Selecting the Underfloor Heating flow setpoint temperature (with SRAM2/EV kit option)
When the boiler is installed with the optional SRAM2/EV underfloor heating kit, the desired flow
temperature of the installation can be selected using the touch button as shown in the figure above.
To select the desired temperature, touch the "
+
" or "
-
" symbols to increase or decrease the
temperature respectively. When the temperature has been selected, the display will return to
standby mode after a few seconds.
The installation flow setpoint temperature can also be selected by using the MODE touch button to
browse to the “
underfloor heating installation flow setpoint
" display option. When this option
appears on the display, touch the "+ /-" symbols to select the desired temperature.
If you wish to disable the underfloor heating circuit function, select the setpoint value "
OFF
" by
touching the "-" symbol until this value appears on the display.
The flow setpoint temperature range permitted is OFF and 0 - 45ºC. To obtain optimum performance
from the underfloor heating system installed, we recommend selecting a setpoint temperature of 25
- 35 ºC, providing this is permitted by the heating system installed and the insulation in your home.

OPERATION
The
Evolution EV HAM
boiler is designed to heat a heating installation and provide instantaneous
domestic hot water. Optionally, an Underfloor Heating Kit (SRAM2/EV) and/or a second heating circuit,
heating circuit 2, may be connected to the installation to improve its performance.
12.1
Heating Function
In this mode, the boiler can heat up the heating installation. To do this, select the desired boiler
setpoint temperature (see "
Selecting the boiler setpoint temperature
") and the temperature of room
thermostat 1 (
TA1)
. The burner will switch on. When the boiler reaches 60ºC it is ready to heat up the
heating installation and will start up the heating pump for this purpose. The burner will shut down
when the boiler reaches the adjusted setpoint temperature. The heating pump and the burner will
stop when the room temperature reaches or exceeds the temperature set on the installation’s room
thermostat (if it has one). If a hot tap is turned on, the instantaneous DHW production function will
start up and provide constant domestic hot water at the selected DHW setpoint temperature.
The boiler heating function can be totally disabled (
Summer
mode) by selecting "
OFF
" as the boiler
setpoint value. In this operating mode, only the instantaneous DHW production function will remain
enabled.
NOTE: When the heating function is disabled, circuit 2 will also be disabled if it is connected.
