OPTIONAL PARTS (S Series)

Network Convertor (UTR-YLLA)

For connection between our LONWORKS® system and a LONWORKS® open network for the management of a small to medium-sized BMS and VRF system. By using the UTR-YLLA, the VRF system can be centrally controlled or monitored from a BMS with a LONWORKS® interface. Our interface component allows VRF control systems to be designed by others and if necessary reconfigured at a later date. Dimensions (H x W x D) (mm): 67 x 288 x 211 Weight (g): 1500
