• No adaption (range ):
At attenuated outside temperatures above 12 °C, the heating curve will not be
adapted.
Example using a nominal room temperature setpoint of 20 °C.

4.47 Locking signal gain
Matching the system to different types of boilers and plant conditions.
The locking signal gain is a final adjustment of the locking signal which leads to a
restriction of the mixing valve. It is the result of a number of integrals such as shifting
d.h.w. priority.
Setting range Unit Factory setting
0...200 % 100
The gain is adjustable between 0 % and 200 %. The setting changes the response of
the mixing heating circuits to restrictions imposed by locking signals, but not that of the
other consumers. Also refer to "mixing valve restriction" in Index.
Setting Response
0 % Locking signal will be ignored
1...99 % Locking signal will be considered as a reduced
signal
100 % Locking signal will be adopted unchanged
101...200 % Locking signal will be considered up to twice the
normal signal
