Installation of the F module
The F module uses the installation space of the A and P modules.
The existing functions in the combination of A and P modules are
covered by the F module. To control the hygiene parameters, an M
module is always required. The sensors for pH, redox, temperature
and sample water flow monitoring are connected to the M module.
You can also connect the external DIN contact to the M module.
