based on the air temperature
AI
The controller selects the cooling or heating mode based
on the temperature of the air compared to a neutral
temperature interval (neutral zone) centred on the set
value of the thermostat.
When this function is selected, the
temperature range of the thermostat refers to
the values indicated in figure 3, both for
cooling and for heating.
In this type of configuration, the input for the
centralised cooling/heating switching mode is
disabled.
Selecting the range of the neutral zone
The neutral zone is a parameter related to the function
"automatic cooling/heating switching mode based on the
air temperature".
The neutral zone is a temperature interval astride the set
temperature. When the air is warmer than the top limit of
the neutral zone, the cooling mode is selected.
When the air is cooler than the lower limit of the neutral
zone, the heating mode is selected.
The following figure illustrates an example with:
Neutral zone = 5°C
Set room air temperature = 21°C
For temperatures above 23.5°C the cooling operating
mode is selected
For temperatures below 18.5°C the heating operating
mode is selected.
Neutral zone
<18.5°C =
>23.5°C =

°C21°C
On the controller, the range of the neutral zone is 2°C or
5°C and can be defined by setting microswitch number 4
(see "Setting the microswitches" on page 10).
Position of microswitch no. 4
Range of the neutral zone
ON 2°C

Time function
The time function is used to start the fan at medium
speed for 2 minutes at regular intervals (every 10
minutes) once the room temperature has reached the
level as set on the thermostat. It ensures the constant
monitoring of the air temperature in the room. It is only
used in summer and only if the enabling signal of the
water temperature probe is positive.
The time function cycle is also executed when the
controller is powered (first start-up or voltage reset).
The thermostat and the operating mode
selector switch are disabled when the time
function is in use.
The time function can be used only for units
without valves and only in summer.
The time function is not foreseen for the
ECFWER6 and ECFWDER6 versions.

Electric heater control
The thermostat controls an electric heater as integration
or replacement of a hot water heating system.
When the operating mode selector switch is turned
to and the electric heater is turned on, the fan runs
continuously at medium speed.
For safety reasons, the fan is turned off 2 minutes after
the electric heater is turned off, whether this occurs
when the desired air temperature is reached or when the
electric heater is turned off manually using the operating
mode selector.
■
During operation of the electric heater, the
fan runs at medium speed only.
■
During heating operation of 2-pipe system
units equipped with an electric heater and
motorised valves, only the electric heater
works.
Fan coil enabling system based on the water
temperature
The controller starts the unit according to the following
logic based on the water temperature that is detected by
a dedicated probe:
■
Water temperature <17°C: Cooling mode enabling
signal
■
Water temperature >37°C: Heating mode enabling
signal
In installations with electric heater control, the same
probe sends the enabling signal for the electric heater to
turn on according to the following logic:
■
Water temperature <37°C: Additional electric heater
enabling signal. (This enabling signal is sent only if
the operating mode selector switch is turned
to ).
■
Water temperature >39°C: The additional electric
heater is switched off.
For switching based on water temperature, the
supplied water probe needs to be installed.
See "Position of the water temperature probe"
on page 11 for installation of the water
temperature probe.

AUTODIAGNOSIS PROCEDURE
For checking the correct operational efficiency of the
controller when installing or for searching for possible
faults, all outputs can be operated manually (fan, valves,
electric heater) thanks to the autodiagnosis mode.
Proceed as follows to access the autodiagnosis mode
and to run the tests
1 Tu rn the operating mode selector switch to the "OFF"
position.
2 Tu rn the knob of the thermostat anti-clockwise until it
reaches the minimum temperature position.
3 Hold the cooling/heating selector pushed for at least
5 seconds. At this stage both LEDs light up.
4 Within 5 seconds, turn the knob of the thermostat
clockwise to the maximum temperature position. The
red LED switches off and the blue LED remains lit to
indicate that the autodiagnosis mode has been
accessed.
NOTE
If you wait more than 5 seconds before
turning the knob again, the autodiagnosis
mode will be automatically exited.
5 In the autodiagnosis mode, each position of the
operating mode selector switch corresponds to the
simulation of an output.
Position Output Terminals
Valve N-V
Minimum speed N-V1
Medium speed N-V2
Maximum speed N-V3
Electric heater
or second valve
N-RE
By running through the various positions of the
operating mode selector switch, the electronic
controller outputs can be checked one after the other
either by observing the related component (valve,
fan, electric heater) or by checking if the
corresponding terminals are powered at a voltage of
230 V.
NOTE
If the operating mode selector switch is not
moved for more than one minute, the
autodiagnosis mode is automatically
exited.
6 Exit the autodiagnosis mode by turning the operating
mode selector switch to the position.
