Boiler ManagementA new hybrid control from Heat-Timer Corporation called the Mini-MOD-CNC automatically mixes and matches non-condensing boiler operation and condensing boiler operation to optimize efficiency of a combined system. It also allows for mixed control of modulating and staging boilers, since condensing boilers typically have modulating burners and non-condensing boilers typically have staging or on/off burners. The control automatically switches to high mass boilers when the building heat requirements approach design loads. So high mass boilers operate when they are most efficient (at peak loads) and condensing boilers operate when they are most efficient (at part load).
The 274 and 275 are the newest Tekmar Control Systems Ltd. boiler staging controls for multiple boiler installations. They are the first standalone boiler controls featuring tekmarNet®4 (tN4) Networking technology. Both the 274 and 275 operate up to four boilers using PID staging to maximize system efficiency. The 274 operates on-off boilers while the 275 operates modulating boilers. The controls are also compatible with the Gateway 483 for remote access and monitoring via the internet.
