MENU > Settings > Return limit
High limit Y2 (return temp. limitation, high limit, Y-axis)
Circuit
All
Set the return temperature limitation referring to the outdoor temperature
value set in 'Low T out X2'.
* See Appendix "Parameter ID overview"
The corresponding X coordinate is set in 'Low T out X2'.
MENU > Settings > Return limit
Infl. - max. (return temp. limitation - max. influence)
Circuit
All
Determines how much the desired flow / duct temperature will be influenced
if the return temperature is higher than the set limit.
* See Appendix "Parameter ID overview"
Influence higher than 0:
The desired flow / duct temperature is increased, when the return
temperature gets higher than the set limit.
Influence lower than 0:
The desired flow / duct temperature is decreased, when the return
temperature gets higher than the set limit.
MENU > Settings > Return limit
Infl. - min. (return temp. limitation - min. influence)
Circuit
All
Determines how much the desired flow / duct temperature will be influenced
if the return temperature is lower than the calculated limit.
* See Appendix "Parameter ID overview"
Influence higher than 0:
The desired flow / duct temperature is increased, when the return
temperature gets below the calculated limit.
Influence lower than 0:
The desired flow / duct temperature is decreased, when the return
temperature gets below the calculated limit.

Example
The return limit is active above 20 °C.
The influence is set to 0.5.
The actual return temperature is 2 degrees too high.
Result:
*
The desired flow / duct temperature is changed by 0.5 x 2 = 1.0 degree.
Example
The return limit is active below 50 °C.
The influence is set to -3.0.
The actual return temperature is 2 degrees too low.
Result:
*
The desired flow / duct temperature is changed by -3.0 x 2 = -6.0
degrees.
Normally, this setting is 0 in district heating systems because a lower
return temperature is acceptable.
Typically, this setting is higher than 0 in boiler systems to avoid a too
low return temperature (see also 'Infl. - max.').
