Make-up Air Controls

An optional microprocessor controller that is factory programmed, wired, and tested prior to shipment. The controller can operate stand-alone or integrated with a Building Management System (BMS) using BACnet MS/TP or IP, or Modbus RTU or IP protocols. This controller is responsible for operating the unit in a safe and energy efficient manner while controlling temperature.

End-users no longer need physical access to the unit mounted microprocessor to adjust control point parameters. The optional remote interface displays and allows control point parameters to be adjusted. The remote interface is available as an accessory to the microprocessor or network interface.

Indirect gas-fired furnace units come with a standalone furnace controller. The furnace control has a keypad and easy-to-read LCD display allowing users to adjust all set points, lockouts and delays. It includes a furnace-commissioning menu with preprogrammed steps through the furnace start-up. The controller monitors furnace operations for alarm conditions. The unit will record the alarm description, time, date, available temperatures and furnace status for the user. The furnace control also reserves a digital output for remote alarm indication.

The optional remote panel makes field wiring between the remote panel and unit easier. Labels are the same for terminals on the remote panel and unit (example: R to R, G to G, etc.). What's more, switches on the remote panel replace the need for someone in the field to provide contacts for fan enable, heat enable and cooling enable. Indicator lights for operation, warnings and alarms are available options on the remote panels. Remote panels fit in NEMA rated enclosures (1, 2, 3, 3R, 4, 4X and 12) for many applications.
