Honeywell W7100C1018 Microprocessor Discharge Air Temperature Controller

The W7100C1018 is a Honeywell discharge air temperature controller, designed for HVAC systems with 2 stages of heating and 4 stages of cooling, operating on 20–30 VAC. It maintains average discharge air temperature in variable air volume (VAV) systems by modulating economizers and sequencing mechanical heating/cooling stages.
