Heating systems: Freely programmable large size application (Excel 800)
 |
This solution example provides control of a multi boiler sequence, including
| • |
2-stage burner control with alarm input |
| • |
boiler return water control (incl. return water temperature minimum limitation) |
| • |
sensors for boiler temperature and boiler return water temperature |
| • |
boiler safety thermostat |
| • |
boiler pump control and alarm |
| • |
sensor for common supply water temperature |
| • |
boiler strategy incl. boiler sequence cycling |
| • |
general emergency-off input |
|
| In addition integration with Honeywell and 3rd party LonWorks(R) systems is possible. Excel 800 supports 512 NV's and is LONMARK compliant. |
| Physical I/O's can be Honeywell Excel 800 Panel I/O's, Excel 800 LON I/O's, Smart I/O's or 3rd party LonWorks(R) devices. |
| Depending on the need for LonWorks interoperability with 3rd party devices, Excel 800 can typically control 170 physical I/O's or more. |
Honeywell Excel 800 Panel I/O's offer the unique benefit of
| • |
Plug and Play: electronic module can be exchanged without the need to switch off power supply, automatic software update, configuration and start-up |
| • |
Fast and easy wiring due to connector bridges, push-in wiring terminals, cross connectors and auxiliary terminals |
|
Honeywell Smart I/O's offer the unique benefit of
| • |
230 Vac or 24Vac versions |
| • |
various point mixes |
| • |
fixed or removable terminals |
