The TLEE Expansion module greatly expands the capabilities of NCD Fusion series controllers. The TLEE module includes a Real-Time clock, Battery Backup Circuit, and a EEPROM chip. The TLEE module enables the Taralist (Time Activated Relay) Feature set for Fusion Series controllers. In addition, the on-board EEPROM memory is used to enable about 60% more Reactor features (for use in Sensor Controlled Relay applications). The TLEE includes a mounting screw and may be added to Fusion controllers after purchase. Simply install and power-up Fusion. Run our Base Station software to unlock the extra Fusion control panels.
