Boiler Control 284
The Boiler Control 284 is engineered to manage up to four boilers efficiently, ensuring precise maintenance of a target water temperature. It effectively operates both condensing and non-condensing boilers, accommodating modulating, single-stage, or two-stage configurations. This provides a versatile and cost-effective solution for mixed boiler plants, enhancing system performance. The target water temperature can be regulated based on outdoor temperature reset or a fixed setpoint for various heating applications, including space and process heating. Additionally, the 284 supports additional loads such as domestic hot water and fixed setpoint heating.
Features:
- Outdoor temperature reset and programmable schedules for optimized operation
- Compatible with tekmarNet® 4, enabling control of up to four boilers
- Supports both condensing and non-condensing boiler groups with modulating capabilities
- Communication via BACnet® or Modbus® for seamless integration with Building Automation Systems (BAS)
- Primary pump sequencing ensures efficient boiler operation
- Includes DHW priority and setpoint operation for enhanced functionality
- Controls combustion air dampers for precise regulation
- Offers energy, flow, and pressure monitoring for system optimization
- Equipped with boiler isolation valves for added convenience and safety
Moreover, the addition of tekmarNet® Thermostats or a tN4 Gateway 485 further enhances system performance and enables remote monitoring capabilities, ensuring optimal operation and efficiency.
