These controls make room temperature adjustment (with

offset settable from the keyboard) completely autonomous

through the AUTO, SILENT, NIGHT and MAX programmes

by means of a probe located in the lower part of the device,

ensuring anti-freeze safety even when set to stand-by.

The control panel has a memory, so settings will not be

lost if the appliance is switched off or in the power supply

is cut.

Controls cannot be installed on the FWXM-series.

After 20 seconds from the last action the panel

brightness will be reduced for improved night-time

comfort, and the room temperature will appear on the

display. Press any key to restore maximum brightness.

The 10 kΩ water temperature probe positioned in the

device battery regulations the minimum level when heating

(30°C) and the maximum level when cooling (20°C).

The various functions are set using 8 backlit keys:

Any statuses and alarms are also shown on the display by

using 8 specific symbols:

In order to manage the device via the control panel, this

must be connected to the mains electricity.

If a general switch is installed on the power line, this must

also be switched on.

- Turn the device on by activating the general switch

One of the two symbols flashing means that the water

temperature (hot or cold) is not sufficient, and stops

the fan until the temperature reaches a level suitable for

reaching the required temperature.

If after switching the power on the board detects the

H2 probe, start-up occurs in normal conditions with the

minimum and maximum thresholds.

The board also has a function when there is no H2 probe,

in such cases the fan stop thresholds are ignored.

When the control is in this operating mode, anti freezing is

in any case guaranteed. If the ambient temperature drops

below 5°C, the solenoid valves on the hot water output

and the boiler are opened.

The adjustment range is from 16 to 28°C in intervals of

0.5°C, but out-of-range values are also accepted, from

5°C to 40°C (unless in auto mode).

Only set these values for brief periods, and then set a

intermediate value.

The controller is very precise - set it to the required value

and wait for the controller to regulate itself according to the

actual room temperature detected.

To activate the device

Key Operation Display

Keep the Heating / Cooling key pressed for approx. 2 seconds to change the mode

between heating and cooling, which is indicated by the 2 symbols that appear if heating

or cooling is active.

When heating, the symbol displays when the set point is higher than ambient

temperature, both are off when the set point is lower.

When cooling, the symbol displays when the set point is lower than ambient temperature,

both are off when the set point is higher.

Key Operation Display

Press and hold the ON Stand-By key for approx. 2 seconds. No illuminated signals on

the display at all means that the system is in stand-by (no operation). Off

Ventilation speed adjustment is carried out automatically

between the minimum and maximum values, according to

the distance of the actual room temperature from the set

point, according to a PI-type algorithm.

Ventilation speed is limited to a contained maximum value.

By selecting this mode, ventilation speed is limited to a

very contained level and the set temperature is adjusted

automatically, as follows:

- decreases by 1°C after one hour and by another degree

after two hours in heating mode;

- increases by 1°C after one hour and by another degree

after two hours in cooling mode;

In this operation mode, the maximum possible power level

is activated whether heating or cooling.

Once the desired room temperature is reached, we

recommend selecting one of the other 3 operation modes

for increased comfort and sound levels.
