Mixed Plant Boiler Stager

The Boiler Control 284 is designed to operate up to four boilers to accurately maintain a target water
temperature. The 284 operates both condensing & non-condensing boilers that are either modulating,
single stage or two stage to provide a flexible, cost effective mixed boiler plant solution with better
performance. The target water temperature is based on outdoor temperature reset or a fixed setpoint for
space or process heating applications. Additional loads supplied by the 284 include domestic hot water &
fixed setpoint heating. Boiler equal run-time rotation, stand-by primary pump operation & pump
all increase boiler plant reliability. The 284 communicates with a Building Automation System (BAS) using
BACnet® or Modbus® for remote monitoring & adjustment capability. tekmarNet® Thermostats or a tN4
Gateway 483 can be added to optimize system performance & provide remote monitoring capability.
