Water and Air Sensors for AXC Controllers
Input ST2 can be connected to a NTC sensor (additional to the internal sensor: by a
dip switch it is possible to choose which one to use) installed on the return air flow.
Input ST3 can be connected to a NTC sensor to measure the water temperature (to
be mounted downstream the valve). This sensor is used to acknowledge operation.
