All necessary settings and setpoints are programmed into the microprocessor-based controller via
the operator interface. The controller is capable of receiving signals simultaneously from a variety
of control sources, in any combination, and priority order of control sources can be programmed.
The control source with priority determines active setpoints via the signal it sends to the control
panel. Control sources may be:
• Local operator interface (standard)
• Time of day scheduling (optional capability available from local operator interface)
• Hard-wired 4-20 mA or 2-10 Vdc signal from an external source (interface optional; control
source not supplied)
• LonTalk™ LCI-C (interface optional; control source not supplied)
