respective LEDs constantly. The display will show the
water/glycol bath temperature.
The compressor and condenser fan will continue to
run until set temperature is reached. Once reached the
compressor and condenser fan will turn off and the
LED will change from flashing to constantly on to
display that there is power. A 2°F rise above the set
temperature will cause the compressor and condenser
fan on again. This cycle will repeat as required
depending on load.
Power Interruption
During a power interruption the control will resume
from the point of interruption when power is reapplied
and the time delay expires. Any switches/components
that were energized when power was interrupted will
be energized when power is reapplied.
Error Codes
E3 = Water/Glycol mix too low, add mix
E4 = Water/Glycol temp too high (>45°F)
E6 = High refrigeration temperature
NOTE: Error codes will display until corrected.
