Instructions for the user
1.14.11 Operation with external probe (optional)
Boiler can be connected to a probe measuring the external temperature (optional - not compulsory, supplied by the manufacturer).
Once the external temperature value is known, the boiler will automatically adjust the heating water temperature: increasing it as the
external temperature decreases and decreasing it as the external temperature increases. This will both improve room comfort and reduce fuel
consumption. The maximum temperature is respected all the same.
This boiler operating mode is called "sliding temperature operation".
Heating water temperature varies based on a programme written inside boiler electronic microprocessor.
When working with an external probe, the
CH +/-
buttons are no longer used to set heating water temperature, but to edit ictitious ambient
temperature, namely the desired theoretical temperature.
During temperature setting, the ictitious ambient temperature
symbol lashes on the display and the value being set is shown.
For optimal curve adjustment, a position close to +20 °C is recommended.
For further details on "cruising temperature operation", refer to paragraph
Installation of the (optional) external probe and sliding temperature
operation
on page
57
.
WARNING
Only original external temperature probes supplied by the manufacturer must be used.
The use of non-original external probes, not supplied by the manufacturer, may affect the operation of the external probe itself
and of the boiler.
1.14.12 Operation with (optional) remote control
The boiler can also be connected to a Remote Control (optional - not compulsory, supplied by the manufacturer) so as to manage several
boiler parameters, such as:
•
boiler status selection.
•
ambient temperature selection.
•
CH system water temperature selection.
•
DHW temperature selection.
•
CH system or heater activation times programming.
•
boiler diagnostics display.
•
boiler reset and other parameters.
To connect the Remote Control, see
Installation and operation with Open Therm Remote Control (optional)
on page
56
.
WARNING
Only use original Remote Control Units supplied by the manufacturer.
The use of non-original remote controls, not supplied by the manufacturer, may affect Remote Control and boiler operation.
1.15 Boiler shut-down
The boiler shuts down automatically if a malfunction occurs (see
Interpreting boiler status from display indications
on page
13
).
To determine the possible causes of malfunction, see
Troubleshooting
on page
90
.
Below is a list of shut-down types and the procedure to follow in each case.
