OPERATION
The Evolution EV HFM boiler is designed to heat a heating installation and provide instantaneous
domestic hot water. Optionally, an Underfloor Heating Kit (SRFM2/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
) or remote control
E20
(if the boiler is equipped with these). 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.
12.2
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 HFM
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.
