SC Modular Heating Plant Control Packages
Optimized Multiple Boiler Sequencing and Auxiliary Heating Equipment Control
|
| Custom designed and
built panels configured for specific applications and buildings deliver
multiple boiler control superior to that provided by currently available
off-the shelf sequencers. Startup plus interstage delays eliminate
control overshoot in response to restart system overhead and temporary
load fluctuations. Use of field replaceable components minimizes repair
expense and downtime over installation life. Standard features include:
• Digital Electronic Sequencing • Outdoor Reset Temperature Control • Individual Firing Position Selector Switches • Adjustable Startup and Interstage Delay Timers
|
• Plug-in Cycling and Firing Rate Stage Relays • Common C.A.D. (with proof) and/or Emergency Shutdown Interlock Digital electronic temperature controls (Indoor/Outdoor Low/High Limit, Startup Boost, System Alarm), 7-Day Programming, pump (system circulating or boiler feed) interlock, and PLC-based deadband control with status report and network capability are among available options |
| Partial Load Efficiency: Modular heating plants achieve high partial load efficiencies by matching individual modules to light loads. With true parallel primary/secondary piping and correct control including warm weather and night/weekend shutdown, light load equipment cycling is minimized while both unnecessary heating plant operation and excess capacity heat loss paths are completely eliminated. |
