The Zipset System (ZS) is the flagship product of The Zip Group, LLC, (ZG) and is the ultimate answer for adjusting inaccessible air balancing dampers from a remote location. The ZS does away with the long outdated 100% mechanical gadgets in favor of a “one size fits all” electro–mechanical and software solution.
Reliability, economy, aesthetics. The ZS eliminates the need for access doors as well as custom–fitted, labor intensive and often cantankerous twist or sliding cable hardware, (think bicycle brake cables). Gone are worm gears, universal joints, square or round steel rods, or any mechanical gadgets previously associated with adjusting inaccessible balancing dampers.
The Zipset System has been designed to address several issues . . .
- It had to be mechanically as simple and reliable as possible, using 21st Century technology. No access doors, and no “50’s era” worm gears or twist or sliding cable gadgets were even considered.
- It had to be inexpensive to manufacture. Everyone wants quality at a competitive price.
- It had to install easily regardless of job site conditions, without any custom fitting of its parts.
- The features have to make real–world sense. For instance, only the CFM reading at the air device matters. Reading out or ‘dialing in’ the blade angle position during the balancing task adds cost but has little or no value.
- To minimize field installation labor costs, the ‘average time to install’ of 5 to 10 minutes had to be a realistic goal. There would be no need for any special framing or misc. hardware to support the ceiling receptacle.
- The system had to accommodate ducts designs where control of the dampers might be required at distances of 100 feet or more.
- A method of verifying the integrity of the electrical and mechanical connections prior to the ceiling installation had to be included.
- Adjustment of the balancing dampers had to be an efficient and precise task. To save time and labor expense, a single balancing technician could take downstream air flow measurements while simultaneously adjusting the damper with wireless remote control.
No. The very flexible two conductor power-signal cable from the actuator to the connection point (ceiling brackets or remote panels) can be routed freely as needed around any above-ceiling ductwork, piping, conduit, cable trays, etc. The 8 ft cable which comes pre-wired on every ZSA-1 actuator, as well as extension cables when needed, are plenum-rated (CMP) for use above ceilings designed for return air flow to the AHU.
No. The handheld controllers, HHC-1 and HHC-1R, standard 9 volt battery provide all the power required to operate its electronics as well as the ZSA-1 damper actuator.
Usually. The ZS offers a very competitive line of commercial-grade, galvanized balancing dampers, which generally ship with the ZSA-1 actuator preinstalled, ready for mounting to the ductwork. Customer feedback has confirmed that this is the most economical way for a contractor to provide the damper requirement, when the labor cost for mounting the actuators is included. Click on the damper image near the bottom of the home page for details.
No problem. The unique design of the ZSA-1 actuator allows it to be easily installed on almost any round, oval or rectangular dampers using the included universal mounting bracket. All that is required is for the damper blade drive shaft to be from 1/4″ thru 1/2″ round, hex or square profile, and have a free extended length of at least 3-1/4″. Refer to the ZSA-1 actuator details by clicking its image on the home page.
The ZS standard round dampers range from 4 thru 20 inches. The ZSA-1 actuator torque is rated at 30 in-lbs, which is sufficient to operate free moving rectangular dampers up to 12 sq ft at 2″ max w.g. The maximum single blade damper size is 24W x 18H. However, up to three sections can be ganged together in the width dimension when 24 inches is not wide enough. Only one actuator is required to operate this arrangement.
The design of the ZSA-1 gear train is such that once the balancing is completed at a particular air device, and the power from the HHC controller is disconnected, the actuator permanently locks the damper blade in position.
The CR-1 bracket is usually a good choice when the connection point to the actuator power cable will be in a hard ceiling and generally within a few feet of the actuator. On the Home Page, click on the ‘Option #1’ image for more details.
Yes. The standard configurations are 4, 8, and 12 connector panels in white powder coat finish for mounting in minimum 2-1/2″ deep electrical gang boxes. The ZS also offers panels in any qty of connectors and mounting options. Contact your rep for inquiries and pricing.
The HHC-1R control module works with most current Apple devices including the iPhone 4S or newer, the iPad 4th gen or newer, iPad Mini, iPod Touch 5th gen or newer, and the MacBook series. All that is required is that the Zipset App be downloaded to your device from the iTunes Store. The App Store Icon link is on the Home Page. Of course, like its less talented sibling, the HHC-1, the HHC-1R can be used in local mode with the 4 ft cable connected to set air flow using the red rocker panel switch.
The RP Series remote panels are the answer when complete invisibility for aesthetics or tamper proofing is needed along with the added convenience of having several randomly distributed remote damper power cables terminated at a single location.
The distance is somewhat dependent on the existing wall obstruction where the balancing task is taking place. Field testing and actual project experience has show reliable operation for distances up to about 75 feet. A newer model which will be available later in 2014, will double the range to at least 150 ft.
There are two indications that the damper is responding to the commands by the balancing tech. First, when the ZS app is booted up, it will show two indicator ‘lights’ (colored circles) at the top of the screen. The instant the Apple device and the HHC-1R controller are ‘paired’ to each other, the green circle will glow. If either arrow is touched and the damper begins moving as it should, the green indicator will start blinking and will do so until the arrow is released. The second obvious indication will be a noticable change in the air flow reading after a few seconds. In the event the damper is not moving for whatever reason (shorted or open actuator cable) the green light will not blink but rather the steady red circle light will glow.
No. Bluetooth technology only allows one device at a time to ‘lock on’ for control. The instant the BT ‘chip’ in the HHC-1R is activated (by momentarily touching the red rocker switch) it will ‘sweep’ the local area looking for a compatible device, which is any that has the ZS app booted. Once ‘discovered’, usually within a second or two, the green circle will glow, and will then exclude any other BT devices. Unpairing the devices is easily done by simply pressing the home button to close the ZS app. The BT chip will automatically begin a random sweep looking for a new compatible device with a booted ZS app within its range.
None is needed. On the HHC-1, the only time there is any battery drain is when the rocker switch is pressed to operate the damper actuator. In addition, on the HHC-1R there is an added very low battery drain when the BT circuit is active and locked on to an Apple device. If there is no command between the HHC-1R and the Apple device for a period of 45 minutes, the controller auto shuts off via an internal timer. Reconnecting is just a matter of ‘waking up’ the BT chip by momentarily pressing the rocker switch.
Any standard size alkaline or lithium 9 volt battery will operated either controller. Both have a published shelf life of several years. In real world terms of ‘number of balancing events before replacement’, field experience has shown a range of 20-30 for the alkaline and up to 70 for the lithium version. Keeping a couple of extra fresh batteries handy when on a remote project site is always a good idea.
