This function is only active in conjunction with an "RC" (room 
controller) function. The set value acts as a filter between the 
setpoint jump (change of the room setpoint temperature setting) 
and the room setpoint at the controller output. The ramp functions 
as an artificial down time on the control path and slows 
heating/cooling. Configuration of the actual control path is 
dependent on this. 

In historic buildings (churches, galleries), it is important that 
heating up and cooling down are damped via a room setpoint 
value ramp so that masonry and artwork are not damaged. 

The function starts with the switching times switch-on/switch-off 
point and the control mode change. 

This function helps prevent jumps in temperature. For this reason: 

•  The ramp is recalculated starting from the actual room 

temperature after a power failure. A setpoint jump does not 
occur. 

•  If a new setpoint jump (setpoint increased, lowering initiated) 

occurs before the room setpoint temperature is reached, the 
new ramp is recalculated starting with the current actual room 
temperature. 

•  An activated ramp takes affect in all control modes. 

This parameter supplements the summer switch-off function. It 
deactivates the respective heating circuit as soon as the 
computed flow temperature setpoint approaches the current room 
temperature setpoint. 

The heating limit parameter can be activated separately for each 
heating circuit. 

 

Switch-off: Flow setpoint < (current room setpoint + heating limit 
setting)
