Domestic Hot Water production function
In this mode, the boiler provides instantaneous DHW. To activate this mode, select the desired DHW
setpoint temperature (see "
Selecting the DHW setpoint temperature
"). The burner will ignite until
the boiler reaches 60 ºC. If a hot tap is turned on, the instantaneous DHW production system will start
up and provide constant hot water at the selected setpoint temperature.
The
Evolution EV HAM
boiler is equipped with system for modulating instantaneous DHW
production and
progressive adjustment
of the Domestic Hot Water consumption temperature:
-
The modulation
allows the boiler power to constantly adapt to the hot water consumption
requirements at all times, without altering the efficiency of the boiler. Consumption savings are
thus obtained together with improved boiler functioning and lower emissions.
-
Progressive electronic adjustment
of the DHW temperature, a system designed by DOMUSA
TEKNIK, enables the DHW consumption temperature to be stabilised at the temperature selected
using the button on the control panel, and a constant hot water temperature with no variations
is obtained
regardless of the water flow required and the cold water inlet temperature at any
given time.
This enables optimum hot water comfort and adaptation to each user’s particular
needs.
If you wish, you may totally disable the domestic hot water production function by selecting "
OFF
" as
the DHW setpoint temperature.

Functioning with an SRAM2/EV Underfloor Heating Kit (Optional)
The
Evolution EV HAM
boiler may be used with an SRAM2/EV Underfloor Heating Kit (fitted to
heating circuit 1). This kit basically consists of a motorised 3-way mixing valve, a circulation pump
and an underfloor heating installation flow temperature sensor. For correct hydraulic installation,
carefully follow the assembly and connection instructions enclosed with the kit.
The underfloor heating installation is worked by the electronic boiler control. The installation flow
sensor is used to adjust the temperature, selecting the installation flow setpoint temperature using
the boiler setpoint adjustment touch button on the control panel, between OFF, 0 and 45 ºC (see
“
Selecting the Underfloor Heating flow setpoint temperature
”). In this operating mode, the electronic
control sets the boiler setpoint temperature to 75ºC by default, and the installation flow temperature
can be adjusted to the selected setpoint temperature using the mixing valve.
The boiler setpoint temperature can be changed using the MODE touch button to browse to the
“
boiler temperature setpoint
" display option. When the display shows this option, touch the "+ /-"
symbols to select the desired temperature.
If you wish, the SRAM2/EV Underfloor Heating circuit function can be totally disabled, by selecting
"
OFF
" as the installation flow setpoint temperature.
NOTE: When the Underfloor Heating circuit function is disabled by selecting OFF as the setpoint
temperature, only circuit 1 will be disabled. Circuit 2 will continue to function.
