tecHnical / application notes
pipe sensor operation: A pipe sensor can be connected when the
thermostat is configured for either 2-pipe or 4-pipe fan coil operation (see
JP4 jumper configuration). The Pipe sensor is used to determine the
water temperature in the Main Coil. The Pipe Sensor should be mounted
on the Main Coil supply and wrapped with insulating material.
