This series monitors the demand for heat, controls the combustion blower, monitors proper airflow, ignites and maintains the flame during heating, and provides diagnostic support. The on-board diagnostics with LED output provide assistance with troubleshooting and ensures safe and efficient burner operation. The microprocessor circuit design provides precise, repeatable timing sequences for ignition and purge times (pre-, inter-, and post-) as well as multiple tries for ignition. The optional 120/240 VAC field selectable line voltage capability provides additional field service efficiency and lower inventory costs.
