In Denver, Colorado, Lowell 17 provides mechanical and HVAC maintenance services for an eight-story, mixed-use medical building that provides community health services along with long-term care and rehabilitation services. The building had an out-of-date controller failure for one of their 100% makeup air units. It was a critical concern and they needed to be up and running the next day. They worked with partner Holbrook Service and chose Desigo PXC controllers from Siemens to automate their building controls.

For this medical building, specialized applications require even more specialized implementations, which is why Lowell 17’s controls partner, Holbrook Service (David Carpenter), recommended Desigo PXC4 controllers from Siemens.
Desigo controllers have some deciding factors:

• Modular – Carpenter appreciates that the PXC4 comes with 16 onboard points with the ability to add modules up to 40 total points based on what the site and customer need. 
• Block programming – Significantly faster, more efficient, easier programming compared to competitive controllers. For Holbrook Service, programming of this nature means engineers can see live data and live debugging as the logic operates.
  
• Live downloads and program changes – Downloads and program changes can happen in real time without rebooting or cycling equipment, which reduces equipment downtime and is particularly important in medical facilities like this one.
