  • The ZC2S two zone HVAC Control Unit allows 2 standard electronic thermostats to connect to a single heating and cooling HVAC mechanical system. It provides two independent "zones" of temperature control by controlling the mechanical system and motorized dampers in each zone. The ZC2S is for use with any residential style standard gas or electric heating HVAC system up to 5 ton capacity. The control unit supports one stage heating and one stage cooling systems. The two zones are truly independent and can be in either heating or cooling modes. The control unit features
    auto changeover from heating to cooling modes and gives heating calls priority. The ZC2S operation is fully automatic and transparent to the user. Each zone thermostat provides the complete and independent control for that zone. You can think of each zone as having a separate heating/cooling system with its own thermostat.

    The ZC2S works with most ELECTRONIC thermostats (Honeywell, White Rogers, Lux). Use only thermostats that are either battery operated or that use both sides of the 24VAC power (they have R and C terminals) from the HVAC system

    Works great! Review by Luke
    Works great!

    Works like a charm. Bought the Suncourt normally open dampers and this controller opens and closes them as expected. Couldn't be happier.

    Works fine. At first I had the two 24 Vac lines reversed to one of the thermostats. The stat looked to be working, but system wouldn't respond to it. Correcting that minor wiring problem made everything OK.

    Replaced a 25-year-old zone controller with this unit. Works great; drives my new honeywell motorized dampers, & interfaces with my ancient honeywell electronic thermostats.

    Actually, I didn't need it. Found a loose connection on original unit. However, the return process was flawless, and the customer service excellent. Received a refund promptly, no hassle. Smarthome gets an A+++ Thanks!

    Thanks to Zeeway for his review and note on the extra +24 wire between controller and furnace. Thing works like a champ. Just put it ahead of your old tstat and let the factory controller worry about the firebox cut off. A zone controller isn't meant to be a direct replacement for your furnace controller. Only been a few days and already seeing the difference in my home. A+

    This unit does not have a thermistor controlled shutoff to prevent firebox overheating. Zones systems by nature cut the CFM and can cause the FAU to shut down requiring a service call reset. The Honeywell HZ311 TruZone controller is comparably priced ($142), handles 3 zones, ganged servo dampers on each with 1-45VA transformer, and has connections for normally open and normally closed. It is and extremely well designed professional unit and worked much better for our application. I highly recommend it over this product.
