ZTech 4 Zones HVAC Controller (for Standard or Heat Pump Systems)

The ZTech 4 Zones HVAC Controller (for Standard or Heat Pump Systems) allows up to 4 standard electronic thermostats to independently control the temperature in up to 4 "zones" or areas of a building using a single heating and cooling mechanical system. Temperature control is achieved by opening or closing motorized dampers in forced air systems or valves in hydronic systems. The 4 Zone HVAC Controller is compatible with Standard or Heat Pump HVAC systems. For Standard HVAC systems, the controllers work with any residential style single stage heat, single stage cooling systems (for split systems with separate power supplies, an external relay is required). For Heat Pump HVAC systems, the controllers work with any residential style two stage heat, single stage cooling systems. The controllers can work with systems with either changeover with cooling (O) or heating (B) inputs. The four zones are truly independent and can be in any mix of heating or cooling modes. The controllers feature auto changeover from heating to cooling modes and gives Heat calls priority. The operation of the controller is fully automatic and transparent to the user and each zone thermostat provides the complete control for that zone.

• Controls up to 4 zones independently with dedicated thermostats
• Compatible with Standard HVAC systems (single-stage heat, single-stage cooling)
• Supports Heat Pump systems (two-stage heat, single-stage cooling) with O or B changeover
• Compatible with normally open, two-position, spring-return, 24VAC motorized dampers, supporting up to four 2-wire damper connections
• Auto heat/cool changeover switches between heating and cooling modes for optimal room temperature
• Thermal Equalizer circulates air from warm areas to cool areas to distribute heat

Why You Would Use This Product:

The ZTech 4 Zones HVAC Controller is ideal for homes where personalized comfort and energy efficiency are priorities. For example, you can set the living areas to be warm during the day while keeping bedrooms cooler for better sleep. In multi-level homes, the ZC4 allows you to manage varying temperature needs between floors, ensuring comfort and consistency. By minimizing heating or cooling in unoccupied zones, the controller also helps reduce energy waste and cut utility bills. Families with differing climate preferences will especially benefit from the ZC4's ability to independently manage each zone's temperature.
