Constant Pressure Control Options with eRED
Constant Pressure Controls: For constant pressure control applications,
the S&P constant pressure control package is available. This package
includes the components that are needed to complete a demand-based
exhaust ventilation system for kitchens, bathrooms, and/or clothes dryer
exhaust in multi-story buildings.
S&P recognized that the programming procedure for many constant pressure
controls can be challenging, so this package is the simplest system available.
The control box can be easily installed in the eld, either mounted on a curb
or inside the building. The backlit LCD display and pressure transducer are
pre-programmed to work together to increase or reduce the speed of the
fan to accommodate for the actual demand.
Potentiometer Shipped Loose: If a variable rate that is manually changed
by the operator from the occupied space is desired, the potentiometer is
shipped loose and eld installed in the appropriate accessible location. Simply
rotating the dial will vary the speed of the fan from 20% to 100% full speed.
