Honeywell CLLYVB6436AS LYNX Series VAV Variable Air Volume Controller

I. Basic Positioning
Brand: Honeywell Honeywell CentraLine (Building Automation LYNX product line)
Model: CLLYVB6436AS
Type: Integrated VAV Variable Air Volume terminal controller, with a built-in 5Nm floating vane actuator, specifically designed for commercial air conditioning variable air volume cabinets, BACnet MS/TP building bus programmable controller Honeywell
Comparable on the same platform: Spyder PVB6436AS (Honeywell’s premium series), CLLY is a CentraLine distribution model, the hardware IO and functions are completely the same

IO Channel Configuration (Standard 6/4/3/6 Specifications) Table
Channel Type Quantity Usage Description
UI General Input 6 channels General collection of temperature, humidity, room panel, and differential pressure sensors
DI Digital Input 4 channels Indoor fan status, filter differential pressure, door magnet, fault passive contacts
AO Analog Output 3 channels Heating section, cooling section, variable frequency fan, 0–10V regulation
