OVERVIEW
The ZP6-ESP-PRO is a residential and light commercial forced air zone control systems that allows
a single HVAC unit to have up to 6 separate zones. The system can be expanded to as many as 12
zones by adding 3-zone expansion panels. The panel can be used with single stage or multi-stage
heat/cool equipment as well as heat pump and duel fuel systems having up to 4 stages of heating
and 2 stages of cooling. Simple slide switch congurations allow for a wide range of system setup
and control options best suited for each zoning application. The ZP6-ESP-PRO incorporates an
integrated ESP static pressure control logic designed to eliminate the need for a conventional
bypass damper when used with 3-wire zone dampers. A Graphics Display Module (GDM) allows
real time monitoring of discharge air, return air and outside air temperature when used with
appropriate sensors. The GDM is also used to set high and low limits, high and low outdoor
balance points, timed upstaging and selection of designated ESP zones.
SEQUENCE OF OPERATION
Each zone is controlled by its own space thermostat and motorized zone damper. If any zone
thermostat calls for heating or cooling, the zones not calling will have their dampers powered
closed and the zones calling will have their dampers powered open. The heating or cooling
equipment will be brought on at the same time. When all zones are satised, the heating or
cooling equipment turns off. Zone dampers then reposition based on ventilation mode selection.
The system can be set up to operate in either Cooling Priority or Majority Wins mode of
operation.
COOLING PRIORITY:
When zones call for heating and cooling at the same time, cooling will receive priority and the
system will operate in the cooling mode until all cooling calls are satised and then automatically
change over to satisfy heating calls.
MAJORITY WINS:
If more zones call for heating than cooling, the system will be in the heating mode. If more zones
call for cooling than heating, the system will be in the cooling mode. If the number of heating and
cooling calls are equal, cooling wins.
DESIGN AND INSTALLATION GUIDLINES
2
[ ] Zone control begins with good HVAC design.
[ ] Proper load calculations used to determine duct and equipment sizing are essential in achieving
optimum performance.
[ ] Install zone thermostats in their respective zones.
[ ] System wires should be tagged to match the panel terminal designations and zone
identication.
[ ] Zone dampers should be installed at least 10’ back from discharge air grills whenever possible.
[ ] Zone dampers need to be located where they can be accessed for trouble shooting.
[ ] Flex or lined duct is recommended on the last 5’ of each branch run.
[ ] Thermostats and zone dampers can typically be located up to 300’ from the control panel when
18AWG copper thermostat wire is used.
[ ] Always use a separate 24VAC transformer rated at the proper VA to power the panel, zone
dampers and thermostats.
[ ] Never use the equipment transformer regardless of its VA rating.
[ ] When using forced air zoning with a variable speed HVAC system, high speed fan should be set
at 400 CFM per ton of cooling.

SYSTEM WIRING
DS/BK Terminals
The HVAC SYSTEM terminals have a DS/BK output. The DS/BK terminal is used with a variable-
speed fan. Connect the HVAC equipment DS, BK, ODD, or DHUM terminal to the DS/BK terminal
on the ZP6-ESP-PRO panel. Based on the DS/BK selector switch settings, this terminal will be de-
energized when the number of zones calling are less than or equal to the switch selection. This
will reduce the blower speed on most variable speed blowers.
HUM Terminals
The HVAC SYSTEM terminals have a set of normally open dry contact HUM terminals. These
terminals can be used with a thermostat wired to Zone 1 that has a humidication output
designed to control a powered or non-powered humidier. Refer to the specic thermostat manual
for humidication control.
DHUM Terminals
The HVAC SYSTEM terminals have a set of normally open dry contact DHUM terminals. These
terminals can be used with a thermostat wired to Zone 1 that has an output for a dehumidier or
ventilator. Refer to the specic thermostat manual for dehumidication control.

SPS Terminals
The SPS terminals 2 and 3 wire to the ZPA-SPS Static Pressure sensor. The sensor should be
installed on a at surface so that the diaphragm is in the vertical position. Use the 1/4” x 36”
tubing provided and connect one end to the (P1+) high pressure tting on the sensor. The other
end of the tubing should be connected to the plastic sensing probe mounted in the main
discharge air plenum prior to any zone dampers or duct transitions. The sensing probe is 2-1/8” x
1/4” O.D. Install and mount the probe with the arrow in the direction of airow. The pressure
sensor is factory set for 0.35” W.C. but is fully adjustable from 0.08 to 1.2” W.C. The terminals are
not polarity sensitive. Use 18-2 thermostat wire. After removing the outer jacket, strip
approximately 1/8” insulation off of each wire. Land the wires to terminals 2 and 3 on the
pressure sensor and repeat the process on the other end by landing the wires to the SPS terminals
2 and 3 on the panel.
NOTE: The ESP function only works with 3-wire, power open / power close dampers.

How ESP works
As zone dampers open and close, the ZPA-SPS Static Pressure Sensor continuously monitors the
system static pressure. If the static pressure goes above the static pressure setpoint, the sensor will
send a signal to the panel which will begin to open selected non-calling zone dampers until the
static pressure setpoint is maintained. The SPS LED will come on until the static pressure reaches
setpoint and then turns off. Selected non-calling ESP zone LEDs will blink when their dampers are
in a oating position. The small amount of air allowed to bleed into non-calling zones eliminates
air noise and ensures proper airow through the HVAC system. This also prevents coil freeze up
and high temperature issues. When all zones are satised, all zone dampers will go to the full
open position provided no thermostat is calling for ventilation mode.

ADDING 3-ZONE EXPANSION PANELS
The ZP6-ESP-EP Expansion Panel is a 3-zone module. It is mounted in its own enclosure to match
the ZP6-ESP-PRO master panel. The ZP6-ESP-EP connects to the ZP6-ESP-PRO panel via an included
communications ribbon connector. Another ZP6-ESP-EP can be daisy chained together in the same
enclosure to provide an additional 3 zones for a total of 12.
1. When adding the expansion panel, make sure that all 24 volt power is turned off.
2. Mount the ZP6-ESP-EP no more than 2 inches under the ZP6-ESP-PRO master panel. This will
allow enough room to facilitate wiring and connection of the communications ribbon connector.
3. Each ZP6-ESP-EP receives 24 volt from the main panel transformer. Make sure that 24 volt
common and hot match.
4. Zone thermostats and dampers wire the same as on the ZP6-ESP-PRO panel.
5. If only one ZP6-ESP-EP is added to the ZP6-ESP-PRO panel, set the Expansion Panel Selector
Switch to ‘A’.
6. If a second ZP6-ESP-EP is added, set its Expansion Panel Selector Switch to ‘B’.
Never connect or disconnect the communications ribbon connector when there is 24 volt
power present as this can cause permanent damage to the microprocessor.

The ZP6-ESP-PRO panel has a row of slide switches that are used to congure the panel for the
specic equipment application. The switches also provide other control options.
System Conguration
Switch 1 selects the type of system. Heat Pump or Heat / Cool
Switch 2 selects the type of Heat Pump. Dual Fuel or Conventional
Switch 3 selects the heat pump reversing valve. B (Energized in Heating) or O (Energized in
cooling
Switch 4 selects the fan operation. Electric or Gas
Switch 5 selects the ventilation mode. By Zone (When no calls are taking place, allows
ventilation air only to those zones with thermostat set in continuous fan mode) or All Zones
(When no calls are taking place, allows ventilation to all zones providing one zone thermostat is in
continuous fan mode.)
Switch 6 selects the purge option. ON (Zone dampers maintain position and fan runs for 1
minute after call is satised) or OFF (No purge cycle after call is satised)
Switch 7 selects Time Share option. ON (If zones being served in either heating or cooling have
not been satised within 20 minutes and an opposite call has taken place, the system will
changeover. When that mode is satised or 20 minutes has gone by, the system will again
changeover if an opposite call exists) or OFF (No Time Share)

Capacity Control
Capacity Control can be used in multi-stage equipment applications to prevent a second stage
from energizing until a minimum number of zones are calling. Any switch or combination of
switches set in the ON position establishes the Capacity Control value. This value equals the
minimum number of zones that must be calling in the same mode before a second stage can be
energized. Capacity Control only allows for the upstaging to occur. It still requires a second stage
call from a zone thermostat or the Stage Timer to upstage the equipment.

DS/BK Control
If the HVAC system has a variable-speed fan, the DS/BK control can be used to reduce the blower
speed based on the number of zones calling. Each switch has a numerical value of 1, 2 and 3.
Any switch or combination of switches selected maintains the low speed fan operation until that
number is exceeded.
