Standard communication
The communication icon is steadily lighted on if
communication with the heater is running properly.
Normally the requested heat output is displayed as
% of the nominal output.
Where applicable the number of heaters connected is
displayed on the top right.
Operation selection : Off - Summer - Winter
Press the [ ] button to select the operation mode
to be run: OFF ( ), SUMMER ( ) or WINTER ( ).
WINTER activates the heating.
Run and the output is modulated upon the outdoor and
room temperature (i.e. heating request from the chrono-
thermostat; the outdoor temperature is compared to
a set-point value).
SUMMER activates only the air blower for ventilation.
It can be activated manually or
automatically by program; T2 automatic; T0 and T1
in any other mode of operation and deactivating the
ventilation.
The manually activation - by pushing the bottom on
the chrono thermostat.
In the first case press the [FAN] button to run the air
blower and press it again to stop it.
Press [OFF] to put the heater on stand-by, from any
function mode.
Outdoor temperature
Press long the [ ] button to enter the outdoor
temperature setting menu.
If one of the appliances switched to Encrono GA1 has
an outdoor temperature probe (configured to translate
information via Open Therm) it is possible to visualize
the value closed to indicator "tou".
By which the set point "Tset" can be loaded and the
outdoor temperature displayed.
The Tset value is used to calculate the heat output
request and shall be within the range -99 / 100 °C.
Heater lockout and remote reset
In case of heater (or more than one) failure, which
causes the unit lockout, different signals might be
displayed based on the type of protocol/ application
used:
1. two digits number that identifies the faulty unit
(n. 01 ... n.02, ....etc), in case of heaters cascade
installation 2. "E00" error code, which identifies the
mode of failure
3. "Err" in case the mode of failure is not available
(generic error) Table xx shows the list of failure modes
and codes.
Note that E05 is the sole failure independent from the
number of units connected, as it refers to the room
temperature sensor that is fixed inside the control panel
indipendente of the display shown on the left side of
the screen, on the right you will see a funter three-digit
error code, preceded by the letter F, communicated
directly from the card remote and displayed without
any processing by the programmable thermostat.
Press [RESET] button to reset the alarm.
However some alarms cannot be reset by the control
panel; in this case E11 will be displayed for 10 s. For
some alarm the reset button is deactivated and a
"beep" sound advises that reset by the control panel
is not allowed.
