Maintenance Minutes
This parameter adjusts the time during which the function will
continue activated once the selected temperature is reached.
The selectable value range is 10~99 minutes. The default factory
value is 10 minutes, and by means of
buttons it may
increase or decrease, respectively. Once the desired value has
been selected, press
button to save it.
For the anti-legionella function to raise the temperature of the tank to a temperature between
60~70 ºC, it is essential to install an auxiliary heat source in the tank (electric heating resistor,
auxiliary boiler, etc.). The
DUAL CLIMA heat pump will heat the water in the tank to 50 ºC and, from
this temperature, activate the auxiliary source to reach the adjusted temperature. If this auxiliary
heating source is not available, the heat pump will heat the water in the tank to 50 ºC and keep the
temperature for 80 minutes before deactivating the function.
NOTE: In case of not having an auxiliary heating source that allows raising the DHW
temperature above 60 ºC, the anti-legionella function will not ensure the eradication
of said bacteria.
6 ADDITIONAL FUNCTIONS
6.1 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 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. In addition, to reduce the noise impact, the outdoor fan will operate at low speed.
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
activated. To deactivate it, parameter P47 must be set to value 0 . 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.
