Air handling units: Freely programmable mid size application (Excel 50)
 |
This example solution provides control of
| • |
2-stage supply and return fan with differential pressure supervision |
| • |
mixing air dampers |
| • |
air filter with differential pressure supervision |
| • |
hydronic heating coil with return water valve and bypass, pump and pump alarm |
| • |
hydronic cooling coil with return water mixing valve, pump and pump alarm |
| • |
frost protection thermostat |
| • |
temperature sensors for outside air, supply air and return air |
| • |
digital wall module (room temperature setpoint adjustment, room temperature display, occupancy overwrite) |
| • |
energy management functionalities like Optimum start/stop, night purge, maximum load demand management and many others |
|
| In addition integration with Honeywell and 3rd party LonWorks(R) systems is possible |
| Excel 50 supports 46 NVs and is LONMARK compliant |
|
| Hardware inputs |
