    Honeywell Optimizer Unitary Controller (24V)

    A part of the Honeywell Optimizer Suite, the Honeywell Optimizer Unitary Controller allows you to wire them or connect wirelessly – even take advantage of groundbreaking twisted pair T1L technology

    Overview
    Honeywell Optimizer Unitary Controllers provide flexible, freely programmable, demand-led control that delivers tangible benefits to reduce energy spending while driving new levels of functionality and efficiency in today’s buildings.They offer performance-based engineering with Niagara 4 and enable Single-Tool-Engineering throughout the whole Building Management System with cost-effective installation. These controllers contain integrated Bluetooth for an easy connection to commissioning apps.Features & Benefits:
    • Ideal for fan coils, split systems, unitary vents, air handlers, or other self-contained units
    • Daisy chain ethernet connection ensures reliable data speed over greater distance
    • T1L technology allows you to upgrade to IP without having to rewire your network
    • Connect to the controller via Bluetooth® Low Energy (BLE). Easy pairing, no need to open the ceiling for recalibration
    • Secure communication. Your OT network can be as secure as your IT
    • Mounting in fuse boxes on DIN rails or walls
    • Relays which can handle up to 277 VAC and high inrush current (100 A)
    • Power supply 24 VAC or DC
    • Optional terminal covers and strain relief via cable ties
    • Convenient retrofit for prior Honeywell models
    • Color-coded screw terminals to better identify function and placement can be swapped without disconnecting wires
    Certifications:
    • CE mark
    • UL 916
    • UL/ULC 60730-1
