From the Tekmar Catalog- The Tekmar Controller 369 is designed to control the temperature in up to six heating zones using Room Temperature Units (RTUs) or indoor sensors. The 369 zone control allows one stage heating zones, two stage heating zones, or a combination of one stage and two stage heating zones. PID zoning logic allows for staggering and synchronization of multiple zones in order to minimize boiler short cycling. The 369 is capable of operating a single cooling output and can provide automatic or manual heat / cool change over. When the 369 is used with a tekmar Reset or House Control, the 369 provides indoor temperature feedback that automatically adjusts the supply water temperature in order to satisfy the zone with the highest heat load. A large Liquid Crystal Display (LCD) is incorporated in order to view system status and operating information. The LCD and user key pad are used to set the adjustments and to monitor zone running times, outdoor high and low temperatures, minimum zone temperatures, and many other useful items.
