For nearly three decades, tekmar has been providing zoning and control solutions for a variety of heating and cooling applications. Products made by tekmar can improve the efficiency and comfort delivered by almost any system. Their 284 Boiler Control allows you to manage the operation of up to four boilers to supply an outdoor reset determined temperature. In addition to this system temperature, the 284 will also control the production and delivery of two additional, separate temperatures for domestic hot water production and setpoint applications. This unit provides power and control for two system pumps, an indirect domestic hot water pump, and four boiler pumps. Whether you are using it in a stand-alone capacity or as a part of a tekmarNet control system, the 284 Boiler Control possesses several energy saving and operation features to make you system more economical.
Intelligent Boiler Rotation
The tekmar 284 allows boilers to be assigned to a boiler group depending on their features and efficiency. This control can be set to operate the most efficient boiler groups as the primary source of heat to maximize the efficiency of the system. The 284 will also rotate the boilers within these groups to distribute total operation time and wear on the boilers equally.
By monitoring system and outdoor temperatures, the tekmar 284 is able to make intelligent decisions about system operation. This includes adjusting supply temperatures based on outdoor conditions and providing boiler protection by monitoring and maintaining a minimum return water temperature. With the wide variety of operating modes and equipment it supports, the tekmar 284 is sure to make your system operate more efficiently, without sacrificing comfort.
Synchronize Your Zones, Save Energy
The 284 Boiler Control allows your tekmarNet 4 thermostats to communicate with each other. Communication means that your thermostats can synchronize their cycles, when possible, instead of operating independently. This minimizes short cycling, saves energy, and reduces wear and tear on your system.
Proportional, Integral, Derivative (PID) Staging Mode
In PID mode, an advanced algorithm weighs many variables, including sensor temperatures, when making operation decisions. PID reduces short-cycling, improves efficiency, and prevents temperature drops in your system.
Program Your Ideal Schedule
The tekmar 284 allows you to define time periods when your building is unoccupied and the water temperature may be reduced. This control supports the following setback schedule formats: 24 hours, seven day, weekday/weekend, and Saturday/Sunday/weekday. You may schedule two or four events per day. If you connect the 284 to a tekmarNet system your schedule can be maintained independently, or it can be applied to tekmarNet thermostats as a system-wide master schedule. The 284 can also follow master schedules as set by other devices.
