Today's Zone Controls - No longer your Dad's old relay boards.

Today's Zone Controls -  No longer your Dad's old relay boards.

As featured in SupplyHouse Times October 2020 issue, our very own Dan Firkus discusses how today's zone controls have come a long way from the days when controls were literally “relays on a board.” 

Today’s zone controls have come a long way from the days when controls were literally “relays on a board.” Take a minute to envision the arduous task of assembling the relay board; consider the space required to locate the large number of relays that is common in today’s ever-shrinking mechanical spaces. Imagine having to provide power to each relay and combining seemingly endless end-switch wires to control the equipment. All of this could result in hours of troubleshooting if something went wrong. Thankfully, with so many great relay board control choices now available, the lives of your customers have become easier.

Relay boards offer myriad friendly capabilities, simplifying installation and service while featuring a clean appearance that compliments the craftsmanship of a professional looking installation. They contain advanced features that engineers appreciate when designing systems that incorporate sophisticated modulating boilers and air to water heat pumps, yet are simple enough to work with basic single-stage, cast iron or mid efficiency boilers.
