E20 Remote Control (Optional); Functioning Without An Outdoor Sensor; Functioning With An External Sensor (Optional) - Trianco TRO Evolution System Series Installation And Operating Instructions Manual

11.- E20 REMOTE CONTROL (OPTIONAL)

A remote control (E20) may optionally be supplied together with the TRO Evolution System
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.

11.1.- 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 SRHFC2/EV underfloor heating kit (mixed circuit)
If the boiler has an SRHFC2/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.

11.2.- 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.
