THERMISTOR 1 - TOP ZONE
This shows the pure thermistor reading with no
offsets taken into account.
2.
THERMISTOR 2 - TOP EVAPORATOR
This shows the pure thermistor reading with no
offsets taken into account.
3.
THERMISTOR 3 - BOTTOM ZONE
This shows the pure thermistor reading with no
offsets taken into account.
4.
THERMISTOR 4 - BOTTOM EVAPORATOR
This shows the pure thermistor reading with no
offsets taken into account.
5.
THERMISTOR 1 - TOP ZONE OFFSET
(DO NOT MAKE AN ADJUSTMENT TO THIS WITHOUT
CONTACTING TECH LINE) This calibration is only to
be used if actual temperature at thermistor #1 is off
from set point. By adjusting the offset higher, we can
force the unit to drive the temperaturee down below
the set point. (example: adjusting from 0 to +2 will
drop the unit temperature 2 degrees)
6.
THERMISTOR 2 - TOP EVAPORATOR OFFSET
This shows the pure thermistor reading with no
offsets taken into account.
7.
THERMISTOR 3 - BOTTOM ZONE OFFSET
(DO NOT MAKE AN ADJUSTMENT TO THIS WITHOUT
CONTACTING TECH LINE)
8.
THERMISTOR 4 - BOT. EVAPORATOR OFFSET
This shows the pure thermistor reading with no
offsets taken into account.
9.
THERMISTOR 2 - SET POINT MINUS OFFSET
This shows the pure thermistor reading with offsets
taken into account.
10. THERMISTOR 3 - SET POINT MINUS OFFSET
This shows the pure thermistor reading with offsets
taken into account.
11. THERMISTOR 4 - SET POINT MINUS OFFSET
This shows the pure thermistor reading with offsets
taken into account.
12. ADJUST DEFROST INTERVAL: 1-12 HOURS
This will adjust the interval between defrosts from
1-12 hours. Adjusting from the factory settings may
cause undesired temperature.
13. ADJUST DEFROST DURATION: 5-99 MINUTES
The length of the defrost can be adjusted 5-99
minutes long. the other defrost parameters still
apply. Lengthening a defrost may cause higher than
normal temperatures.
