control & troubleshooting

Any commercial HVAC system delivering more than 2,000 CFM requires a means of detecting smoke and shutting the unit down. I have extensive experience installing these detectors in multiple configurations, including equipment-dedicated, site-linked through the fire alarm panel, and equipment-linked through series shutdown connections. I also have experience installing optional accessories such as remote test stations and alarm horns. This combined experience allows me to effectively retrofit existing smoke detector systems and troubleshoot them when needed.

Many commercial HVAC systems rely on EMS boards for remote control instead of local thermostats. I have hands-on experience configuring Surveyor UCBs and installing the in-unit sensors necessary to support operating sequences and monitoring functions. I am also trained in the commissioning of these remotely controlled units, including coordination with the technical support hotline when required.

ASHRAE 62 outlines outside air (OA) requirements for acceptable indoor air quality in commercial buildings. I have both the technical expertise and academic knowledge to determine required CFM through the Ventilation Rate Procedure and then adjust economizer parameters accordingly. Most of my hands-on experience is with Johnson Controls economizer controller model SE-ECO1001-1 and Carrier/Honeywell controller model HH63AW001.
