Cooling Mode

The cooling mode determines whether refrigeration is in Auto mode, On, or
Off. Normally the cooling mode is set to Auto mode. In the Auto mode, the re-
frigeration is 'On' below approximately 60°C. Note: If the fluid is cooling
from above 60°C, the refrigeration turns on at approximately 59°C. If the fluid
is heating from below 60°C, the refrigeration shuts off at 60°C. If the set point
is more than 5°C higher than the current bath temperature, the refrigeration will
automatically shut off until needed to maintain the temperature selected. There
may be times when Auto mode is undesirable. In that case, the refrigeration
may be set to On or Off. When the refrigeration is set to On or Off, the refriger-
ation is on or off for all temperatures.
CAUTION: The refrigeration may be damaged or the lifetime shortened if
used above 60°C for more than one hour.
