R7
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 250Cwill
not allow the set point to go above 250C.
Also if the temperature reaches 250C the
displa 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.
F R6 50 50 oC 0.5
R8
Minimum Cooling Setpoint
Use UP/DOWN ke s to get desired range &
press set ke 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 -300C
will not allow the set point to go below
-300C. Also if the temperature reaches -300C
the displa will show Lt (Low Temp)
indicating that the temperature has gone
below the range in this parameter and at this
point the alarm will come on.

C1
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
Restart for a minimum of 3min.This time
dela is also active at power on of the s stem
.
F 0 20 3 Min 1
C2
Time delay for compressor2 restart
E.g. If this parameter is set at 3MIN,then
after cutting off the compressor2 at set
temperature compressor2 will not
Restart for a minimum of 3min.This time
dela is also active at power on of the s stem
.
F 0 20 3 Min 1
C3
Time delay for compressor3 restart
E.g. If this parameter is set at 3MIN,then
after cutting off the compressor3 at set
temperature compressor3 will not
Restart for a minimum of 3min.This time
dela is also active at power on of the s stem
.
F 0 20 3 Min 1
