Best damper motor (actuator) on the market... we tested them all.

Productszoning supplyComment

Well, maybe not technically ALL of them but dozens and even more than in this photo.

We narrowed down by specs that would work for us first.  Between 30 and 60 second travel time, 90 deg rotation, at least 1.5nM torque, lower than 3.5VA power consumption, 24Vac operation, clutch free movement, minimum open/close, range of 3/8" to 1/2" shaft and more.  Once we narrowed down to here we still had about 6 or 8 motors and we tested the top 5 for full 10 year accelerated life and field testing.  Some we even used in production for a while.  We are now confident when we proclaim that the Belimo motor that is made for ecojay and we sell with SmartZone wins in all categories... reliability, noise & installation/setup.

  • EASY pushbutton & dip switch setup makes configuration a snap and confirmation of settings in just a glance – NO manual needed
  • Temperature sensor included & supply temp displayed on the bright led display, visible even in the dark – NO flashlight needed
  • MODES SHOWN ON DISPLAY tell you what the board is doing at all times in plain english – NO guessing what codes mean
  • SmartZone can be used with any equipment – Heat Pump, Gas, Electric, radiant, geothermal, etc. as long as it is controlled by 24v.
  • Single-stage & Multi-Stage equipment can be used (3 heat & 2 cooling stages)
  • Heat pump equipment can be used with auxiliary & emergency heat – both electric and dual fuel -  flawlessly with SmartZone (requires heat pump thermostat connected to Zone 1)
  • SmartZone can be paired with any thermostat from the most expensive WiFi stat to the cheapest mechanical thermostat.
  • Any 24v damper (Spring or power) can be controlled by SmartZone
  • Smartzone has exclusive advanced features:
    •     - Economy Mode allows setback of all zones with the     flip of a switch.  When in eco mode, the system will only     energize if zone 1 makes a call.  This feature is great for vacations or if some of the zones are rarely used.
    •     - Fresh air control allows control of an outside air damper and the system fan on a schedule to bring in fresh air in a prescribed amount.  If fresh air control is required, smartzone-4x has it covered with no additional controls required.  Save $
    • - Smartlink: expand to 20 zones by simply connecting multiple 4X boards together with the smartlink bus. Easiest & most cost effective system for more than 5 zones!
  • Smart staging & limit protection – by using a sophisticated time and temperature algorithm perfected over decades of programming, smartzone stages up and down in the most effective and efficient manner possible.
  • 2nd stage lockout – by setting this dip switch, smartzone will only allow 2nd stage if more than one zone is calling
  • Stage from zone 1 thermostat – allows for a multi-stage thermostat to be connected to zone 1 and control zoning instead of SmartZone (not recommended in typical circumstances)

Damper Wiring: Yet another 5-terminal damper style wired to SmartZone

Supportzoning supply1 Comment

We confirmed today, thanks to a helpful customer, how another DuroZone damper wires using 3 wires (even though it has 5 terminals).

If your damper motors look like the one shown, wire to SmartZone as shown.

Another DuroZone model… on this model it is reported that some versions TERMINAL 4 (the blue wire shown) goes to CLOSE instead of OPEN.

If your motors looks different than this, see our other posts about damper wiring:
4-Terminal and 8-Terminal Damper Wiring

If the motors you have are not compatible with SmartZone, you still don't have to replace the whole damper.  You can replace just the motor (actuator) on just about any standard residential damper with the SmartZone / Belimo motor.

Retro thermostat... 1982 Electronics Guide review of Magic-Stat

Other HVACzoning supply1 Comment
magic-stat.jpg

Published in Playboy's Electronic Entertainment guide in Fall 1982. 

This is off of our normal subject but I came across this old magazine that includes other articles like "There's more to life than Pac-Man: How to beat Donkey Kong" and "What computers can do for you" which says that "VisiCalc is the most popular program of all time with 250,000 copies sold".  And it included a scathing review of this Magic-Stat product.  Sold for $79 mail order.  At first glance, I thought it was just another ugly thermostats in a long history that still goes on today.  Then i read the article which explains a "LEARN" mode that makes it easier to set much like the nest would do decades later.  Also, it claims to have what is now reffered to as "adaptive recovery".  This is where the thermostat starts the equipment before the set time so it can get the home to temperature at a specified time instead of just starting to get to temperature at the time of setpoint.  I haven't done any fact-checking, but it says they are the first thermostat to do this... too bad it took 20 years for this to become a more standard feature.

Here are a few more pics I took of the magazine...i claim no rights or ownership of any of this material.

SmartZone - The only zone control you'll need

zoning supplyComment

The only Zone Control you will need!  Over ten years to perfect the latest version of SmartZone design.  Attention to detail during engineering SmartZone make it the ultimate combination of simplicity, features & compatibility.  Contractors install our board every day with confidence and you can too.  Most contractors that use SmartZone one time, never want to use anything else again on HVAC zoning applications because it is so easy to install and use.

Zoning System Troubleshooting

Supportzoning supplyComment

Because a zone control system interacts with so many different parts (thermostats, transformers, heating/cooling equipment, dampers & temperature sensor), a zoning system can be daunting to troubleshoot when there is a problem.  However, we have realized that there are really just a few common issues are the cause most all of the issues. With a combined 20+ years of zoning questions and technical support calls, we have tried here to boil down to the top 5 reason 99% of zoning systems have a problem.  These do not include a potential problem with the configuration of the Zone Control itself.  The troubleshooting of the zone control configuration is covered well in most Installation Guides.

1. Equipment
   Refrigerant charge, fan speed, wiring, power, etc.
   Always verify that the equipment is working properly first!
2. Thermostats
  a. Incompatible with zone panel
  b. Defective thermostat
  c. Wiring defect
3. Zone Dampers
  a. Actuator failure
  b. Mechanical failure
  c. DUCT Sizing (not enough or too much CFM)
  d. Wiring defect
4. Bypass/Relief
  a. Actuator failure
  b. Sensor (Static Pressure sensor defect)
  c. Mechanical failure
  d. Setup (Modulating calibration or weight arm setting)
  e. Orientation of installation (SPC or barometric bypass)
  f. Improper sizing (not enough CFM capacity)
  g. Wiring defect
5. Power
  a. Transformer fuse
  b. Wiring defect
  c. Primary circuit problem (shared/capacity, breaker)
  d. Improperly sized transformer (not enough VA)

HVAC Zoning Bypass Explanation Animation

zoning supplyComment

This simple animation shows as the dampers close to each zone, one at a time, the bypass should gradually open until... when only one zone is left open, the bypass is open all the way.  Airflow can be seen going back through the system to relieve the pressure in the duct.  The purpose of bypass (pressure relief) is to minimize air noise at the register (air vent in the home) and to prevent over pressuring the duct system which can have many negative implications including not enough airflow.

There are many different models of 24VAC dampers available on the market.  Some have 2-wires, some have 3 wires, some have 5 wires and some even have 8 wire terminals.  Nearly all of these can be used with the SmartZone products (2L, 2X & 4X).  Both 2 and 3 wire dampers are straight-forward to wire and even shown in the installation guide that comes with SmartZone.  However, some of the less common types of dampers (4, 5, 6 & 8 wire) require a little more understanding.  How to wire some of them are shown below.

If you have any other type of damper, please contact us and we will help you.

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

Supportzoning supplyComment

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.

Zoned climate control in your car… why not your home?

Zone Control Infozoning supplyComment
dual climate control

For many years, lots of car manufacturers have been putting separate passenger/driver/rear climate controls in cars.  In such a small space, this could be seen a “silly” feature because the passenger & driver are in very close quarters.  In most homes, however, heating and air conditioning systems still tend to have only ONE climate zone (one thermostat).  Dual or multiple climate zones for a home makes much more since than in a car but is not nearly as often implemented.  With SmartZone most existing heating & air conditioning equipment can be upgraded to have multiple climate controls (thermostats) in different areas.  You could have a thermostat in the kitchen, bedroom and living room… comfort everywhere.  Additionally, with SmartZone, areas that are not being used can be turned OFF to save energy.  All the parts you need shipped for free from ZoningSupply.com Zoning experts standing by to answer any questions you have or help with system design.

Why a temperature sensor is so important with Zoning

Supportzoning supplyComment

Equipment Protection

Protecting the equipment from running too hot or too cold is very important consideration when selecting zoning panel.  By the nature of zoning, airflows in the duct work are being adjusted as zones open and close. Even in Pressure Relief is adequately designed using a bypass or other method, temperatures across the coil and the furnace can fluctuate.  An example is on a mild 60 degree day, a single small zone calls for heat.  In this case, a large percentage of already “heated” air is being re-circulated or forced back through the furnace to be “re-heated.”  This condition can cause temperatures that will cause the fail-safe temperature sensor to trip on the equipment.  The same thing can happen in the cooling mode with consequences that look like frozen coils and potentially damaged compressors.

The need for protection has OFTEN been overlooked with zoning and has caused many failures that have been generically blamed on “zoning.” Much of the negative feelings about zoning has been caused by this problem.  The solution is available on most modern panels:  A supply air temperature sensor (discharge air) that allows the zoning panel to cut off the equipment when the temperature is too high or too low.

Staging

The zoning panel used here is determined by the equipment being used on the application.  If the equipment is single stage,  any zoning panel available should work that meets the other guidelines described here.  When multiple stages are being used, there are many less options.  First of all, many inexpensive zoning panels do not control more than one stage (although most of these don’t meet other criteria described in this book either).  Secondly, and often overlooked is the staging control method.  Many available boards simply control second or third stage based on time alone.  In other words… if stage one is on for 8 minutes, turn on stage two.  More accurately, some panels include a 2nd stage lockout if only one zone is calling.  Best of all, some panels available use a supply temperature sensor to stage based on both time and temperature.  With a temp sensor controlling stating the most efficient use of equipment can be made, not to mention the protection from freeze or overheating it provides.
