Evolution EV HFC

8.2

Functioning with a Sanit hot water tank

The

Evolution EV HFC

boiler may be installed together with a hot water tank from the

DOMUSA

TEKNIK

Sanit

range, to obtain domestic hot water. For correct installation of the tank, carefully

follow the instructions given in the “Installation Instructions” section of this manual.

In this mode, select the desired DHW setpoint temperature (see "

Selecting the DHW setpoint

temperature

"). The burner and the DHW pump will switch on. When the hot water tank reaches the

selected DHW setpoint temperature, it is ready to heat up the heating installation if it is enabled,

starting up the heating pump and switching off the DHW pump. The burner will shut down when

the boiler reaches its selected setpoint temperature. The heating pump will stop when the room

temperature reaches or exceeds the temperature set on the installation’s room thermostat (if it has

one).

If you wish, you may totally disable the domestic hot water production function by selecting "

OFF

as the DHW setpoint temperature.

8.3

Heating circuit 2 functioning (Optional)

All the models in the

Evolution EV HFC

range of boilers have the option of controlling a second

heating circuit. This requires the installation of a second circulation pump on the boiler. To correctly

install this pump, carefully follow the instructions given in the “Installing heating circuit 2” section

of this manual.

Heating circuit 2 will work with the selected boiler setpoint temperature (see “

Selecting the boiler

setpoint temperature

” ) and the temperature of room thermostat 2 (

TA2

) (if the boiler has one). The

burner and the heating pump of circuit 2 (

) will begin to function until the installation reaches

the selected boiler setpoint temperature (or the temperature on room thermostat 2, if the unit has

one). When the temperature of the installation drops below the selected boiler temperature, the

burner will start up again, running the heating cycle.

NOTE: When the heating function is disabled, if OFF is selected circuit 2 will also be disabled.

8.4

Functioning with an SRFC2/EV Underfloor Heating Kit (Optional)

The

Evolution EV HFC

boiler may be used with an SRFC2/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 SRFC2/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.
