When the boiler is installed with the optional underfloor heating kit, SRAC2/EV, the desired flow
temperature of the installation can be selected using the push-in button as shown in the figure

will appear on the display and
you will see the set point temperature selected. When you have selected the temperature, push the
button in again. The display will return to standby status after ten seconds..
The installation flow set point temperature can also be selected by browsing with the set button
until

appears on the display. Then turn the push-in button to select the desired temperature.
The set point temperature range that can be selected is 0 - 45 ºC. To obtain optimum performance
from the underfloor heating system, we recommend selecting a set point temperature of 25 - 35 ºC,
providing the heating system installed and the insulation in your home permit this.

FUNCTIONING
The
Evolution EV AC
boiler is supplied by default in “heating only” mode, for a heating installation
only. Optionally, a domestic hot water storage heater (Sanit) and/or an underfloor heating kit
(SRAC2/EV) may be installed, providing the installation with more features.

In this mode, the desired set point temperature for the boiler should be selected, and the
temperature of the room thermostat or E20 remote control (if the appliance is equipped with
these). The burner and the heating pump will begin to function until the selected set point
temperature of the boiler is reached in the installation (or on the room thermostat, if the appliance
is equipped with one). When the temperature of the installation drops below the boiler
temperature selected, the burner will start the heating cycle up again.
