Zone Control 369
The Zone Control 369 is designed to control the temperature in up to six heating zones using Room Temperature Units (RTUs) or
indoor sensors. The 369 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 control's adjustments and to monitor
zone running times, outdoor high and low temperatures, minimum zone temperatures, and many other useful items.
Additional features include:
• Control Schedule
• Individual Zone Schedules
• Optimum Start / Stop
• Cooling Control or Cooling Enable
• Manual Override

    In order for Zone Control synchronization to work properly, the cycle length on each Zone Control must be equal. Note: If a Zone Control 367/ 368 or House Control 370 / 371 is used with a Zone Control 369, the HEAT CYC adjustment in the 369 should be set to 15 minutes.
  • Page 6 The 369 can provide indoor temperature feedback to a tekmar Reset Control. When multiple Zone Controls are used, each zone control uses its Zo Out output to sequentially pass the information to the tekmar Reset Control. The ZO OUT item displayed in the view menu represents the target from the zone with the highest heat requirement.

  • Page 7: Section B: Cooling

    Section B1: General Cooling GENERAL COOLING The Zone Control 369 is capable of operating a single cooling group to provide either cooling enable (ENBL) Adjust or cooling control (CTRL). This is an adjustable item through the COOL MOD setting in the Control Adjust menu of the control.
  • Page 8 - 01/09 HEAT / COOL CHANGEOVER The changeover between heating and cooling is based on whether or not a display RTU is connected to zone 6 ( tN1 6 ). If a display RTU is connected to zone 6 ( tN1 6 ), the changeover between heating and cooling is selected at RTU 6. A pointer in the lower right hand display of the RTU indicates that this RTU is the designated heat / cool RTU.
