3 OPERATION WITH THE TIMER
The 2132 or 2116 can be used as a process timer allowing timed heating or timed delay,
according to the options in the table. There are 5 timer modes, but 2 of them are affected by
whether the setpoint ramp rate feature is being used, making 7 entries in the table. The table also
shows the status of the Timer Light on the controller. A visual impression of the different modes
is given in fig 3.
