Functions
This type of controller has single ramp and dwell
programming capabilities. The Ramp and Dwell
can be configured to five different modes.
1. Mode 1 (Opt. 1) is a Ramp (if needed) to
the Setpoint temperature, a Dwell, and
then a cool down.
2. Mode 2 (Opt. 2) is the same as mode 1,
except the controller continues to heat at
the Setpoint after the Dwell has complet-
ed. (This mode does not cool down.)
3. Mode 3 (Opt. 3) is the same as mode 1,
except the Dwell time includes the Ramp
(if needed).
4. Mode 4 (Opt. 4) is the same as mode 2,
except the Dwell time includes the Ramp
(if needed).
5. Mode 5 (Opt. 5) is a Dwell (delay time)
before the controller Ramps (if needed)
to the Setpoint temperature.

the Setpoint temperature. (The controller
should be left in the Automatic mode
except when programming.)
• A program mode can be set by changing
the "tm.OP" variable to "Opt. 1, Opt. 2,
