Spring is HVAC maintenance season... think about Zone Control.

With warmer weather approaching, upstairs or certain areas of your home can become uncomfortably warm without SmartZone. HVAC zone control can make the entire home more comfortable in the hottest Summer months. 

Most homes with a single thermostat have some issues with keeping everyone, everywhere in the house comfortable.  With SmartZone, thermostats are places throughout the home to achieve comfort everywhere... and if you choose to turn off some of the areas (zones), you can even save energy.  Most importantly, however, SmartZone can make your home more comfortable than it is now.  See the slides below for how it works.

How it works...

1. SmartZone is connected to several Thermostats placed in "zones" throughout the home or building.
2. SmartZone is connected to the Air Conditioning (AC) and Heating equipment.
3. Dampers (air valves) are installed in the existing ducts that connect to room vents in the "zones."
4. SmartZone controls the AC & Heating equipment AND opens/closes dampers to control air to the zones based on the thermostats.

There is obviously a lot more to HVAC Zone control than the above bullet points.  Bypass & static pressure, duct sizing & damper leakage, thermostat & equipment types, equipment modes & changeover, compressor staging, emergency & auxiliary heat... and much more.  The good news is that SmartZone takes the guess work out of the potential complications of zoning.  Check out more about why SmartZone is the best choice here.

2016 : QUESTIONS & ANSWERS about SmartZone - D

Do the wires from the condenser-outside and the system board on the air handler connect to the terminal labeled Equipment on your install sheet ? 

Assuming you are installing zoning for the first time, the wires connecting to the equipment connector on SmartZone are the same wires that connected to the single thermostat you used to control your equipment before installing SmartZone.  The terminal labels from your thermostat should be the same or similar to those on the equipment terminal.  If you see only a Y and W terminal on the thermostat then the wires from those thermostat terminals will go to Y1 and W1 respectively on the SmartZone equipment terminal.  Your hvac equipment controls will be powered by a 24VAC transformer that should be connected to the C and Rh (or you can use the Rc instead of Rh terminal because the two are jumpered together) on the SmartZone equipment connector.  Typically the wires connecting to the SmartZone equipment terminal will come from your hvac equipment control board located in the blower cabinet.  In some installations, the Y wire is typically yellow colored  (or Y1 and Y2 if you have a multispeed system) may come from the outdoor condensing unit.   If you have a heat pump you should also have a wire (typically orange) in the W2/OB equipment terminal on SmartZone.

What is the O/B dip switch and what does O-B do?

The dip switch for O or B determines the way the refrigerant reversing valve works for cooling and heating mode.  The setting you use will be determined by the hvac equipment brand you have.   O will energize the reversing valve during the cooling mode and B will energize the reversing valve during heating.  Typically Rheem/RUUD equipment will require the dip switch to be set to B and all other brands will use O, however, check with the equipment manufacturer to be sure.

CUSTOMER EMAIL: I have a 10 year old Honeywell EMM-3 zone controller. I turned the heater on this year and nothing....The system led on the emm-3 was off, I hit the boot button and the led came on and the heater started to run but a couple of minutes later the led went off and the heater stopped.  Did this twice. Am I correct in assuming its the emm-3 that's bad?  If so I would like to replace it with one of your Ecojay zone controllers.  I have a two zone system installed around 2006.  Will your system work with the existing other components...from what I've read I assume yes.

ANSWER:   Based on the information you provided it would seem likely your EMM-3 zone controller has bit the dust.  You should check to make sure the R and C wires at theZONE PANEL TRANSFORMER connector at the bottom right corner of the zone board are securely tightened to ensure the transformer power connection wires are not loose and causing intermittent power loss.  Ecojay's ZS2X-2.0 and ZS2L-T are compatible replacements for your EMM-3. If your dampers work properly with the EMM-3 they should work the same way with Ecojay zone controls.  Same goes for your thermostats.  (Must have a COMMON wire)

What is the difference between the 2X and the 2L (SmartZone Lite)?

The 2X and 2L-T are the same functionally speaking. They are both multi-stage compatible (up to 2 cool/3 heat stages) for conventional gas/electric, heat pump and heat pump with dual fuel hvac equipment.  Both display supply air temperature, each zone's thermostat call and damper open/close states and equipment operating mode. The most significant difference is the 2X has more granularity for adjusting equipment high/low temperature limit equipment protection settings. The 2X limit settings can be adjusted in 1 degree increments and the 2L-T gives you the option of 2 fixed low and high limit temperature settings. The 2X includes a supply air temperature sensor in the box whereas the 2L can be ordered with (ZS2L-T) or without (ZS2L) a sensor. We strongly encourage ordering a supply air temperature sensor with the 2L. Do not use the sensor from your existing EMM-3.  Beyond those differences, the ZS2L-T is at a lower price point. Both zone controllers, as do all Ecojay products we offer, include a 5 year replacement warranty.

CUSTOMER EMAIL: I recently purchased and installed several of your 3 wire zone dampers using an existing control system. During the process I released the clutch and opened and closed the dampers several times for temporary operation.  Do I need to go thru a setup process?  Can the actuator figure out the damper position?

ANSWER: The actuators will "reset" themselves back to correct open and closed positions the next time they are powered by the SmartZone panel.  There is no need to adjust or configure the dampers after the clutch has been pressed and damper blade rotated.  If, however, the "u" bolt that holds the shaft is loosened then the damper blade should be oriented is in the same position as the motor (open or closed) when it is re-tightened.

Question: What would be the best settings for a Carrier 5 Ton Geothermal Unit with 3/2 Heat Cool?  Would you set all zones to HP or (Zone 1 to H2) and (Zone 2&3 to HP) and set the Ecobee zone 1 to have some or all control?

I am a little confused by this... Thanks!

ANSWER: Since the zone controller, by default, controls staging for the entire system and knows what all zone are doing you don't need to use the Ecobee on zone 1 to control staging unless you have a particular situation or preference to use it that way.  Your equipment will normally operate more efficiently under most circumstances which should translate to lower utility costs if you allow SmartZone to handle staging.

The most common practice we see with heat pump equipment using SmartZone is to use a HP thermostats on all zones.  This tends to be the least confusing way of operating the system.  One not is that you can ONLY control Em. Heat from ZONE 1.  For this reason, some people choose to use a GE stat on zones 2 - 4 to eliminates the confusion about where emergency heat can be manually controlled.  Since, most thermostats can be configured for both HP or GE operation so it is your preference. The critical step is that you set the STAT TYPE on SmartZone to the type of thermostat installed on each zone.  See INSTALL GUIDE

EMAIL QUESTION:  I have a 2 zone forced air (gas) heat/cooling system controlled via a DuroZone SWZ-SW zone controller and paired with DuroZone Multiline dampers (4) total. Current thermostats are White-Rodgers. I want to replace the current thermostats with a pair of Nest thermostats. Apparently the existing zone controller is not compatible due to the reliance on both O and B wires to tell the zone controller what mode the system is in (heat or cool). I stumbled on to this site and the recommended zone controller. Would the SmartZone 2x work in this case? If so are there any guides on installation that would make this easy to accomplish?

ANSWER: SmartZone control products are compatible with the Nest thermostat and all 24VAC hvac equipment including gas/electric, heat pumps and heat pumps with dual fuel.. You can follow the link below to view the SmartZone Installation manual on the Zoning Supply website. Please contact us by phone at 844-966-3123 or email with any questions about SmartZone installation, operation or zoning in general.

QUESTION: I have a Lennox variable speed modulating furnace. Will your system work with my furnace?

ANSWER: If your controls are 24VAC (most residential hvac systems are) the furnace should work with our SmartZone controls.  If you are not sure if you have 24VAC controls, remove your thermostat from the wall and look for wiring terminals labeled W, W1 or W2. These are the circuits that control the furnace for 24VAC systems. If you have any of these terminals on your thermostat and have wires connected to any of them your furnace is compatible with SmartZone. 

QUESTION: Can more then one damper be wired to one damper output? Have 3 zones that have 2 supply ducts each.

ANSWER: You can connect 4 spring dampers and 10 power dampers to each damper connector so you will easily be OK.  For 3 zones you will need the SmartZone ZS4X four zone controller.

Replacing old 2-wire spring damper with a high quality ecojay damper

UPDATE: March 2017 - NEW Dampers available now.  TAKE-OFF ROUND, INSERT ROUND & RECTANGLE Dampers all available now ... scroll down to see all damper models. OR click here.

Some older zone control panels have only two connectors for damper wiring (common & power-close).  These were designed when predominately 2-wire (spring open) dampers were used for zoning.  In recent years, 3-wire (power-open, power-close) dampers have become more common because of their low power consumption and higher reliability.  You might think you have to upgrade your zoning panel to accommodate for these preferable 3-wire dampers... not with Ecojay dampers and belimo actuators.  The wiring diagram below shows how to connect the Ecojay Power Damper to an older zone panel that is only designed to work with 2-wire dampers.

If you are planing to replace the zone controller with SmartZone, this diagram is NOT necessary.

The parts that make an HVAC Zoning System

Elements of Zoning

A Zoning System consists of 4 primary pieces:

1. Thermostats

2. Zoning Control Panel

3. Dampers

4. Equipment

1. Thermostats

Thermostats are used in just the same way that a typical thermostat is used except with a zoning system there is ONE thermostat located in each area or “zone.”  Instead of connecting these thermostats to the equipment like a typical application, with zoning all the thermostats are connected to the Zoning Panel.  Suggest purchasing on Amazon.com or from wherever 24VAC thermostats are sold.

2. Zoning Control Panel

sale

SmartZone-4X

Sale Price:$229.99 Original Price:$299.00

The Zoning Panel is the “brains” of the operation.  This computer-like electronic board, reads the calls from all the thermostats and makes decisions about what to energize on the equipment (heat, cool or fan) AND which dampers to open or close.  Zoning Control Panels come in MANY shapes, sizes, and colors but with SmartZone you are just selecting the number of zones)

3. Dampers

PRO-Grade Power Zone Damper (Round)

from $64.99

Not only are the thermostats connected to the Zoning Panel but so are the dampers.  A damper is to airflow in the duct like a faucet is to water in a pipe.  In other words, the damper acts like a valve in the duct system to divert air to the zones where it is needed.

4. Equipment

Finally, the Equipment is also connected to the Zoning Panel.  The equipment refers to the heating and cooling (HVAC) unit.  This can come in many shapes, sizes, and configurations.  In order to apply zoning to any equipment, the correct zoning Panel mush be chosen.  Some Zone Panels are very specific and can only be used with certain types of equipment while some are much more versatile and can be used on almost ANY type of equipment used.

---

The above four parts make up the pieces of a Zoning System, but since in a standard system you already have two of these parts (THERMOSTAT and EQUIPMENT).  The addition of a zoning system really consists of adding only two different parts, a ZONING PANEL and DAMPERS.   This makes zoning one of the easiest and affordable ways to gain the much desired improvement of comfort and efficiency.  With these parts installed properly a user can enjoy the ability for both added comfort and increased energy savings.
