Optimization of the Settings
The ZG 215VN control unit is a constant temperature controller.
The desired temperature, e. g. the supply temperature of an
air-handling system or the flow temperature of a heating system
can be set on the setting knobs
B
and
C
of the controller.
Day mode (setting knob
B
)
The selecting range on the setting knob
B
varies from 0 to 100°C.
Normally the setting knob
B
sets the desired target value for day
mode.
If a temperature selector is used as a
remote control, the setting knob
B
is to be
set on 20.
Reduced mode (setting knob
C
)
By means of setting knob
C
, the intensity of the decrease to be ac-
tivated with the timer can be set. The setting range varies from 0 to
-100 K (°C). The decrease set with setting knob
C
refers to the
temperature either on setting knob
B
or on the TW.
