parameter and at this
point the alarm will come on.

Minimum Cooling Setpoint
Use UP/DOWN keys to get desired range &
press set key to confirm.
Once set at a particular range, this will not
allow the set point to go below this range and
above R3 setting
Example: Setting this parameter at -30
0
C
will not allow the set point to go below
-30

the display will show Lt (Low Temp)
indicating that the temperature has gone

Time delay for compressor1 restart
E.g. If this parameter is set at 3MIN,then
after cutting off the compresso1r at set
temperature compressor1 will not
