Slope-offset curve

Slope and offset

Define the weather-dependent curve by its slope and offset:

▪ Change  the 

slope

  to  differently  increase  or  decrease  the

temperature  of  the  leaving  water  for  different  ambient
temperatures.  For  example,  if  leaving  water  temperature  is  in
general  fine  but  at  low  ambient  temperatures  too  cold,  raise  the
slope  so  that  leaving  water  temperature  is  heated  increasingly
more at decreasingly lower ambient temperatures.

▪ Change  the 

offset

  to  equally  increase  or  decrease  the

temperature  of  the  leaving  water  for  different  ambient
temperatures. For example, if leaving water temperature is always
a bit too cold at different ambient temperatures, shift the offset up
to  equally  increase  the  leaving  water  temperature  for  all  ambient
temperatures.

▪ When  slope  is  changed,  the  new  preferred

temperature  at  X1  is  unequally  higher  than  the
preferred temperature at X2.

▪ When  offset  is  changed,  the  new  preferred

temperature  at  X1  is  equally  higher  as  the  preferred
temperature at X2.

Possible actions on this screen

Select slope or offset.

Increase or decrease the slope/offset.

When slope is selected: set slope and go to offset.

When offset is selected: set offset.

Confirm changes and return to the submenu.

Using weather-dependent curves

Configure weather-dependent curves as following:

To define the setpoint mode

To use the weather-dependent curve, you need to define the correct
setpoint mode:

Go to setpoint mode …

Set the setpoint mode to …

Main zone – Heating
