## Overview

The Robertshaw 780-845 Ignition Module is a 24V intermittent pilot ignition control designed for residential and commercial heating systems. It delivers up to 90 seconds of spark with a 6-minute purge delay, continuously monitors pilot flame presence, and features a fail-safe lockout after three unsuccessful ignition attempts. Equipped with a universal bracket and 1/4" quick connect terminals, it ensures easy installation and reliable, safe heating performance.

## Description

When the thermostat calls for heat, the 780-845 control simultaneously initiates ignition sparking and opens the pilot valve portion of the gas valve. Pilot flame recognition stops ignition sparking and opens the main valve portion of the gas valve. Pilot burner flame is continuously monitored at a synchronous frequency for the duration of the heating cycle. Should the pilot flame fail during the heating cycle, the control will shut off the main valve until the pilot flame is established. The 780-845 lockout ignition control provides 90 seconds of spark, followed by a 6 minute time delay [purge] between ignition attempts. After three tries, if no pilot flame is sensed, the control goes into a one-hour lockout period. At the end of the lockout period, if the demand for heat is still present, the unit will repeat the three tries for ignition.
