Honeywell W7750B2011 Air Handling Unit Controller

Honeywell W7750B2011 Air Handling Unit Controller.The W7750A, B, C are LonMark® compliant Constant Volume Air Handling Unit Controllers used to control single zone and heat pump air handlers. High side triac switching (B and C only). Freezestat protection for HVAC equipment (B and C only). Analog outputs (C only). Factory configured via EEPROM with critical user parameter default values. Uses LonTalk® network (E-Bus) communications protocol. High-speed 78 kilobit communications network. Conforms with Echelon® LonMark® HVAC Interoperability standard for Roof Top Unit controllers (profile number 8030). Free Topology Transceiver (FTT) network technology is insensitive to polarity, simplifying installation. Capable of stand-alone operation and has enhanced features available when using the E-Bus network communications. Designed for both staged heating/cooling control and modulating heating/cooling control. Uses either Series 60 Floating Control or PWM (W7750B only) providing modulating control for heating/cooling equipment. Supports two types of economizer control: modulating control and enable/disable control. Provides Proportional Integral Derivative (PID) temperature control. Uses an adaptive algorithm (patent pending) that continuously adjusts the discharge air setpoint as needed (W7750B only). Motion sensor interface for enhanced energy savings. Window sensor input for additional energy savings.
