Controller for units

FWECSA

FWV, FWL, FWM, FWZ, FWR, FWS

Use the supplied adhesive plastic probe-holder:

• 

Fan coil without base 

(figure 05)

• 

Fan coil with base 

(figure 06)

• 

Fan coil with front suction 

(figure 07)

HUMIDITY PROBE INSTALLATION

The humidity probe is an optional accessory. If one is 
installed, it must be connected to the SU-SU clamps on 
the I/O board. The probe sensor can be positioned where 
it will be in contact with the air flow of the unit's suction 
circuit (if there is also a remote temperature probe, strap 
them together as illustrated in the figure below) or in any 
other point in the room subject to temperature and humidity 
adjustment.

IT IS also possible to position the probe sensor inside the 
user unit using the relative hook on the base of the unit 

(figure 08)

.

The cable supplied with the humidity sensor is equipped 
with a shield. There is no need to connect this shield to 
the I/O board. If interference from near-by power cables or 
other is affecting the relative humidity reading, connect the 
aforementioned shield to the GND clamp on the RS485 serial 
por t. 

WATER PROBE INSTALLATION

The water temperature detection probe (white cable) is an 
optional accessory.
With 2-pipe units (single coil) the water probe must be 
connected to clamps I2 - C1 of the I/O board. With 4-pipe 
units it is possible to choose (through the "Number of 
water probes" parameter in the CONFIGURATION MENU) 
how many probes (one or two) to use. If you choose to 
use a water probe, it must be installed so that it reads the 

temperature of the heating water (and is therefore installed 
on the hot water coil) and must be connected to clamps 
I2 - C1 of the I/O board. If, on the other hand, you choose to 
use two water probes, the cold water detection probe must 
be connected to clamps I2 - C1 of the I/O board, whereas 
the hot water detection probe must be connected to clamps 
I3 - C1 of the I/O board.

FWV, FWL, FWM, FWZ, FWR, FWS

Use the copper probe-holder for the water probe and, 
depending on the case, set it up as described below. Fan 
coils for:

• 

2-PIPE system - NO VALVE or 2-WAY VALVE: the water 
probe must be set up on the exchanger 

(figure 09);

• 

2-PIPE system - NO VALVE or 2-WAY VALVE: the water 
probe (if single) must be set up on the exchanger in the 
heating circuit 

(figure 10)

; any second probe must be 

installed on the exchanger in the cooling circuit;

• 

2-PIPE system - WITH 3-WAY VALVE: the water probe 
must be positioned on the valve entrance, on the branch 
leading out from the system 

(figure 11)

;

• 

4-PIPE system - WITH 3-WAY VALVES: the water probe 
(if single) must be positioned on the entrance of the 
heating valve, on the branch leading out from the circuit 

(figure 12)

; any second probe must be installed on the 

entrance of the cooling valve on the branch leading out 
from the circuit.

• 

For FWD units without valves, for 2-pipe systems, 
the water probe must be positioned on the pipe at the 
entrance of the exchanger.

• 

For FWD units without valves, for 4-pipe systems, 
the water probe must be positioned on the pipe at the
