Does anyone know of a BACnet service or device that would allow me to pull in forecasting data into my control sequence?
With out being overly long-winded here's what I'm trying to do. I have a heating system that has two dissimilar sized coal boilers. The small boiler is roughly half the size of the large boiler. Because they are coal, i.e. slow startup/long cool down, the lead/lag logic is currently pretty basic with the small boiler being the lead boiler and the large boiler being the lag. I want to use forecasted heating degree-hours to make the decision as to which boiler should be the lead and which should be lag. This would happen once per day just after midnight. If I could just get then next 24 hours of temperature forecast this would be easy enough to do.
When I Google "bacnet weather forecast" the only product that looks remotely promising is http://www.esacsrl.com/en_eBACgwMeteo.asp but I'm not sure if it pulls forecasted data or just current data. I've contacted to company that makes it to get more info.
Thanks in advance!!
