positioned near the aperture without any furniture or other obstruction in between.
4.3 Temperature calibration
If after several days’ operation of your radiator, you notice a
discrepancy between the temperature observed in your room and the
programmed temperature on the appliance, you can recalibrate the
radiator in 0.1°C intervals, using the following procedure.
Press the MODE key for 5 seconds to access advanced functions. Then press
the MODE key several times until the radiator calibration function appears (see the
beginning of this section for more details).
1) The calibration function displays the temperature measured by your
appliance (e.g.: the appliance displays 19.0°C).
2) Measure the room temperature near the radiator using a reference
thermometer (e.g.: the thermometer displays 20.0°C). NOTE: your ther-
mometer must be placed about 2m from the radiator, with no obstacle
between them .
3) If the temperature measured differs from that indicated by your appliance,
press the – or + keys to make them match (e.g.: press the + key several
times until your screen shows 20.0°C).
4.4 Setting open window detection threshold
Refer to the introduction to this chapter to access the functions menu and how
to browse them.
Your radiator goes to open window mode when it detects a 1°C temperature drop
(via the probe) under given conditions and within a set interval of time.
If your radiator goes to open window mode without cause
(detecting a window open when that is not so), you can adjust the
detection level of your probe.
The detection threshold is adjustable from 1 to 3°C, in 0.5°C
steps; the default value is 1°C.
The value displayed shows the number of half-degrees:
2
=> 0.5 x 2 = 1°C (default)
3
=> 0.5 x 3 = 1.5°C
4
=> 0.5 x 4 = 2°C
5
=> 0.5 x 5 = 2.5°C
6
=> 0.5 x 6 = 3°C
Press the – or + keys to set the threshold preferred.
4.5 PlC association / disassociation
Refer to the introduction to this chapter to access the functions menu and how
to browse them.
Your appliance can be controlled remotely by a PLC programming base unit
using X2D protocol (not supplied with your appliance). Once associated with it, your
radiator can communicate with this base unit via the electrical network in your home
without the addition of an extra control panel.
If your radiator is associated with a pilot wire or PLC programming base unit,
please see the instructions supplied with the unit for information on operating your
appliance with it.
To associate the base unit with your radiator, first of all activate
the association procedure of your base unit. Then press the – or +
key on your radiator until the CP + v symbol is displayed.
To disassociate your radiator, press the – or + key for 30
seconds until the CP + o symbol is displayed.
