INSTALLATION
The H32P Control is a three (3) zone control panel that can be
used with conventional single stage and two stage heating and
cooling, heat pumps with or without dual fuel and two speed
heat pumps for up to three stages of heating. The H32P panel is
the central control panel that all zone dampers, zone
thermostats, Heat Pump Controls, power transformer, Outdoor
Air (OAS) and Leaving Air Sensor (ZPS) are wired.
When installing the H32P panel it is important to pick a central
location where it is most convenient to bring all the wires. Most
often this is at the furnace or air handler. It is often the most
convenient location and closest to power, the HVAC unit
controls and the zone dampers when typically located at or near
the plenum.
The H32P panel case is made of sturdy ABS plastic and can be
mounted to any flat surface. It is recommended that the panel
be mounted to a wall or return plenum and NOT on the furnace
or plenum where it will be in contact with the excessive hot
temperatures.. The panel can be located in an attic space or in
an enclosed cabinet of a rooftop unit. Insure the panel is not in
direct exposure to the elements.
The cover easily removes from the case by pulling firmly and
separating the cover from the case exposing the circuit board.
There are 4 key-hole mounting points in each corner of the case.

The case has openings in the rear of the case as well as the side
for all wiring. Wiring can come from the back as well as the side
in order to make a neat installation.
OPERATION
The H32P can be controlled by conventional single stage or
heat pump thermostats. Each thermostat can then call for
heating, cooling or the fan. When a thermostat calls the panel
will keep open the damper to the calling zone, if not already
open, close the dampers to the zone(s) not calling and activate
the appropriate HVAC equipment. When opposite calls exist
for both heating and cooling the panel will allow the zones to
automatically switch between the modes. When all zones are
satisfied the panel then looks for individual fan calls from any
zone and controls the dampers based on these calls as well.
When all zone thermostats are not calling for heating, cooling or
the fan all dampers will return to a normally open position.
Once a call for either heating or cooling is made the panel will
open the damper(s) to the zone(s) calling, close the damper(s)
to those zones not calling, activate the appropriate controls for
heating or cooling, whichever is being called and not accept any
calls for the opposite mode.
Any calls for the opposite mode will be locked out until the
initial mode is either satisfied or a period of time has elapsed
that is sufficient for the first mode to satisfy, a maximum of 20
minutes. A unique sequence determines the time the unit has
been running or needs to continue to run in order to adequately
provide conditioning for each mode. If a particular mode has
already been calling for 20 minutes or longer and an opposite
call comes in the H32P will immediately drop the mode, enter
the purge mode in order to dissipate the conditioned air into the
zones calling before switching over to provide the new
conditioning call to its zones.
When using the H32P to control two stage heating, the second
stage is controlled based upon time after the first stage call from
the thermostat. When any zone calls the panel’s built-in timer
begins and after the set period of time elapses the H32P will
also activate the W2 for second stage heating. The Second
Stage Timer is adjustable between 2, 4, 8 or 16 minutes after the
first stage calls. Once the second stage is on, it will continue to
run until the first stage is satisfied.
Once all zone thermostats are satisfied for heating and cooling,
the H32P can now accept Fan calls allowing Continuous Air
Circulation(CAC) in those zones where the thermostat’s Fan
Switch is set to ON. These zone dampers will be Open while
the dampers to the zones where the Fan Switch is set to AUTO
will be CLOSED.
When all zone thermostats are satisfied for both Heating and
Cooling, and all Fan switches are set to AUTO position, the
HVAC unit will be off and all zone dampers will return to a
normally open position. Once a zone calls for heating, cooling
or fan, the dampers to the calling zones remain open and the
dampers to the zones not calling will close.
Set-Up for Various HVAC Equipment
The H32P is factory set for conventional heating and cooling
operation. The panel only needs to be configured when using
with an electric furnace or heat pumps.
Most all of the panel configuration is done by setting the DIP
switches in the top right of the panel. Other functions come by
wiring for specific applications. Below is shown the most typical
settings. Review each function for you application.
SYSTEM – G/E OR HP This switch sets the HVAC Output
operation. In G/E the Y1 makes as a Cool call and W1 as a
Heat call. In HP position Y1 makes as the compressor call for
both heating and cooling.
HP Type – CONV or FF – This switch is used to determine the
equipment output when the System switch is set to HP , this
switch determines if the output will be for a conventional heat
pump with electric back-up heat or fossil (dual) fuel mode.
FAN IN HEAT – YES or NO – This switch will activates the Fan
on a call for Heat in the Yes position. In Off, the heating unit
must activates the fan when the heat is called.
FAN PURGE – YES or NO – This switch determine if the Fan is
kept on during the Purge Mode, after the end of each heat or
cool call.
STAT RV – O or B – When using HP type thermostats this
determines if the O or B terminal is wired to the W/OB terminal
on each thermostat to determine if the call if for Heat (B) or
Cool (O).
TSTAT – HC-HP Switch determines if conventional Heat/Cool
thermostats or Heat Pump thermostats are being used for ALL
zones. A conventional HC stat would have separate W and Y
output for heating and cooling calls. A HP thermostat uses Y for
both a heat and cool call and the O or B is used to determine
whether the call is for Cooling (O) or Heating (B).
EM HEAT – This switch sets any heat call to call for the
Emergency Heat. The Red EM HEAT LED on the panel will light
only when this switch is ON. This is used when there is no Emer
Heat switch on the thermostats.
TEST – This switch accelerates the panel timings in order to
provide a quick checkout of all of the functions without having
to wait the full time for each sequence.
One of the many features of the DIP switches is if at anytime the
equipment is changed from single stage to heat pump or vice
versa the thermostats do not need to be changed with the
equipment change. Changing the DIP switch settings is all that
is needed.
Leaving Air and Outdoor Air Sensor
The Leaving Air Sensor, Model ZPS, is a remote sensor that is
located in the supply air duct to sense the Leaving Air
temperature of the HVAC Unit. The ZPS is a high limit
protection for the heating and a low limit protection for the
cooling. When zoning, the airflow through the HVAC Unit is
critical. The ZPS protects the equipment in low air flow
situations as well as when by-pass air is being directed back into
the return air duct.
The heating limit is adjustable from 110°F to 170°F. The cooling
limit is fixed at 45°F. When the ZPS senses heating above its set
point, or cooling below its set point, the H32P will drop both all
stages of heating or cooling. The ZPS must sense a 10°F fall for
heating or rise for cooling before re-activating the first stages of
heating or cooling. If two stage heating or cooling is being used
the second stage timer will start again once the first stage is re-
activated.

Outdoor Air Sensor - OAS
The Outdoor Air Sensor is used only when using a Heat Pump
with Dual/Fossil Fuel back-up furnaces. The OAS senses the
outdoor air temperature and switches the heating control
between the heat pump and the fossil fuel furnace. The
temperature set point for this is adjustable on the Outdoor
Balance Point (OBP) dial on the control panel. It is adjustable
from 5°F to 53°F. It is suggested that this be set just above
freezing to avoid the heat pump from potentially going into
Defrost mode.

Stage Timer
The H32P has a built-in stage timer that eliminates the need and
added cost of using two stage thermostats. On a call for either
heating or cooling the timer begins. Setting the Stage Timer dial
provides a adjustable time delay of 5 to 21 minutes between the
first and second stage calls and the same between a second
stage and third stage call of heating, if used.

STAGE TIMER
PURGE TIME
The H32P has a built-in Purge Time after each call is satisfied
and provides a minimum off time before another call is initiated.
The Purge Time is set at 2 minutes after all calls for a particular
mode are satisfied or when the Changeover Timer requires a
changeover due to opposing calls.
After all calls are satisfied or the changeover timer activates, the
Purge Timer begins and the heating or cooling, whichever was
on, is deactivated. Typically the fan may be running during this
time and the damper(s) to the last zone(s) calling will remain
open to purge the conditioned air only into those zones that
were calling for the conditioning. DIP Switch 5 can be set ON
to keep the Fan running during the Purge mode in order to
prevent the fan cycling off and back on between modes. In the
instance where the Fan staying may create a draft, and the
frequency of opposite calls is minimal this switch can be kept to
OFF.
Minimum On Timer
The H32P also has a minimum on time whenever the
compressor operates in order to prevent frequent short cycling.
Once there is a call for cooling or the compressor on a heat
pump, the H32P will hold that call for a period of 2 minutes.
CHANGEOVER TIMER
Whenever a call is made for either heating or cooling, the
changeover timer is activated in order to track the amount of
time heating or cooling is on. When an opposite call is made
after a first call is existing the changeover timer calculates the
amount of time the unit has already been supplying the first
mode in order to determine how long it will hold off the
opposite call. If an opposite call is made shortly after the first
call, the opposite call may be held off for as much as 20
minutes. If the first call or subsequent calls for the first call
mode has had that mode operating for up to 20 minutes already
and an opposite call comes in after 20 minutes, the changeover
timer will immediately recognize the opposite call, shutting off
the current mode, enter the purge mode and automatically
switch to the opposite mode.
The longer a call has been running up to 20 minutes, the shorter
the wait time will be for an opposite call. If a call is over 20
minutes and an opposite call is made the changeover will be
immediate following the purge time. This intelligent changeover
timing makes the H32P unique to any other zoning system.
CHECKOUT
The H32P has unique features that simplify the checkout of the
system and has LED readouts that constantly indicate the system
operation. Once 24 Volt Power is applied to the panel the
Green Power LED will illuminate. This will stay illuminated
constantly when power is applied.
The System LED will provide several different indications based
upon color and if it is flashing.
Heat ON – RED
Heat Limit – RED Flashing
Cool ON - GREEN
Cool Limit - GREEN Flashing
FAN ON - AMBER
PURGE - AMBER Flashing
Each zone has its own small Green indicator LED next to each
zone relay. This light is lit when the specific zoning is calling for
the mode shown on the System LED.
WIRING
The H32P is very simple to wire and requires only a minimum
number of connections. The H32P terminal blocks are color
coded and screw-less for all wires to be easily pushed into their
respective terminal by de-pressing the button for each point and
releasing once the wire is seated. (Solid wire can often just be
pushed into the terminal without de-pressing the button.) To
remove the wire, just press its button again and remove the
wire.
Zone Dampers – The H32PP provides Dc power to
ZONEFIRST’s exclusive Plug-In Zone Dampers. These dampers
use a modular cord, supplied with each damper and is
complete with RJ11 jacks on each end of a 25’ cable for each
zone damper. Up to 10 dampers can be wired to each zone.
The panel has a GREEN LED to indicate when the damper
should be open.

TROUBLESHOOTING
The H32P is a very simple control to troubleshoot, especially
with the LED indicators. The only other device needed is a
simple Volt/Ohm meter. Almost all problems can be traced to
an external component or wiring to the H32P. The following
procedures can help isolate the problem.
Zone(s) Not Calling
Each zone has a Green LED next to the zone relay when it is
calling and that calling is being recognized by the H32P. If a
zone is supposed to be calling and the Zone LED is not on,
check for 24VAC across the thermostat terminal C and the Y, if
a Cool call, W if a Heat Call, or G if a Fan call. If there is no
voltage here at the panel the panel is not getting the signal from
the thermostat. The problem is mis-wiring, a broken wire or a
problem in the thermostat. To check the zone on the panel,
place jumper from R to Y, R to W or R to G to see that the panel
is operating properly.

FORM 320251-0803 ©2007 ZONEFIRST™6
Zone(s) Will Not Shut Off
If a zone will not stop calling, the Zone LED should still be on.
Depending on the call disconnect the Y, W or G wire from the
terminal strip. The zone will drop out. Check the thermostat
wiring for a mis-wiring or short that keeps the zone calling.
Damper Motor Checkout
To checkout the dampers, the panel has a GREEN LED for each
zone. This illuminates when the dampers are to be OPEN,
either on a call or when all zones are satisifed. The damper
position is confirmed by the bi-color LED on the motor. When
the panel is Green, the motor LED must be Green also
indicating the damper being open. When the panel LED is not
lit the motor should be closed and this is confirmed by the
damper LED being Red.
