Functionality
- 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.
