AION EMS Zeus v16.0.41 fixes a false Self-Test error affecting Heat Pump installations using separate Space Heating and Domestic Hot Water measurements.
When Separate Heating / DHW measurements is enabled, Zeus now correctly accepts complete classified Heating + DHW electrical Power and Energy mappings instead of requiring duplicate whole-unit Power and Energy sensors.
Fixed
Heat Pump Self-Test now recognises separate Heating / DHW measurement configurations.
Whole-unit power_entity is optional when complete Heating + DHW electrical power measurements are configured.
Whole-unit energy_entity is optional when complete Heating + DHW electrical energy measurements are configured.
Classified circuit entities are still checked for availability.
Incomplete circuit mappings continue to be reported by Self-Test.
Also included
Battery-aware Forecast Energy Planning.
Separate Solar Surplus, Battery Charging Demand and Flexible Surplus calculations.
Flexible-load forecast windows based on post-battery surplus.
Finance System Payback with investment, subsidy, maintenance, annual benefit and estimated break-even.

Compatibility
