Assembly
Wall-mounted control
• Do not place the control on parts of walls containing pipes or
electric cables but at about 150 cm from the floor.
• Do not place the control near heat sources, currents of air, direct
sunlight or in not well ventilated areas.
• Remove the locking screw in the upper left side to separate the
unit from the control (Fig. 2). Secure the unit on the wall and
mark the drill holes.
• Drill the holes previously marked.
Avoid drilling with the plastic unit already placed on wall.
• Remove the control connectors by exerting pressure as shown

in fig. 3. With the control connectors not in place prepare the
electrical connections between this and the electric control box
panel of the fan coil as shown in the wiring diagram in fig. 10.
For the specific connection between the control and the fan coil
unit refer to the diagram shown on the unit.
• Carry out the connections to the control connector (Fig. 4).
• After connections to the connector have been made, place it in
the corresponding housing on the unit.
• Fix the control to the wall using the corresponding screw anchors .
• Put the control cover back to its place by reinstalling the screw
previously removed (Fig. 2).
IMPORTANT:
• All connections between the unit and the control must be
placed into a proper plastic conduit.
• Handle the control with extreme care. Do not touch electronic
components to avoid damaging them.
• Do not forget to configure the dip-switches (if so required)
before closing the control.
• The control-unit connecting cable should be a PVC cable with
minimum section of 1 mm² or higher and shielded against
radio interference.
• Use a clip to join the control output cables (fig. 9).

Control is used in 2-pipe systems.

Functions

The "C" control permits to keep the internal temperature set using
the knob between 10 °C and 30 °C.

Fan operation


Use the speed selection button of the fan to select the manual or
automatic operating mode of the fan.

In manual mode it is possible to select three fan speeds (low/

medium/high) according to the need, or the economy mode.
In the auto mode fan speed is regulated by a microprocessor in the
control in relation to the temperature chosen.
During installation, it is possible to select continuous fan operation
via the switch located on the electronic board (see section dip-
swich configuration).
As an option, fan operation can be disabled during heating by
means of a sensor if water temperature is below 35°C, and during
cooling if water temperature is above 18°C.
These two functions allow improved comfort levels during winter by
avoiding undesired fan operation and during summer by turning the fan
coils on and oFF automatically in relation to the water temperature.
