I am looking for a Reliable;with good technical support-

Controls Manufacture that offers a packaged DDC Controls System to replace an existing 5 zone old/worn out Multi-Zone system.

Thanks, Chet

I've probably done 200+ multizone units first using ALC then transitioning to Delta Controls (the majority). Like Reliable the UO of Delta was extremely flexible. Each Delta MZU had 1 BACnet/IP card (DSC) with a BACnet MSTP subnet doing all the zones. Some of the larger units had 20+ zones, the smaller ones had 5-7 zones. The new ALC Me controllers would work nice bu the $$$ is high (specially for the BACnet/Ethernet model). All Delta DSC and DAC controllers (VAV on the way) have BACnet/IP available now. Makes for one of the fasted and largest bandwidth networks. Also imagine the size of a network you could have with just a BACnet/Ethernet controller network.

Why not use a MACH2 or MACHPro? My bad I though you posted working with Reliable, not looking for. Reliable controls have some nice hardware too.

I am not familiar with MACH2 or MACHPro, What manufacturer produces these products, as fas as Delta, I never used Delta either so which one do recommend over all for a Hot & Cold Deck Multi-Zone Application?

Thank You, Chet

Reliable Controls produces the MACH line of controllers.

I have worked for multiply contractors of both Delta and Reliable and if I could rep one it would be Delta. Reliable has some very nice hardware but their software is a little lacking for the more sophisticated clients/projects.

The last multi-zone I worked on was standalone and we used a Delta DSC and their touchscreen for the user interface. Customer liked it so much we got the change out of the rest of the facility (existing system was less then 3 years old). Was up there yesterday swapping over the boiler plant and a couple more air handlers. Installed another touchscreen in the main mechanical room and will be bringing in the existing MZU next week. In the near future the new DHMI the client will even be able to view the system via the embedded webserver as long as they have interwebby connectivity (even set up your own wireless network for the client).

Chet if you are looking for a solution like this contact me via email (in my profile).
