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.
