Then close the unneeded ducts when a zone calls for heat?** A: SmartZone controllers will open all zone dampers when there are no zone thermostats calling for heat, cool or fan only operation. When a call is made from any zone and there are no calls active from any other zone, SmartZone will close the non-calling zone dampers and the calling zone's dampers will remain open. **Q: is it compatable with carrier infinity units** A: Carrier Infinity is available in several model levels. If your model is using conventional 24VAC controls and thermostats then our SmartZone controls will be compatible. If your Infinity uses Carrier Infinity proprietary "communicating" controls then you will only be able to use Carrier's zoning control product for Infinity systems. **Q: How doe this link to other zones wireless T-stats if the primary is wired?** A: Each wireless thermostat will typically have a separate receiver component that is located at or near the zone controller. The receiver and thermostat are wirelessly linked to each other. The receiver is wired to the zone controller thermostat terminals and relays the wireless signals from the thermostat to the controller. With SmartZone, any wireless and/or wired thermostat can control the equipment. There is no primary thermostat with SmartZone controls unless you configure it to operate that way using our proprietary ECO mode feature. **Q: Can you set the number of devices calling before it operates the system?** A: Any single zone is able to run the hvac equipment by itself or in tandem with multiple zones calling for the same mode. We do not have a setting that allows the user to set the # of zones that must be calling for the same mode before the hvac equipment is energized. Our SmartZone controllers have an "ECO" mode feature that limits all zones except zone 1 from energizing the equipment. The other zones can make thermostat calls and when the equipment is energized they will be able to open their damper and participate in equipment call. The ECO feature is designed to reduce hvac equipment energy usage when the home or building is unoccupied. - Zoning Supply ## Frequently Bought Together - SmartZone-4X Control - 4 zone controller KIT w/Temp sensor - Universal Replacement for honeywell zoning panel truezone hz432 & more - Elk TRG2440 24VAC, 40 VA AC Transformer with PTC Fuse - Zone Damper 8" Round Professional-Grade (HVAC Zoning) - Preminum replacement for Honeywell, EWC, Durozone, more (08) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/339216444-smartzone-4x-smart-zone-control-4-zone-controller-kit-w](https://www.desertcart.co.uk/products/339216444-smartzone-4x-smart-zone-control-4-zone-controller-kit-w) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-23*
