• INSTRUCTION FOR THE INSTALLATION OF THE T3 AIR PROBE
If the minimum probe is used, proceed as follows:
insert the minimum probe between the coil fins
keeping it slightly tilted downwards. Connect the
probe to the T3 connector on the power board.
• T2 PROBE FOR CHANGEOVER (Optional)
Only on fan coil units in two-pipe system versions,
the summer/winter changeover can take place
automatically by applying the ChangeOver T2 probe
(optional) to the water pipe that supplies the coil. The
probe must be positioned upstream of the three-way
valve.
Depending on the temperature detected by the probe,
the device is set for summer or winter operation.
When using the T2 probe in installations with Master
and Slave units, the T2 probe must be installed on all the
devices.
