GENERAL 
The LYNX controllers CLLYUL1012S, CLLYUL4024S, 
CLLYUL6438S, CLLYVL0000AS, CLLYVL4022AS, 
CLLYVL4024NS, CLLYVL6436AS, and CLLYVL6438NS are 
part of the LYNX family. They are Free Topology Transceiver 
(FTT) L
ONMARK®-compliant devices designed to control 
HVAC equipment. 
LYNX controllers provide many options and advanced system 
features that allow state-of-the-art commercial building 
control. Each LYNX controller is programmable and con-
figurable through software. 
LYNX controllers are designed for use in VAV (Variable Air 
Volume) and Unitary HVAC control applications. Each con-
troller contains a host microcontroller to run the main HVAC 
application and a second microcontroller for L
ONWORKS® 
network communications. Each controller has flexible, uni-
versal inputs for external sensors, digital inputs, and a mix of 
analog and digital triac outputs (see Table 1). The accom-
panying image is of the model CLLYVL6436AS, which 
includes an actuator.

*One Universal Input (UI-1) is user-selectable as a fast digital pulse meter. 
All eight LYNX controllers communicate via the 78 kbps Echelon® L
ONWORKS® Network, using the FTT-10A LONWORKS® 
interface, and are L
ONMARK®-compliant. 
The LYNX controllers are field-mountable to either a panel or a DIN rail.
