Standard Product Features

  • Outdoor reset
  • 3 reset slopes - 2 summer, 1 winter
  • Condensing and non-condensing priority set-point
  • Optimum stop setback, optimum start boost
  • Post-cycle pump purge based on run time percent with max limit (boost to 100%)
  • Acceleration boiler, boiler pump, and system pump modulation outputs
  • Sequential/parallel/optimized modulation
  • Low fire hold with respect to load and occupied space temperatures
  • DHW priority, DHW supply set-point, DHW priority override
  • Event scheduling for occupancy used for start and stop
  • External system enable contact, external system reset analog input
  • Calculates real-time load, displays real-time load calculation, and modulates based on real-time load (not supply temperature)
  • Knows boiler max and min BTU outputs and selects/utilizes accordingly
  • Intelligent load selection - chooses boilers based on their relationship to the load for operation
  • Intelligent shutdown uses load, size, type, priority, hours of operation for shutdown of boilers
  • Chooses boilers based on priority for condensing or non-condensing (hybrid)
  • Intelligent load sharing
  • Measures supply return and system flow to determine real-time load
  • Condensing protection program insures non-condensing boilers see minimum water temperatures > 130F
  • System pump rotation lead/lag
  • 3-way valve control
  • All points alarm
  • Minimum modulation signal during run cycle
  • Internal load predictions based on outdoor air, redundancy factor and history
  • Available website hosted on Administrator with full system interaction
  • Uses boiler manufacturer's unique product data in Acceleration Control Algorithm for modulation tuning
  • Minimum stage delay at any percentage of boiler output
