Over the last couple of years, many new products have been introduced to the Zone Control market that purport to reduce or eliminate the need for a bypass or dump zone pressure relief setup that has been common since the 1980s.
“Bypass Eliminator” or “Static Pressure Equalizer” … whatever you call it, the concept is basically the same no matter which company or product you are talking about. The concept IS, to leak air into NON-calling zones in order to relieve static pressure in the supply duct instead of using a bypass or a dump zone.
This idea is appealing to many who have not wanted or been able to add a bypass/dump zone but still need some pressure relief in the air system.
ECOJAY has a new solution on the market “SmartStatic”, Much like the competitors, SmartStatic is a device that automatically (based on a static pressure sensor) leaks air in the NON-calling zones to relieve air pressure when needed. The SmartStatic can be used with new installs or with any existing system that uses standard 3-wire (power open / power close) zone dampers.
ALSO, the SmartStatic can be used WITH or WITHOUT a bypass/dump damper for the ultimate flexibility and capability to control static air pressure.
iO Controls, ZoneFirst & others have similar solutions that require specialized and expensive accessories and can’t be used in conjunction with any other pressure relief methods.
SmartStatic can control up to 4 zones on each board but can be chained together to control as many zones as needed with a single static pressure sensor. This is much preferable to some of the alternative methods that use multiple sensors and adjustments that can conflict with each other.
