14 DUAL CLIMA R
Parameter P46
Parameter P46 will adjust the slope of the
curve and the maximum temperature of the
Heating mode. The selectable value range is
30~50 ºC. The default factory value is 45 ºC
and this value can be increased or decreased
by marking the desired value in the displayed
submenu. Once the desired value has been
selected, press the
"Ent" button to save said
setting.
NOTE: An incorrect adjustment of these operating curves may cause the heating
installation not to generate the desired comfort in the home, failing to provide
heating in extreme weather conditions of cold and/or causing overheating in hot
weather conditions.
4.10 Night Mode
With the aim of reducing the number of activations and the sound impact of the heat pump during
particularly sensitive times (night), the
DUAL CLIMA R heat pump allows the activation of the Night
operating mode. During the Night operating mode, the DHW will automatically raise the adjusted
setpoint temperature by +3 ºC, the Heating mode will automatically reduce its setpoint temperature
by -2 ºC, and finally, the Cooling mode will automatically raise its setpoint temperature by +2 ºC.
To activate and configure this operating mode, parameters P47 , P48 and P49 should be set in the
Technical menu (see
"Technical Menu"
). The heat pump is supplied by default with the Night mode
disabled. To activate it, parameter P47 must be set to value 1. In addition, the start time of Night
mode will be selected through parameter P48 while the end time will be selected through parameter
P49 . The pre-adjusted factory time is from 10:00 pm to 06:00 pm.
4.11 Anti-Legionella function
This function prevents the proliferation of Legionella bacteria in the domestic hot water stored in the
tank, so it will only be available if the installation has a connected Domestic Hot Water tank and the
heat pump is configured for it. In addition, in order to make the function effective, it will be essential
for the tank to have a heating component installed, in order to reach the temperatures required to
eradicate the bacteria.
To activate this function the parameter P53 should be set in the Technical menu (see
"Technical
Menu"
). The heating pump is supplied with this function disabled, to activate it the value of parameter
P53 should be set to 1 .
The function will periodically raise the temperature of the Domestic Hot Water from the tank to a
temperature of 60~70 ºC. To do this, the desired temperature and periodicity can be selected (see
"Temperature Selection"
). This function will be activated regardless of the operating modes that are
activated at the time of starting, even when the heat pump is in Standby mode.
In addition, as long as the function is enabled ( P53=1 ), it is possible to activate this function manually,
through parameter P80 of the Service Menu (see
"Service Menu"
). Set the parameter P80 to 1 to
activate the anti-legionella feature once. Once the function is activated, it is not possible to stop it and
it will have to wait until it finished, in order that the machine returns to its normal operation.
