SET MODE
Pushing the "ZONE" key will activate "SET
MODE". This will display the set-point and the
corresponding zone indicator will flash.
Temperatures can then be adjusted in that zone by
pushing the "WARMER" or "COLDER" keys. To
advance to the next zone, press the zone key again.
The set mode will remain active for five seconds
after the last key stroke.
ERROR MODE
If a zone thermistor is defective or unplugged, the
corresponding zone indicator will flash and either
"-20" or "55" will be displayed.
NOTE: To clear the error mode after a thermistor
is replaced, the unit must be turned off for ten sec-
onds, then back on.
SHUTDOWN MODE
Attempting to set temperatures warmer than con-
trol limits causes a "SHUTDOWN MODE". In
shutdown mode "--" will be displayed. All unit
functions will be suspended except the lights and
door alarm. To end shutdown mode, press the
"COLDER" key.
Baffle Operation
(700TC/I, 700BR Only)
A baffle will normally be closed until the corre-
sponding zone calls for cooling.
A baffle will default to open if the correspond-
ing thermistor is defective or unplugged.
Generally all baffles will be closed when the
compressor is off. But, if a zone is warmer
than its setpoint, and the compressor cycles off,
the baffle for that zone will remain open and
the evaporator fan will continue to run.
All baffles will be closed during defrost and the
fan delay period following a defrost.
Compressor and Evaporator Fan Operation
COMPRESSOR NOTE: The thermistor in the fol-
lowing compartments controls the compressor.
