## Overview

The Robertshaw 780-845 Ignition Module is a 24V intermittent pilot control designed for residential and commercial heating systems. It delivers precise ignition with a 90-second spark and 6-minute purge cycle, continuously monitors pilot flame for safety, and features an automatic retry system with a one-hour lockout to prevent malfunction. Its universal bracket and quick-connect terminals ensure easy installation and reliable 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.

Review: Worked out perfectly.
Review: The Robertshaw ignition module worked great and the replacement from a Lennox SP 745 was straight forward. The wire positions are not all in the same spot so you will need to make note of this as you disconnect the old module. The ignition terminal on the Robertshaw is labeled SPARK, this is the only difference for labelling. The screws that came with kit were a bit too short so I used a more suitable length. My furnace now works great again, I am very happy with the product which saved me a lot of money in the end.

It was easy to install although I had to drill a few holes on the bracket of the furnace. Just keep track of the wires and where they go.
