The IO HVAC CONTROLS ESP-400 complete with pressure sensor is designed to work with any forced air zone control system. It is compatible with ESP conventional 24 Volt, 3-wire, floating point, motorized zone dampers and handles up to four zones. The module uses a static pressure sensor installed in the main discharge air plenum of the system.
This electronic static pressure module eliminates the need for a bypass damper when used with standard zone control panels and 3-wire zone dampers.
