7.10 DHW INTEGRATING ELECTRIC RESISTANCE

For an eventual integration in heating of DHW, it is possible to automa-
tically manage an electric heater found in the DHW storage, through the
USER INTERFACE and a specific DHW temperature sensor (NTC probe
on terminals 5-6 and parameter 123 = 0).
The intervention of the electric resistance happens if, after the delay time
(parameter 131), the domestic request has not been satisfied yet.
The electric resistance is switched off once the set point temperature, de-
fined with parameter 132, is reached.

7.11 DEHUMIDIFIER MANAGEMENT

To monitor ambient humidity, it is possible to operate a dehumidifier.
If dehumidification is required, L phase is made available to terminal G of
the TERMINAL BLOCK; it is then possible to control the dehumidifier
ignition through a relay connected between terminal G of the TERMINAL
BLOCK and neutral terminal N of the terminal board.
Pump 1 is also enabled, then the PdC part cooling.
A demand for dehumidification occurs only in cooling mode in the following
cases:
- Attach a separate humidistat to terminals IN and COM.
- If the KCTR is installed, when the relative humidity detected by the sen-
sor placed inside it is higher than the set point Set (parameter 119) +
differential (parameter 120)
If the contact is closed COM IN and activates the alarm generation of con-
densate, then open the output I (ie P2 turns off if installed) and the output
is enabled G (if the mode is active cooling) so turning on the dehumidifier.

7.12 ROOM THERMOSTAT OUTPUT

This outlet is strictly linked to KCTR use.
When the room temperature detected by the sensor placed inside it not
satisfies the Set point (parameters 200÷203), L phase is made available
to C terminal of the TERMINAL BLOCK; if to the contrary, the L phase is
available to terminal D.
This way, it is possible to pilot the ignition of an air conditioning terminal
via a relay connected between terminal C of the TERMINAL BLOCK and
neutral terminal N of the terminal board.
Note: Terminal E of TERMINAL BLOCK is always avaiable in L phase.

7.13 COMFORT/ATTENUATION TIME PERIODS

In case the KCTR is used it is possible to set the environment Sets, de-
fined by "Comfort" (par. 200 in heating, par. 202 in cooling).
If at certain times of the day the need for comfort isn't needed, for example
outside or in the night hours, it is possible to mitigate these Sets, which
become of "Attenuation" (par. 201 in heating, par. 203 in cooling).
Using parameters 205 and 206, it is possible to set the time of day in which
one can force, respectively, the transition to the comfort and attenuation
Sets.
With the 204 parameter, or with brief touch on the "up arrow" key of the
KCTR one can force the Set change, if in comfort one passes to attenua-
tion, and vice versa. This can be useful if, for example, I'm leaving home
and I want to rapidly pass to attenuation.
NOTE:
By default the comfort Set is always active, and if one manually forces
the change to the attenuation Set, at the end of the day (00:00 o'clock), it
automatically returns to comfort.
