Hey Cody, I am planning my ERV set up for my upcoming home build. I am trying to sort out the control system for the Zehnder unit. My initial thought is to have the LAN-C and option box set up like you have it here, with a switch in each bathroom, and the primary control interface being the app on my phone. Would it also be smart to run something like the C67 switch or controller so you could have local control of the unit without having to get on the app?
Thanks for asking. Many people like to have the C67 in the kitchen or by another heating/cooling thermostat. Many like the app when they're away from the cabin for example. They can see temps and humidity levels and know exactly what the air is doing inside. Likewise, MainStream can see all our client's units remotely for troubleshooting. That said, many also do not get an extra controller. They use the controller on the face of the Q or the app. Breathe Clean and Easy--Cody
@@PassiveHouseCody Cody, thank you for your response. I have been looking through what you offer on your website. I am leaning toward a Zehnder unit for our build. Wondering if you have many home owners who do the install themselves vs having the HVAC contractor install it. Without running any real numbers, I feel like I could install the Zehnder system myself and come out even with a better unit, than if I had the HVAC contractor install a lesser quality/capable unit.
@@south_coast Great comments and questions. A quick back story: We started green building in 2004, when a mentor told us if we GC our own project we could save 10%-20% right off the bat. From our research, that was also the cost to upgrade buildings to ' Green, NetZero, Passive House.' From that moment on we put the power in the owner's hands with education AND installation support. Owners install these systems best because industry installers haven't caught up yet, cut corners and are budget driven NOT results. Owners are results driven and not happy when it's compromised. MOST installers do not understand Zehnder can't be substituted because of efficiency, horsepower, quietness AND it's the only unit with a built-in pre-heater. The only unit for the rocky mountain climate. Further most subs do not understand precision extraction and delivery, 3" ducting to Manifold. Meaning they're okay diluted fresh air or not using airtight ducting, which is the ComfoTube/ComfoFlex . So yes. You can install it, you do not need a license and you'll do it best! Commissioning will ensure you did it correctly, which Zehnder is the only manufacturer that insists commissioning in order to substantiate the warranty. From design, install support, to QA; you'll get it right because you began with the end in mind.
