THERMISTOR 1 — ZONE
This shows the pure thermistor reading with no offsets
taken into account.
2.
THERMISTOR 2 — EVAPORATOR
This shows the pure thermistor reading with no offsets
taken into account.
3. Does not apply to this model.
4. Does not apply to this model.
5.
THERMISTOR 1 — ZONE OFFSET
(DO NOT MAKE AN ADJUSTMENT TO THIS WITHOUT
CONTACTING TECH LINE: 800-779-2547)
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 temperature down below the set point.
(example: adjusting from 0 to +2 will drop the unit
temperature 2 degrees)
6.
THERMISTOR 2 — EVAPORATOR OFFSET
(DO NOT MAKE AN ADJUSTMENT TO THIS WITHOUT
CONTACTING TECH LINE: 800-779-2547)
7. Does not apply to this model.
8. Does not apply to this model.
9.
THERMISTOR 2 — SET POINT MINUS OFFSET
This shows the thermistor reading with offsets taken
into account.
10. Does not apply to this model.
11. Does not apply to this model.
12.
ADJUST DEFROST INTERVAL — 3 TO 24
HOURS
This will adjust the interval between defrosts from
3 to 24 hours. Adjusting from the factory settings
may cause undesired temperature in the refrigerator
section.
13.
ADJUST DEFROST DURATION — 0 TO 99
MINUTES
The length of the defrost can be adjusted 0 to 99
minutes long. The other defrost parameters still apply.
Lengthening a defrost may cause higher than normal
temperatures in the refrigerator section.
14.
VIEW ERROR LOG
A list of errors in the order they occurred will scroll
on the display. All errors are logged in memory. Only
door error is displayed on the display and has an
audible signal.
E0:
Door 1 (upper) open.
E1:
Thermistor 1 open.
E2:
Thermistor 2 open.
