Cool Cells

The controller can control one cool cell output. This
cooling system reduces the air temperature by
evaporation of water into the air stream.
Principle of operation
The cool cell output can either operate according
to the inside temperature or outside temperature:
it starts running in timer mode when the inside (or
outside) temperature rises and reaches the output's
start temperature; the output stops when tempera-
ture falls below a user-defined value. It can also
stop when humidity levels are too high (see RH
Compensation in chapter 10).
If the cool cell output operates according to the
inside temperature, its start and stop temperatures
are related to the set point; this means they are
automatically adjusted when the set point changes.
That is not the case if cool cells operate according
to the outside temperature.
