High settings lead to a quicker adjustment of the control deviation, 
while they reduce the stability of the control circuit and can lead 
with excessively high setpoints to the oscillating of the control 
variable (room temperature). 

 

With this setting the heating circuit concerned can be controlled 
through a room controller. This requires a wall device SDW 30 
with room control function. The room controller directly determines 
the required flow setpoint and transmits this information to the 
central device. 

With this setting the control of the respective heating circuit is 
completely room-guided. Weather condition control is inactive. 
However, the parameters for weather response ("heating curve" 
setting) can still be entered. 

 

The switch-on optimisation leads to the set day setpoint being 
reached at the beginning of the set time period of the heating 
cycle, e.g. 6 a.m. to 10 p.m., at 6 a.m. Without switch-on 
optimisation, the heat generator would not be started until 6 a.m. 
The desired day setpoint is not reached until some time later. 

Switch-on time optimisation can occur either with or without a 
room sensor.
