Zone Control System with built in Static Pressure Control eliminates the need for a bypass damper.
The new Zone-ESP panel incorporates both our standard zone module and our new ESP module. The modules are pre-wired together and come as a single control panel ready to install.
How it works
The system works like any standard zone control system with one exception. A static pressure sensor continuously monitors the system static pressure, and if the static goes above it’s set point the zone panel will send a signal to the dampers that are in the closed position (those not calling for heating or cooling) to start to open a small amount to keep the pressure from going above setpoint. The small amount of air that is allowed to bleed into the non-calling zones eliminates air noise and assures proper airflow.
Tests indicate that bleeding a small amount of conditioned air for a short period of time into non-calling zones has little to no impact on the zone temperature. In most cases the non-calling zones are above or below setpoint and can absorb the additional conditioned air without causing any temperature deviation.
