2.3.2 Enable Water Inlet Temperature Probe
In the case of a dry cooler, it is possible to enable, via parameter PH19, an optional temperature probe that measures
the inlet water temperature to the exchanger. The temperature detected has no effect on the regulation, but results
usable to user through the Probes screen or by MODBUS.
The ambient temperature and indoor temperature probes too can be disabled by parameters PH18 and PH09
respectively.
Attention: disabling these probes heavily impacts on the management of spray and adiabatic panels, and on the
antifreeze functions implemented by the controller. Proceed to these settings with extreme caution; the user
becomes responsible for any malfunctions or breakages, caused by the low temperature, which may occur.
