By-Pass Sizing Calculator

Often with zoning systems a By-Pass is needed to relieve excess air when only a small zone or number of small zones cannot deliver the required air flow thru the HVAC System. A by-pass is often ducted back into the return air or into non-critical, common conditioned temperature areas such as entry ways, hallways, basements, etc.

Select your Maximum Total System Cubic Feet per Minute (CFM), then enter the CFM of your Smallest Zone to calculate the type of By-Pass Damper you require.

Note: If the By-Pass CFM amount is 30% or less of the Total System CFM, No By-Pass is required.

Internet of Zoning – IoZ – Wi-Fi App Based Zoning System


Introducing IoZ System!

The first app-based combination light switch and thermostat. IoZ System solves the problem of rooms that are too hot or too cold because the thermostat is in the wrong place. Invis-A-Stat is the key to the IoZ System providing room-by-room temperature control without the obstacle of running wires for a separate thermostat. The IoZ System app controls both lighting and temperature and fits in any standard light switch box with a standard rocker switch plate.

Additional system components are the Heat Cool Module (HCM), the Wired Damper Sensor (WDS) & the Zone Control Gateway:

ZCG – The Zone Control Gateway is the central means of communication an our IoZ System app to communicate over the internet no matter where you.

LST – Our new Light Switch Thermostat, or Invis-A-Stat™, is a wireless thermostat and light switch that only requires power.

LST Overview

WDS – The Wired Damper Sensor communicates wirelessly with the components of the IoZ System and send power to each pluggable damper. The WDS is also used for each zone to monitor the damper position, duct temperature, pressure, humidity and later IAQ

WDS Overview

HCM – The Heat Cool Module is used to activate the HVAC System for either heat or cool calls. The HCM also communicates wirelessly with the other components of the IoZ System but must be wired to the HVAC unit for operation.
