INSTALLATION AND MAINTENANCE

The procedures for installing the user interface, the power
board and probes, with specific instructions for individual
hydronic units of the Daikin range, will be described at a
later stage.

PROBE INSTALLATION

The FWECSA controller manages the following probes:
• Air temperature reading probe installed inside the
user unit; it does not require any special installation
operations.
• Probe (optional and alternative to the previous one)
connected to the I/O board for temperature readings of
the air taken in by the machine, or in any other point of
the room subject to temperature adjustment (REMOTE
AIR PROBE)
• Probes (optional) for water temperature readings: it is
possible to connect one or two probes, depending on
whether the unit is connected to a 2- or 4-pipe system.
• Probe (optional) to read the relative ambient humidity,
connected to the I/O board
To avoid interference, and subsequent faulty
operation, the probe cables must NOT be set
up near power cables 8230V).

REMOTE AIR PROBE INSTALLATION

Use of the remote air probe to adjust the room temperature
is optional. When it is used, it becomes the main adjustment
probe, in place of the probe installed inside the user unit. It
is always possible to choose the main room temperature
adjustment probe from the "air probe" parameter contained
in the CONFIGURATION MENU.
The remote air probe must always be connected to clamps
I1-C1 on the I/O board.
