Heat sources are assigned a priority, representing the preferred order in which they fire, with 1 being the lead.
Uncontrolled heat sources, such as solar thermal, have a priority of 0. Heat much be taken if available.
Heat sources with the same priority will be run in duty/standby and rotated.
Beat sources are fired up according to store depletion, both on volume remaining and rate of depletion.
Heat sources of lower priority will be exercised.
Modulation will be applied to heat sources where possible to match loads and minimise cycling.
Timing functions can be applied.
Includes functions for override of non-critical loads, such as central heating, when store close to empty.
Includes functions for activation of heat dump circuits for solar thermal and biomass.
Includes functions for boiler loading valve and pump control (with DP switch or sensor).
Includes alarm functions for low/high temperature, low/high pressure, low storage, failure of heat sources.

The following schematic was generated using our open-source Heat Network Designer software.
