Operating the Control
The ZG 215VN can be used at choice for the control of an
air-handling system’s constant discharge temperature (left-
hand system diagram) or a floor heating’s constant flow tempe-
rature (right-hand system diagram).
TheVF/LF temperature sensors monitor constantly the actual va-
lues and transmit these values to theZG control unit. Should the “
temperature or the supply temperature deviate from the target va-
lue, the controller commands the VM servo motor to adjust the
ZR/DR mixing valve.
The mixing valve performs the necessary change to the mixing ra-
tio between the heated supply water and the heating circuit’s retur-
ning cooled water.
TheTW temperature selector is used as remote control. By means
of the P2 selector knob the flow or supply temperature can be mo -
dified. The temperature selector is not absolutely necessary in
functional terms, but it makes the operation easier.
The FT frost protection thermostat (air-handling system only)
works independently from the control unit and protects the air hea-
ter against freezing.

auto Recommended setting for higher energy saving:
automatic change between day and reduced mode
according to the timer with night switch-off.
Only night mode, timer not active.
Constant reduced mode according to the settings on
the setting knobs Bminus C, the timer remains
inactive.

only red LED lights up:
”hotter“
– mixing valve opens
only green LED lights up:
”colder“
– mixing valve closes

nSet the operating mode selector Sto auto
The remaining basic factory settings are printed under 3on the
control unit.
Timer for reduced mode 6
With the aid of the timer, the room temperature during idle periods
can be reduced automatically to save on operating costs.
The timer has a built-in power reserve of approx. 60 hours thanks
to a rechargeable battery.
Changing the program
Factory settings: red pin 6:00, blue pin 22:00.
nPull out the trip pin and insert it again at the desired
switch-on time. Push in the trip pins until they reach the
stop!
Owing to the different lengths, the trip pins must always be inser-
ted in a red/blue alternate ordere. Thered trip pin switches on day
mode, while the blue pin activates reduced mode.
In order to make sure that the rooms are heated well in the morning,
the heating system’s day mode should be activated between a half
an hour and an hour before using the rooms.
Energy saving tip: Reduced mode can be activated up
to an hour before the room is left. The storage capaci-
ty of the heating system and building is enough to
keep the rooms warm for some time.
Timer with day program
The day program is repeated every 24
hours. If a (second) decrease in tempera-
ture is desired in the course of the day to
save energy, the program needs to be ex-
tended. Take the extra trip pins 4and
insert them at the desired time.

Example:
Desired time program
Normal temperature: 6:00 h to 8:00 h and 16:00 h to 22:00 h
Night decrease: 22:00 h to 6:00 h
Day decrease: 8:00 h to 16:00 h
Position of the trip pins
red pin 6:00 h – Start day mode (normal temperature)
blue pin 8:00 h – Start day decrease
red pin 16:00 h – Start day mode (normal temperature)
blue pin 22:00 h – Start night decrease
Timer with week program
The timer has a changeable dial.
With the week program, dialling a different heating program for
each weekday is possible.
The dial is prepared ex factory for the day program and, if required,
it can be changed to week program (see installation instructions).
Setting the right time
To set the time, the time dial is to be placed on the trip pins and
turned clockwise until the indication on the setting marker 7
matches with the current time.
