The derivative action time Tv defines the time a spontaneous change of the control
deviation continues to be felt. A short derivative action times only has a short-time
impact on the manipulated variable

Full charging with B36
No
Yes
Here, you can select whether the end of full charging shall be detected by sensor B36.
No
The end of full charging is detected by sensors B3 and sensor B31 at the top and
bottom of the storage tank.
Yes
The end of full charging is detected by sensor B3 at the top of the storage tank and by
sensor B36.

This parameter determines the rate at which the locking signal increases with shifting
priority. The longer the set time, the more slowly the locking signal increases.
Note!
In general, this parameter is used in connection with the DHW storage tank.

Min start temp diff Q33
This parameter determines the switch-on delay of the intermediate circuit pump
depending on the boiler temperature. The intermediate circuit pump is activated
whenever the boiler temperature reaches the level of DHW setpoint plus the value set
here. When setting this parameter to -5 °C, for instance, the intermediate circuit pump
is activated as soon as the boiler temperature reaches a level 5 °C below the DHW
setpoint. Setting OSV means that the intermediate circuit pump is activated with no
delay.
Line no.

Excess interm circ temp del
Control of the burner output according to the charging temperature is activated when –
since the start of the intermediate circuit pump – the time set here has elapsed.
