Page 11: Return T Limit (Return Temp. Limitation) 4000
A recommended setting value for ‘Limit’ in DHW systems with constant flow has the same value as the desired DHW temperature. This prevents that the return temperature limitation is activated when idle (no DHW tapping / DHW draw-off). AQ188586469032en-010701 © Danfoss | 2020.12 | 11... -
Page 12: Gain - Max. (Return Temp. Limitation - Max. Influence) 4035

‘Tn’ = 0.85 x critical time period ‘Xp’ = 2.2 x proportional band value in the critical time period. If the regulation seems to be too slow, you can decrease the proportional band value by 10%. AQ188586469032en-010701 © Danfoss | 2020.12 | 17... -
Page 18: Open Time 6094
When a ‘forced opening time’ is chosen in 6094, the setting in 6097 results in the following: The S3 temperature is maintained (assuming that a DHW circulation is OFF: present). The S2 temperature is maintained (assuming that a DHW circulation is not present). 18 | © Danfoss | 2020.12 AQ188586469032en-010701... -

A PI control does the same as a P control, but the offset will disappear over time. A long ‘Intgr. time’ will give a slow but stable control, and a short ‘Intgr. time’ will result in a fast control but with a higher risk of oscillations. AQ188586469032en-010701 © Danfoss | 2020.12 | 35... -
