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.
FLAT - ESTRO
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.

Use the copper probe-holder for the water probe (white cable)
and, depending on the case, set it up as described below.
For two-pipe units without valve, the water probe must
be installed on the exchanger using the supplied strap
(figure 13);

OPERATION MANUAL
IT IS strictly forbidden to reproduce this manual, even partially
For four-pipe units without valves, the water probe
must be installed on the exchanger in the heating circuit
(figure 14);
For two-pipe units with valve the water probe must be
positioned on the valve entrance, on the branch coming
from the system (figure 15);
For four-pipe units with valves, the water probe must be
installed on the heating valve entrance, on the branch
coming from the circuit (figure 16).
