E20 REMOTE CONTROL (

E20 REMOTE CONTROL (OPTIONAL

OPTIONAL

OPTIONAL))))

A remote control (E20) may optionally be supplied together with the Minny 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 Nº1 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 Nº1,
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

(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.

The maximum temperature for heating circuit Nº1, 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.

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.

The maximum temperature, an operating curve for heating circuit Nº1 (see instructions enclosed
with the E20 remote control) and the desired heating times and room temperatures can all be
selected  on  the  remote  control.  The  E20  remote  control  calculates  the  required  boiler
temperature  at  each  particular  time,  depending  on  the  temperature  inside  the  home  and  the
outside  weather  conditions,  in  accordance  with  the  operating  curve  selected  (setting
HEATSLOPE  1  on  the  E20),  switching  the  heating  on  and  off  in  accordance  with  the  heating
times and the room temperatures programmed.

When the boiler is installed with a DHW production tank connected, the E20 remote control can be
used to select up to two DHW temperatures and the desired DHW production times. The E20
