Setting range 0 to 15
Mixer active zone/dead zone
Note
This setting is only used if parameter set " 1 " (free parameters) has been
selected under " Mixer parameters ".
The dead zone
C
determines the fluctuation range around the set flow tem-
perature in which the mixer does not react (is at zero volts).
As soon as the flow temperature leaves this zone (above or below) the mixer
motor starts to cycle with a certain pulse modulation (mixer active zone,
B
and
D
).
Outside the active zone, the mixer will be permanently closed
A
(above the
active zone) or open
E
(below the active zone).
