3.2.4 Strategy
In the "Strategy" section, the values for the entire heating system are summarized.
This is especially important for multi-boiler systems (cascades).
Format:
Changing the operating mode
With the HVAC_heat / HVAC_off setting, the operating mode for the consumer is changed
externally via the LON data bus.
Set range: 32 °F to 194 °F (0 °C to 90 °C); in 1-degree intervals
Note:
230 °F (110 °C) is an invalid value (e.g. no temperature sensor connected, sensor defective, etc.).
Note:
230 °F (110 °C) is an invalid value (e.g. no temperature sensor connected, sensor defective, etc.).
