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
