Honeywell S7800A1001 Keyboard Display Module for 7800 SERIES Burner Controls
The Honeywell S7800A1001 is a Series 5 keyboard display module for Honeywell 7800 SERIES relay modules. Its 2 × 20 character screen shows burner sequence and timing, hold and lockout status, flame signal strength and first-out diagnostics. It handles local or remote annunciation and remote reset, and supports ModBus communication once that feature is enabled.
Compatible with: Honeywell 7800 SERIES burner controls.
Highlights
- Keeps a history of the six most recent faults along with total cycles and run hours.
- A pass-code protected Call Service message of up to three screens can replace the lockout display.
- Runs either the expanded annunciator or ModBus, so add an S7810M1003 ModBus Module (sold separately) when a job needs both.
- Snaps onto the relay module by two interlocking ears, and the two supplied screws hold it on a panel door.
- Wall or remote mounting takes the 203765 bracket or the 205321B flush mount kit, both sold separately.
- It is not weathertight alone; a 204718 NEMA 4 cover, A or C version (sold separately), gives a UL NEMA 4 rating.
