S3S - Three-Stage Boiler Control Overview The S3S is a Three-Stage Boiler Control which can stage up to three boilers using PID logic for better control of the system temperature. The S3S will enable just enough stages to maintain either a fixed or an outdoor reset set point. The S3S has multiple uses including: Staging three Triangle Tube Boilers to maintain the desired set point for either heating or domestic applications. Staging between multiple sources of heat such as Solar, Geothermal Systems and a Triangle Tube Boiler.
Features •
Stage 3 Triangle Tube Boilers The S3S can be configured to stage up to three Triangle Tube Boilers to maintain the desired system set point.
•
Fixed Lead Stage or Automatic Rotation The S3S can be configured to always start with the same stage or automatically rotate the lead stage to equalize runtimes.
•
Stage 2 Triangle Tube Boilers with a System Pump The S3S can also be configured to stage up to two Triangle Tube Boilers and operate the System Pump.
•
External Enable The S3S can be remotely enabled from an external device or controller.
•
System Pump Run-On The S3S can be configured to provide the System Pump with an additional Run-On time to disburse heat from the boilers.
•
Sensor Fault Operation The S3S provides the option of switching on or off all stages if a sensor fault should occur.
•
Fixed Set Point or Outdoor Reset The S3S can stage up to three boilers to maintain either a fixed set point or operate using the outdoor reset function. The outdoor reset function utilizes fixed reset curves as well as providing the option for custom user defined heating curves.
•
Digital Display Large 2 x 16 character display provides status information as well as easy parameter adjustments in plain English.
•
English or Metric Units The S3S can be configured to operate using either English or Metric units.
•
Mounting Options The S3S can be mounted on a standard 4” x 4” electrical box or can be panel mounted using the included plastic wiring enclosure.
•
Outdoor Cutoff The optional Outdoor Cutoff function can disable the system when the outdoor temperature rises and heat is no longer required.
