Description
The Honeywell W7212 is a solid-state economizer logic module designed to modulate outdoor and return-air dampers for efficient free cooling in rooftop units and air handling systems. Compatible with COâ‚‚ Demand Control Ventilation (DCV) sensors, Enthalpy sensors, and Dry Bulb temperature sensors, it delivers integrated ventilation and cooling control.
Features:
- Operates from commercial thermostat and DCV sensor to provide a totally integrated control system.
- Mounts on M7215 Motor or ductwork.
- The W7212 is used with Honeywell Series 72 actuators.
- Combines minimum and DCV maximum damper position potentiometers with compressor staging relay.
- Functions with solid state enthalpy or dry bulb changeover control.
- Terminals included for connecting optional S963B1128 Remote Potentiometer for remote minimum damper position control.
- LED indicates when free cooling is available.
- LED indicates when module is in DCV mode.
- LED indicates when exhaust fan contact is closed.
- W7212C with additional “E” enthalpy curve.
