Slide the control panel into its housing in the upper part
of the device and fix it with the two fixing screws (ref. A).
To install the connection box:
- open the box (ref. B);
- lock the lower tooth into its hole (ref. C) on the side of
the device;
- hook the upper part of the box to the side (ref. D);
- fix it with the two fixing screws (ref. E);
- connect the grounding cable to the unit structure (ref.
M) using the fixing screws (the minimum force that
must be applied for tightening screws must be around
2N);
- connect the fast connector of the MOTOR to the other
on the board (ref. I) *;
- on the two GRID block terminals (ref. L) there is a
bridge that allows FWXM-series to work without a
microswitch.
For versions in-built into the formwork, follow the
microswitch connection instructions on the instruction
sheet of the vanity panel.
For other versions, remove the bridge and connect
the two terminals originating on the grill safety
microswitch*;
- connect the water probe connector (ref. F) on the unit.
The water temperature probe controls the temperature
inside the batteries and determines when the fan starts
according to pre-set parameters (minimum operation
in winter and maximum in summer).**
Check that they are correctly inserted into the
compartment on the battery.
- Connect the electrics, tidy cables and fix them with
the three clevises supplied (ref. G);
- close the box with the 4 screws (ref. H);
- refit the vanity plate on the side of the unit;
- tighten the upper screws on the control panel;
- place the screw head covers in their housing on the
control panel;
*N.B.: * For versions with hydraulic connections on the
right, refer to the relevant paragraph
** If after switching the power on the board detects the
H2 probe, start-up occurs in normal conditions with the
minimum and maximum functions.
The board also has a function when there is no H2 probe,
in such cases the fan stop thresholds are ignored.
The on-board controller is a panel with 8 capacitative keys
and amber display that contains the AUTO function (step
ventilation adjustment).
The EKRTCTRL2 thermostat can be set from 5 to 40°C,
has a winter and summer selector and the 10 kΩ water
temperature probe positioned in the compartment on the
battery regulations the minimum level when heating (30°C)
and the maximum level when cooling (20°C). It is suitable for installing on board and has a 230V output for controlling
a solenoid valve.
The board also has a function when there is no H2 probe,
in such cases the fan stop thresholds are ignored.
