E20 REMOTE CONTROL (OPTIONAL)
A remote control (E20) may optionally be supplied together with the
Evolution EV HFC
boiler. This
remote control can be used to fully operate the boiler from any room in the home it is installed in. The
E20 remote control governs the settings of heating circuit 1 and the installation’s domestic hot water
production (where the case may be).
This remote control allows the hours of home comfort to be programmed for heating circuit 1,
adjusting the installation to the particular requirements of the home by measuring the room
temperature and consequently adapting the installation temperature. The remote control can also be
used to adjust the DHW and heating setpoint temperatures at any time, and for viewing the different
boiler operation settings. It also warns of any functioning anomalies affecting the boiler.
The E20 remote control may optionally be connected to an external sensor, for measuring the outside
temperature. When this option is installed, the remote control can adjust the home comfort level
(circuit 1) according to the weather conditions at each particular time, optimising fuel consumption
and heating comfort in the home.
The E20 remote control takes over the control of the boiler when it is connected to it. The different
selectable boiler temperatures must be modified using the remote control. It is easy to install, only
requiring 2 wires for communication between the boiler and the E20 control. It is connected to the
boiler by connecting the two wires on terminal strip
J4
(see “Electrical Connection Diagram”). For
correct installation and functioning, carefully read the instructions enclosed with the remote control.
The following sections contain a general explanation of the E20 remote control’s different operating
modes and options.
10.1
Functioning without an outdoor sensor
Conventional heating installation (direct circuit)
The maximum temperature for heating circuit 1, the scheduled heating times and the desired
room temperatures can be selected on the remote control. The E20 remote control will calculate
the boiler temperature required at each particular time, depending on the temperature of the
room, and it will activate or disable the heating mode of circuit 1 depending on the heating
times and room temperatures programmed.
Heating installation with an SRFC2/EV underfloor heating kit (mixed circuit)
If the boiler has an SRFC2/EV Underfloor Heating Kit installed on circuit 1, the underfloor heating
circuit is adjusted and controlled from the boiler control panel (see "
Functioning with an
underfloor heating kit
").
The E20 remote control can be used to programme the desired heating times and room
temperatures.
10.2
Functioning with an external sensor (Optional)
If the E20 remote control is fitted with an outdoor temperature sensor, it can calculate the heating
temperature of heating circuit 1 according to the outside weather conditions at each particular
time, with optimum adjustment of the heating installation conditions for improved comfort in the
home and energy savings.
