The EBC 31 is a multi-use draft or pressure controller with integrated webserver and remote access used with fans and dampers to monitor and maintain a constant draft or pressure by varying the speed of a fan(s) or the position of an actuator. Typical uses are:

• Maintain a constant draft by modulating a power venter in a mechanical draft system serving boilers and water heaters,
• Maintain a constant draft by modulating position of an over-draft damper serving boilers and water heaters,
• Maintain a constant duct pressure in a dryer venting system or a ventilation system
• Control the supply of combustion air to a mechanical room or directly to a boiler(s)
• Control and maintain room pressure

Features

• Controls 3 air plenums (exhaust fan, damper and supply fan) via individual PID loops.
