Step up to IP control with Optimizer Unitary Controller
Take advantage of IP-grade cybersecurity, universal I/Os, and groundbreaking twisted pair T1L technology, so you can transfer HVAC data without disruptive and expensive infrastructure upgrades.
FLEXIBILITY BUILT IN
T1L technology allows upgrade to IP without having to rewire the network. Wireless functionality allows mounting in spaces that may be impractical to reach with signal wiring.
EASY TO INSTALL
Mounting in fuse boxes on DIN rails or walls. Relays which can handle up to 277 VAC and high inrush current (100 A). Streamline the pre-commissioning process with mobile app.
SIMPLE TO SERVICE
Convenient retrofit for prior Honeywell models. Color-coded screw terminals to better identify function and placement can be swapped without disconnecting wires.
Technical resource guide
What is T1L ethernet?
T1L can deliver IP speeds and security with the cost-effective reuse of traditional infrastructure that’s already installed. This technical resource guide is designed to help you navigate the basics of T1L Ethernet and understand the technical concepts that make it possible.
Maximum Performance on a Minimal Budget
Upgrading a decades-old building automation system with Honeywell Optimizer unitary Controllers using T1L Ethernet enables a larger government organization to increase operational performance on a limited budget.
