Destratification cycle
This function prevents stratification of the air and a better temperature reading from the remote sensor on the fan's return.
If there is no regulation and the fan is off (
I28
=0), you can start the destratification function in relation to the season.
To start the function in both heating and cooling modes, set
I38
=1.
To start the function in heating mode only, set
I38
=2.
To start the function in cooling mode only, set
I38
=3.
When the destratification function is active, the fan starts at speed 1 and the icon flashes for the time set in
I39
every in-
terval set in
I40
.
22.
Dirty filter
The dirty filter function counts the hours of operation of the fancoil and displays a warning message with the icon
when the
counter exceeds the number of hours set in parameter
I41
.
The filter is then considered to be dirty and must be changed.
To activate the dirty filter function, set the maximum number of hours with
I41
(not equal to zero).
To deactivate this function, set the maximum number of hours with
I41
=0.
When the function is active, the fancoil hours counter is saved to memory every 2 hours. To reset the counter, set
I51
=1. The
counter is then reset, parameter
I51
sets itself to 0 automatically and the icon
stops flashing until the counter exceeds the
value of
I41
again.
N.B.: when the function is deactivated, the fancoil hours are not counted.
23. Window contact
In all modes, when a digital input is used as the window contact
M03
=4 or
M05
=4 or a remote sensor is configured as window
contact
M07
=7,
M09
=7 or
M11
=7, the outputs are disabled if the window contact is open.
The icon
flashes when the window contact is considered open.
If an electric resistance is active (
M02
=1, 2 or 3) ventilation is stopped after delay
I35
has expired so as to disperse the heat
generated by the resistance.
24. Summertime changeover
The device is configured to change to summertime automatically in certain areas of the world.
To use this function, set
I46
=1 if the controller is in use in Europe.
Set
I46
=2 for the USA. In the last case, also set the unit of measurement to °F by setting
I45
=1. All temperature parameters
will then be expressed in °F and the controller will use this unit automatically.
For all areas outside Europe and the USA, set
I46
=0. The change to summertime is not automatic in this case. You must set
the time manually depending on local regulations.
25. Sensor AI3 used as input 0...10V
If sensor
AI3
is used as 0...10V input, set the jumper JP1 on position 2-3 and set parameter
M11
to 10. Then set the scale for
this input by parameters
I55
(low limit of scale) and
I56
(high limit of scale). Set parameter I43 to 12 in order to visualize the
corresponding measure. For corresponding unit set parameter
I57
(0=ppm, 1=%r.h., 2=no unit). It is possible to correct the
value visualized by parameter
I58
.
The value visualized on the display can be with or without decimal point based on the range of the scale.
