7.7.2.5. Increase (default setting is “0”)
If the temperature drops very fast, this value is subtracted from the measured flow temperature
so that the mixer’s reaction is stronger. If the measured temperature does not drop any more,
the measured value is used again. The measurement occurs once every minute.
These settings are only necessary in special cases at the time of initial
commissioning by the specialist. Incorrect measurement values can lead to
unpredictable errors and wrong functioning of the heating system.
7.8. Relay 2 (settings for R2 output)
In the RegulusBIO load unit the mixing valve (closing) is connected to the R2 output.
For this reason keep the R2 setting at 7.8.3.
7.9. Relay 3 (settings for R3 output)
Items 7.9.1. to 7.9.3. are reserved for outputs R1 and R2 in the BIO MIX load unit (do not
assign them to R3 output).
For variant 3 the option “Heat transfer” (7.9.7.) is pre-defined and cannot be changed.
For other variants the options for setting the output R3 are following:
7.9.6. Difference
Difference thermostat settings are described in Chap. 5.5.
7.9.7. Heat transfer
Heat transfer settings are described in Chap. 5.6.
Preset option for Variant 2.
7.9.8. Thermostat
Thermostat settings are described in Chap. 5.7.
7.9.9. Heating element
Heating element settings are described in Chap. 5.8.
7.9.10. Solid fuel boiler
Solid fuel boiler settings are described in Chap. 5.11.
7.9.11. Solar
Solar circuit settings are described in Chap. 5.12.
7.9.12. Gas boiler (Burner)
Gas boiler settings are described in Chap. 5.17.
7.9.14. Return flow increase
Return flow increase settings are described in Chap. 5.22.
7.9.15. Circulation
DHW recirculation settings are described in Chap. 5.23.
7.9.16. Error messages
The relay will close when an error occurs. This function can be reversed, which means that
the relay will be closed normally and open when an error occurs.
The Controller error conditions are:
Collector protection
System protection
Frost Protection
Recooling
Anti Legionella
Message
– a relay is activated when an informative message is displayed.
