Type D Electronic Control
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.
• The connecting cable of the fan coil unit and the accessory cables
should be of the H07 RN-F type (or higher) according to
EN 60335-2-40 standard.
All electric connection cables should be at least 1,5 mm.
• Carry out the connections to the control connectors (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).

Functions
Control "D" have a knob to select the temperature, with a range
from 10°C to 30°C, and room temperature is maintained at the
selected value.
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-
switch configuration).
In the heating mode, the fan operation is delayed by approximately
one minute to allow the residual heat on the heat exchanger coil or
the electric heaters (if any) to be released.
Frost - protection
This function keeps the temperature from dropping below 7°C in rooms
not used for long periods of time. When this temperature is reached,
the control activates the valve and puts the fan on high speed. The
frost protection function can be activated through the associated micro-
switch (see section dip-switch configuration); if enabled, this function
activates even when the control is in the OFF position.
