ESP 4 ZONE PANEL
ZP4-ESP
ZONE CONTROL PANEL
The ZP4-ESP is a 4 zone panel that integrates our award winning ESP technology
to completely eliminate the need to install a bypass damper. 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.
The panel can be used with single-stage, multi-stage, heat pump or dual fuel
equipment. A wide range of control options provide ultimate application
flexibility including adjustable high/low limits, adjustable high/low balance
point, and 2 zone, 2nd stage capacity control.
Static pressure sensor & panel cover included
*For ESP functionality, 3-wire MD dampers and static pressure sensor must be used
