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 H32 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 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 H32 can be controlled by conventional single stage or heat pump

thermostats. Each thermostat can then call for heating, cooling or the

fan. This panel can control single stage gas-oil-electric heating and

cooling, two stage heating and cooling and most heat pumps. This

panel can control two stage/speed and dual/fossil fuel heat pumps.

When 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 H32 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 H32 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 H32 will also activate the W2

for second stage heating. The Second Stage Timer is adjustable

between 5 to 25 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

H32 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 H32 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.

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 operates as first stage cooling only. 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 activate

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 EH 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 any time 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.

aving 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. 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.
