Note
The temperature control in these mod-
els is a programmable and automatic
single set point device. When the pro-
gram has ended, the controller will
maintain the chamber temperature at a
value equal to the last programmed
level (Set point 4) until the program is
canceled. It will not automatically cool
to ambient unless Set point 4 is set at
ambient. When a program is canceled,
the controller will maintain the cham-
ber temperature at a value equal to the
single set point mode set point.
