Tekmar Controls 256 Control
The Tekmar Controls 256 is a sophisticated 24Vac single stage boiler control engineered to optimize hydronic system efficiency through precise outdoor reset technology. Designed for veteran contractors, this microprocessor-based control adjusts the boiler supply temperature based on fluctuating outdoor conditions, effectively preventing short cycling and reducing energy consumption. The unit features a characterized heating curve that allows for fine-tuning based on the specific terminal unit type, whether you are dealing with high-mass radiant floors, baseboard radiation, or fan coils. With its automatic boiler differential and warm weather shut down (WWSD) capabilities, the 256 ensures the heat source operates only when necessary, protecting the heat exchanger from flue gas condensation by maintaining a user-defined minimum supply temperature. The clear LCD display provides real-time system status and simplifies the quick setup sequence, while the setback input allows for seamless integration with night setback schedules for maximum building performance. This reliable one stage boiler control is CSA C US certified and utilizes 10k NTC thermistor sensors for high-accuracy temperature monitoring.
Key Benefits- Outdoor Temperature Reset: Dynamically calculates the boil target temperature to match building heat loss, significantly improving seasonal efficiency.
- Flue Gas Protection: Adjustable minimum boiler temperature settings prevent acidic condensation in cast iron and non-condensing heat exchangers.
- System Versatility: Compatible with multiple terminal unit types, including fin-tube convectors, radiators, and radiant tubing.
- Advanced Differential Logic: Features automatic boiler differential to reduce burner cycling and extend the life of mechanical components.
- Energy Management: Built-in warm weather shut down and night setback inputs for superior energy savings during unoccupied or mild periods.
How do I prevent short cycling with the Tekmar 256?
Utilize the Auto Differential setting or manually widen the boiler differential in the "Adjust" menu to ensure longer, more efficient burner run times, especially in low-mass systems.
Can this control protect against boiler condensation?
Yes. Technicians should configure the BOIL MIN setting (typically to 140°F for standard cast iron units) to ensure the return water temperature does not drop below the dew point of the flue gases.
Is the outdoor sensor required for operation?
While the 256 can provide a setpoint control function, the outdoor sensor is essential to enable the outdoor reset logic and the characterized heating curve for maximum efficiency.
