Io Hvac Controls SC-Z20-NS Night Setback Thermostat

Product Description

The IO HVAC CONTROLS SC-Z20-NS is a night setback thermostat designed to work with the SC-Z20 zoning system. It allows scheduled temperature reduction during unoccupied or overnight periods, helping maintain consistent comfort levels while reducing unnecessary run time. The SC-Z20-NS mounts at the zone level and communicates with the SC-Z20 controller to execute setback schedules without requiring manual adjustment at each zone. HVAC technicians and zoning system installers are the primary trades who work with this component.

The SC-Z20-NS is intended for use in zoned HVAC applications where the SC-Z20 system is already installed. It is suited for light commercial and residential installations where individual zone temperature scheduling is required. Typical deployment involves replacing a standard zone thermostat with this setback-capable unit to gain overnight or unoccupied-period temperature management at that zone.

Key Features

• Night setback functionality allows automatic temperature reduction during scheduled unoccupied periods
• Designed as a direct accessory for the SC-Z20 zoning system
• Compact form factor at 5.5 x 2.5 x 6.75 inches for standard wall installation

Compatibility

Designed for use with the IO HVAC CONTROLS SC-Z20 zoning system as a zone-level night setback thermostat accessory.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage thermostat wiring and zoning control systems. Power down the SC-Z20 zone controller before wiring or removing any thermostat connections. Follow all applicable local codes and the SC-Z20 system documentation for proper zone assignment and setback schedule configuration. Do not apply line voltage to low-voltage thermostat terminals.
