Installation Of The Remote Air Probe; Installation Of The Water Probe - Daikin FWTOUCH Manuel D'installation Et D'utilisation

10.2 INSTALLATION OF THE REMOTE AIR PROBE

The use of the remote air probe for regulating
the room temperature is optional. When used,
it becomes the main regulation probe in place
of the probe located in the user interface. In any
case it is always possible to choose the main
room temperature regulation probe by means
of the "air probe" parameter contained in the
CONFIGURATION MENU.

10.3 INSTALLATION OF THE WATER PROBE

The water temperature probe (white cable) is an
optional accessory.
In the case of 2-pipe hydronic indoor units (sin-
gle coil), the water probe must be connected to
terminals L2 - IC of the circuit board.
In the case of 4-pipe hydronic indoor units, it is
possible to choose (using the "Number of wa-
ter 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 in-
stalled in such a way as to read the temperature
of the heating water (i.e. installed on the hot wa-
ter coil) and connected to terminals L2 - IC of
the circuit board.
If instead you choose to use two water probes,
the probe for reading the cold water tempera-
ture must be connected to terminals L2 - IC of
the circuit board, and the probe for reading the
hot water temperature must be connected to
terminals L3-IC of the circuit board.
FWV/L/M-D & FWZ/R/S-A
Use the special copper holder for the water
probe and position it as described below, de-
pending on the type of installation.
Fan coil units for:
Ū 2-PIPE system - W/O VALVE or WITH 2-WAY
VALVE: the water probe must be positioned
on the heat exchanger (Fig.11.8);
Ū 4-PIPE system - W/O VALVE or WITH 2-WAY
VALVES: the water probe (if one only) must
be positioned on the heating circuit's heat
exchanger (11.9 p. 146); the second probe,
if any, must be positioned on the cooling cir-
cuit's heat exchanger;
Ū 2-PIPE system - WITH 3-WAY VALVE: the wa-
ter probe must be positioned at the valve
inlet, on the branch coming from the system
The remote air probe must always be connected
to terminals L1-IC of the circuit board.
FWV/L/M-D & FWZ/R/S-A
Use the plastic adhesive probe holder provided:
Ū Fan coil unit without
(11.5 p. 145)
Ū Fan coil unit with support base (11.6 p. 145)
Ū Fan coil unit with front intake (11.7 p. 145)
(11.10 p. 146);
Ū 4-PIPE system - WITH 3-WAY VALVES: the wa-
ter probe (if one only) must be positioned at
the heating valve inlet, on the branch coming
from the circuit (11.11 p. 146); the second
probe, if any, must be positioned at the cool-
ing valve inlet on the branch coming from
the circuit.
FWD-A/FWN-A
Example, valves mounted on the left side
(11.12 p. 146):
Ū In the case of valveless FWD-A/FWN-A hy-
dronic indoor units, for two-pipe systems, the
water probe must be positioned on the pipe
at the heat exchanger inlet.
Ū In the case of valveless FWD-A/FWN-A hy-
dronic indoor units, for four-pipe systems, the
water probe must be positioned on the pipe
at the heating circuit heat exchanger inlet.
FWB-C/FWP-C
Example, valves mounted on the left side
(11.13 p. 147):
Ū In the case of valveless FWB-C/FWP-C hy-
dronic indoor units, for two-pipe systems, the
water probe must be positioned on the pipe
at the heat exchanger inlet.
Ū In the case of valveless FWB-C/FWP-C hy-
dronic indoor units, for four-pipe systems, the
water probe must be positioned on the pipe
at the heating circuit heat exchanger inlet.
