The temperature sensor is used to:
n Fan control (figure 1: A = Cooling, B = Heating,
C = Water temperature)
n Heating Element (if it is present as heating support)
(figure 2: A = Heating, B = Water temperature)
n Cooling/Heating switching depending on water
temperature (figure 3: A = Summer, B = Winter,
C = Water temperature)

n Connect the temperature FWTSK sensor to the
remote control using the supplied cable as accessory
and, in case of prolongations, a shielded cable only.
n The shielding should be connected to the ground on
the fan coil side only.
n The sensor cable (1.5 m) can be cut to measure if
necessary. Never place it near power supply cables.
n Open the controller after removing the screw of the
cover (figure 4)
n Connect the probe to the connector and install it on
the circuit board as indicated in the diagram (figure 5)
n Close the controller

Fwl m v instructions For installation
Use the special copper holder for the temperature sensor
and position it as described below, depending on the type
of installation.
Fan coil units for:
2 pipe systems - without valve: the
sensor must be positioned on the heat
exchanger (figure 6).
4 pipe systems - without valves: the
temperature sensor must be positioned on
the exchanger of the heating circuit
(figure 7).
2 pipe systems
temperature sensor must be positioned at
the valve inlet, on the branch coming from
the system (figure 8).
4 pipe systems
temperature sensor must be positioned at
the heating valve inlet, on the branch
coming from the circuit (figure 9).

n In the case of valveless FWD units for two-
pipe systems, the temperature sensor must
be positioned on the pipe at the exchanger
inlet.
n In the case of valveless FWD units for four-
pipe systems, the temperature sensor must
be positioned on the pipe at the heating
circuit exchanger inlet.
