Control console is fully wired and includes advanced microprocessor-based digital control， a solid-state power module， on/off circuit breaker and thermocouple input jack. Includes microprocessor- based PID control (proportional， integral， derivative)， single segment， single setpoint， 1 ramp to setpoint. Built-in adjustable high limit overtemperature protection. Simultaneous LED display of actual temperature vs. setpoint. May be configured to display temperature in either C or F.

Option P 1200C Digital Single Program， Multiple Segment Programmable Controller

Control console is fully wired and includes advanced microprocessor-based digital control， a solid-state power module， on/off circuit breaker and thermocouple input jack. Includes microprocessor- based PID control (proportional， integral， derivative)， with single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control. Built-in adjustable high limit overtemperature protection. Simultaneous LED display of actual temperature vs. setpoint. May be configured to display temperature in either C or F.

Option B Overtemperature Control (OTC)

Adjustable digital overtemperature control， factory installed on selected control consoles with “B” suffix designation; see chart. Protects furnace and load in the event of primary control circuit failure. Overrides main controller and shuts off power to furnace if high limit is reached. Manual re-set required for safety. Operates via magnetic contacts through signal from independent thermocouple.

Optional RS485 Digital Communications Port

RS485 Digital communications port available as an option. Allows controller to be connected to a PC for remote monitoring and control of the furnace. Up to 30 units can be connected to one PC.
