Ventilator control

With the temperature
feeler, inserted in
Prophi, and a ventila-
tor, a simple ventilator
control can be estab-
lished.
Therefore, an
upper temperature limit, a
lower temperature limit and a

switching output

must be fixed.
Please note, that the inner temperature of the Prophi is
about 2°C over the outer temperature.
A relay output or the alarm output (option) serves as
ventilator output.
If the switching output 0 is assigned to the ventilator
control, the ventilator control is not active.
An upper and lower temperature limit can be set. The
temperature limits can be set in the range of 0°C and
98°C in 1° steps. While programming, you can only set
an upper limit, when it is at least 1°C over the lower
limit.
Attention! If an output is programmed for ventilator
control, and if it is also programmed for a fix stage or
alarm output, the ventilator control has higher priority.

Ventilation control

Using the temperature
sensor, which is in-
serted within Prophi, a
simple ventilation con-
trol can be built.
To reach this goal, an
Upper temperature limit, a
Lower temperature limit and
A switching output
must be determined.
While programming of temperature limits, please mind,
that the inner temperature of Prophi is about 2°C above
the outer temperature.
The temperature limits can be set in the range of 0°C
and 98°C in1°C steps.
While programming, it is only possible to set the upper
temperature limit, when it is at least 1°C above the
lower limit.

Upper temperature limit

If the upper limit is ex-
ceeded, the ventilation
is switched on.

Lower temperature limit

If temperature is below
the lower limit, the
ventilation is switched
off.
Switching output
One of the relay out-
puts or the alarm out-
put can be used as
switching output of
Prophi.
If output 0 is assigned
to the ventilation control, the ventilation control is in-
activated.
Attention!
m
If one output has been programmed for ventila-
tion control, and additionally, it is programmed
as a fix stage or alarm output, the ventilation
control has priority.
