INTRODUCTION TO ZONING
Static regain zones better than conventional3 ways to zone
1. Variable CFM out of the blower to match Static Pressure / Zones calling
2. Bypass excess air• Bypass to a dump zone• Bypass to return
3. Increase the number of outlets in each zone
04/22/23 10ZONING SOLUTIONS
The Realities of Zoning Success
• Increased Available Supply static pressure when Low load zones satisfy
• Increased Branch duct velocity delivers Colder, Dryer air (more BTU’s to the space) when available supply static increases.
• Decrease in coil velocity increases BTU/CFM transfer
• Coil icing issues only occur when set point is not achieved causing extended cycle time.

Market Impact
• High efficiency equipment can be made even more efficient with the power of zoning.
• Airflow can be manipulated based on zone weight so we have a lesser need for bypass which impact actual delivered efficiency.
04/22/23 26ZONING SOLUTIONS
Market Impact• Humidity Control comfort is not just about
temperature. Humidity has a large impact on how comfortable we feel.
• The Zone Pak Pro™ provides systems for humidification and positive control of the bypass humidifier duct.
• The Zone Pak Pro™ allows you to run a dehumidification cycle using standard equipment. You no longer need equipment with a dedicated “Dehum” cycle. Fight moisture build up and mold in humid climates. Keep everyone more comfortable.
04/22/23 27ZONING SOLUTIONS
Market Impact
• Zoning makes any system more effective– This is especially true for heat pumps that can at times be
capacity limited. Concentrating the conditioned air to those areas that need heat or cool just makes sense.
• Staging on Capacity – Presently only the highest end equipment has the
capability to adjust its capacity based not only on thermostat demand but on equipment capacity. Space Pak has taken a large step toward making heat pumps an option for more areas of the country.
04/22/23 28ZONING SOLUTIONS
Market Impact• The Zone Pak Pro™ Steps out of the 20th century and
into the 21st.– It has been designed to give contractors abilitites that
have never been available before.– It has a great new look. The LCD screen makes a
statement to today’s tech savvy consumers– It is entirely software driven. There are no dip switches.
The adaptive program walk installers and technicians through with no confusion.
– Use ANY thermostats that make sense for your application. Zones 2-4 use only 4 or 5 wire heat/cool stats. New installers will have no problems with this unit.

USING THE ACM TO SET BACK AND MATCH 2 SPEED CONDENSER
STEP # 1 – REFER TO THE CFM SET FOR MAXIMUMCONDENSER CAPACITY.
STEP # 2 – DETERMINE THE SET BACK CAPACITYOF THE CONDENSER. ALL MANUFACTURERSSET BACK A % OF TOTAL CAPACITY. SOMESET BACK 30%, 35%, 40% OR 50%.
STEP # 3 MULTIPLY THE TOTAL CFM FOR MAXIMUM CAPACITY BY THE % SET BACK. THIS WILL GIVE YOU A CFM TO SUBTRACT FROM THE TOTAL.
STEP # 4 SUBTRACT THE % CFM FROM STEP 3 FROM THE TOTAL.STEP # 5 FIND THE SET BACK CFM ON THE ACM AMP CHARTSTEP # 6 SET THE ACM BY READING AMPS TO THE MINIMUM POSITION.

Market impact
• Programmability– The Setup Wizard walks the installer through a series
of very simple setup parameters. – The setup worksheet gives the installation manager or
Comfort consultant an easy way to tell installers just how they want the system to be configured.
– Once the Setup Wizard is complete the parameters are “burned” into non-volatile memory. Loosing power will not reset your settings.

• The first time the system is powered up the Installer must run through all of the Setup questions. This sets all of the default settings.
• Subsequent times if no changes are made in 30 seconds the system will power up using it’s current default settings

Stage on Demand
• The Zone Pak Pro™ accepts two-stage inputs from the Zone 1 thermostat.
• Demand will be recognized and served.
04/22/23 54ZONING SOLUTIONS
Stage on Capacity• Heat pumps provide a finite
amount of heat or cool in any given operating mode.
• This graph shows a simple single-stage scenario. – Call starts – ∆T (the change in temperature
over any given time) increases rapidly as the refrigerant starts to circulate
– ∆T starts to decrease, finally going to zero as the equipment capacity is reached.

Zone Weighting
• Zone weighting gives The Zone Pak Pro™ several distinct advantages– We are able to stage up the air
handler independently of the condenser based on the amount of ductwork being served. This reduces or eliminates the need to bypass increasing system effectiveness.
– Priority can be based on the cumulative zone weight calling for any particular service.
04/22/23 57ZONING SOLUTIONS
Air Handler Control
• Staging the Air Handler(s) independently from the condensers gives us a very powerful tool to affect comfort.
• Only stage up the Air Handler when there is enough ductwork open to accept the air provided.– Throttle back the air handler for
dehumidification.• Controlling fan speed provides
another tool for customizing your customers’ comfort.– Provides warmer air delivery to
single zone callers.• Reduce or Eliminate the need for
bypass.

Humidification
• On a call from a humidistat:– Send a 24VAC signal to
the humidifier– Open a damper in the
humidifier bypass ductwork
• Eliminates the homeowner’s need to open or close a manual damper
04/22/23 59ZONING SOLUTIONS
Dehumidification
• Standard Equipment– On a call from a
Dehumidistat:• If cooling back off one
cooling speed setting• If not cooling start the
condenser and low speed fan
• Run the system on and off on a user defined cycle period.
– Inhibited during heating cycles
• Lennox Signature/Carrier Infinity– Pass the call to the proprietary
equipment– Inhibited during heating cycles
The Zone Pak Pro™ has the ability to operate as a whole house dehumidifier.
04/22/23 60ZONING SOLUTIONS
Built-In Controls• Balance Point Calculations – no need for an outdoor
thermostat.• Resistance Heat Lockout control holds off resistance
heat above a given temperature to comply with utility regulations or incentive programs
• Low-ambient cooling – no need for a low-ambient kit, ZPP inhibits cooling below an adjustable temperature automatically.
• Outdoor Reset Controls – adjusts Leaving Air Temperature requirements as outside air temperature changes.
• Leaving Air Controls – protects HVAC equipment04/22/23 61ZONING SOLUTIONS
Leaving Air Temperature SensorHeating
• Protects the HVAC Equipment from extreme temperatures
• Heating LAT trips 2nd stage 10oF below setpoint*, and the 1st Stage at setpoint.
•1st stage is reconnected on a temperature fall of 15o and 4 minute off-time.
•Up staging is inhibited within 15o of the setpint
•Calls that contain a W will use the Backup Heat LAT Setting
*The LAT System is a secondary control. It should be set inside factory limits.
04/22/23 62ZONING SOLUTIONS
Leaving Air Temperature SensorCooling
• Protects the coil from freezing
• Cooling LAT trips 2nd stage 5oF above setpoint*, and the 1st Stage at setpoint.
•1st Stage is reconnected after a temperature rise of 10o and 4 min off-time.
•Up staging is inhibited within 10o of the setpoint
*The LAT System is a secondary control. It should be set inside factory limits.
04/22/23 63ZONING SOLUTIONS
Equipment Integration
• The Zone Pak Pro™ has been designed with all the features you need to control virtually any heat pump.– All Electric– Dual Fuel– Geothermal
04/22/23 64ZONING SOLUTIONS
Thermostats
• Zone 1 – Use any thermostat that provides the features you need. Heat/cool or Heat pump, single or two-stage, wired or wireless. You can use the thermidistats, anything that gives you the control you want.
• Zones 2-4 Use simple 4 or 5 wire heat cool thermostats. This simplifies installation and planning.
04/22/23 65ZONING SOLUTIONS
Software Driven
• The key to the flexibility and adaptive nature of the Zone Pak Pro™ is the fact that it is 100% software driven. – Most settings and timers are field adjustable – System changes and upgrades can be sent by
email– System will be more end-user friendly
