Functioning without an external sensor
Conventional heating installation (direct circuit)
The maximum temperature for the heating circuit, hours of heating and room temperatures
desired can be selected on the remote control. The E20 will calculate the boiler temperature
necessary at each particular time, depending on the temperature inside the home, and it will
switch the heating on and off according to the heating times and room temperatures
programmed.
Installing heating with an underfloor heating kit SRAC2/EV (mixed circuit)
If the boiler has an underfloor heating kit SRAC2/EV installed, the adjustment and control of the
underfloor heating is made 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.
10.2
Functioning with an external sensor (Optional)
If an external temperature sensor is connected to the E20 remote control, the E20 can calculate the
heating installation mode temperature in accordance with the outside weather conditions at each
particular time, with optimum adjustment of the heating installation conditions for increased home
comfort and energy savings.
Conventional heating installation (direct circuit)
The maximum temperature and an operating curve for the heating circuit, the heating times and
the room temperatures desired can be selected on the remote control (see instructions enclosed
with the E20 remote control). The E20 will calculate the boiler temperature necessary at each
particular time, depending on the temperature inside the home and the weather conditions
outside, in accordance with the operating curve selected (parameter CURVE 1 on the E20),
switching the heating on and off in accordance with the heating times and the room
temperatures programmed.
Installing heating with the underfloor heating kit SRAC2/EV (mixed circuit)
If the boiler has an underfloor heating kit SRAC2/EV installed and the control of this circuit is
activated on the E20 remote control, using the parameter CURVE 2 (see instructions enclosed
with the E20 remote control), the adjustment and control of the underfloor heating circuit flow
temperature will be performed by the remote control. The E20 will calculate the flow
temperature necessary at each particular time, depending on the temperature inside and
outside the home, in accordance with the operating curve selected (parameter CURVE 2 on the
E20 remote control). For mixed underfloor heating circuits, we recommend selecting operating
curves of under 0.8.
The boiler set point temperature will be fixed at 75 ºC and may be changed via the boiler control
panel. To change this setting, browse with the set button until the option
“tc”
appears on the
display. When it appears, press the set button and hold it down for 5 seconds until the
"tc"
symbol begins to flash. If the set button is pressed successively, the boiler set point temperature
will gradually increase. When the desired temperature has been selected, press the set button
and hold it down for 5 seconds again until it stops flashing. The value selected will be stored in
the memory.
The E20 remote control can also be used to selected the maximum heating circuit flow
temperature and programme the desired heating times and room temperature. The E20 remote
control will switch the heating on and off according to the heating times and room
temperatures programmed.
