FWTSK
Temperature sensor
Installation and
operation manual
F
UNCTIONS
The temperature sensor is used to:
■ Fan control (figure 1: A=Cooling, B=Heating, C=Water
temperature)
■ Heating Element (if it is present as heating support) (figure 2:
A=Heating, B=Water temperature)
■ Cooling/Heating switching depending on water temperature
(figure 3: A=Summer, B=Winter, C=Water temperature)
P
ROBE CONNECTION ON CONTROLLER
■ Connect the temperature FWTSK sensor to the
remote control using the supplied cable as accessory
and, in case of prolongations, a shielded cable
only.
■ The shielding should be connected to the ground on
the fan coil side only.
■ The sensor cable (1.5 m) can be cut to measure
if necessary. Never place it near power supply
cables.
■ Open the controller after removing the screw of the
cover (figure 4)
■ Connect the probe to the connector and install it on
the circuit board as indicated in the diagram (figure 5)
■ Close the controller

NSTRUCTIONS FOR INSTALLATION
:
Use the special copper holder for the temperature sensor and position
it as described below, depending on the type of installation.
W
ARNING
:
Fan coil units for:
■
2 PIPE SYSTEMS - W/O VALVE: the sensor must be
positioned on the heat exchanger (figure 6).
■ 4 PIPE SYSTEMS - W/O VALVES: the temperature
sensor must be positioned on the exchanger of the
heating circuit (figure 7).
■ 2 PIPE SYSTEMS - WITH VALVE: the temperature
sensor must be positioned at the valve inlet, on the
branch coming from the system (figure 8).
■ 4 PIPE SYSTEMS - WITH VALVES: the temperature
sensor must be positioned at the heating valve inlet,
on the branch coming from the circuit (figure 9).
FWD - I
NSTRUCTIONS FOR INSTALLATION
:
Ex: Valves mounted on left side: (figure 10: A=Temperature sensor for
4 pipe system, B=Temperature sensor for 2 pipe system, C=Air)
W
ARNING
:
■ In the case of valveless FWD units for two-pipe sy-
stems, the temperature sensor must be positioned
on the pipe at the exchanger inlet.
■ In the case of valveless FWD units for four-pipe sy-
stems, the temperature sensor must be positioned
on the pipe at the heating circuit exchanger inlet.
FWB - I
NSTRUCTIONS FOR INSTALLATION
:
Ex: Valves mounted on left side: (figure 11: A=System pipe to be
provided by the user)
W
ARNING
:
■ In the case of valveless FWB units for two-pipe sy-
stems, the temperature sensor must be positioned
on the pipe at the exchanger inlet.
■ In the case of valveless FWB units for four-pipe sy-
stems, the temperature sensor must be positioned
on the pipe at the heating circuit exchanger inlet.
