E20 REMOTE CONTROL (OPTIONAL)
A remote control (E20) can optionally be supplied together with the Evolution Solar HFD boiler. This
remote control can be used to fully operate the boiler from anywhere in the room in which it is
installed. The E20 remote control governs the parameters of heating circuit Nº 1 and the installation’s
domestic hot water production
This remote control allows the hours of home comfort to be programmed for heating circuit Nº 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 hot water and heating set point temperatures at any time, and for viewing the
different boiler operation parameters. 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. With this option installed, the remote control can adjust the home comfort level circuit
Nº 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 different operating modes and options of
the E20 remote control.
13.1
Functioning without an outdoor sensor
Conventional heating installation (direct circuit)
The maximum temperature for heating circuit Nº 1, the 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 Nº 1 depending on the heating times
and room temperatures programmed.
Installing heating with an SRS2/EV underfloor heating kit (mixed circuit)
If the boiler is supplied with an integrated SRS2/EV underfloor heating kit, underfloor heating
circuit Nº 1 is adjusted and controlled via the boiler control panel (see "operation with underfloor
heating kit").
The E20 remote control can be used to programme the desired heating times and room
temperatures.
