iO HVAC Controls ZP4-ESP-FAV 4 -Zone ESP Panel with Ventilation Control
The ZP4-ESP-FAV is a 4 zone panel that integrates our award winning ESP technology to completely eliminate the need to install a bypass damper and pairs it with a timed & demand ventilation control. This 3H/2C zone panel comes with a static pressure sensor. The system works like any standard zone control system with one exception; a static pressure sensor continuously monitors the system static pressure. If the static pressure goes above setpoint, the ESP panel will power the selected non-calling zone dampers open just enough to relieve the excess pressure. Tests indicate that bleeding a small amount of conditioned air for a short time into non-calling zones has little to no impact on the zone temperature.
