The IO HVAC CONTROLS SC-Z20 is a 20-zone commercial zone control panel designed to manage multiple independent HVAC zones from a single centralized unit. It coordinates zone dampers, thermostats, and air handlers to deliver conditioned air only where and when it is called for, reducing energy waste across large multi-zone systems. Licensed HVAC technicians install this panel in commercial buildings, multi-tenant properties, and large residential applications where a single air handler serves numerous zones simultaneously. The enclosure measures 11.5 inches wide by 3.5 inches high by 14.5 inches deep and weighs 3.35 pounds.
The SC-Z20 is suited for commercial HVAC installations requiring centralized zone management across up to 20 discrete zones. Typical applications include office buildings, retail spaces, schools, and multi-unit residential buildings where individual zone temperature control is required. The panel interfaces with zone dampers and low-voltage thermostats to sequence zone calls and manage the air handling equipment accordingly. It is installed by licensed commercial HVAC technicians familiar with multi-zone system design and low-voltage control wiring.
Designed as an OEM-style replacement or new-installation zone control panel for commercial multi-zone HVAC systems using low-voltage thermostats and motorized zone dampers.
Installation should be performed by a licensed HVAC technician familiar with low-voltage commercial control wiring and multi-zone system design. Disconnect all power to the air handling unit and zone damper actuators before wiring the control panel. Follow local mechanical and electrical codes, including applicable NEC requirements for low-voltage control circuits. Verify that the total number of active zones does not exceed the panel capacity before commissioning the system.
