V.2.
Fire-up
This function enables the user to easily fire-up the CH boiler. After initiating the fire manually (preparing
the furnace and starting the fire), the user activates automatic fire-up phase in the controller menu. The
controller conducts the fire-up process maintaining the blow and gradually feeding fuel. Thanks to
optimum parameters, CH boiler smoothly switches to operation mode.
Once the CH boiler entered operation mode, instead of
Fire-up
function the menu displays
Damping
function, which may be used to activate damping process.
V.3.
Screen view
This function is used to choose between standard screen view and test screen view (secured with a code).
V.4.
Fuel tank full
This function should be used after the fuel tank has been fully filled, in order to reset the fuel consumption
percentage to 100% (the value displayed in the top right-hand corner of the main screen, below the
clock).
NOTE
:
Before using this function for the first time it is necessary to calibrate the fuel feeder operation
in the fitter’s menu.
V.5.
Temperature settings
V.5.a)
Pre-set CH temperature
This option is used to define the pre-set CH boiler temperature. The setting rage is 45⁰C do 80⁰C.
The pre-set temperature may also be changed with the use of weekly control function.
The pre-
set temperature is the sum of all these values but within the range of 45⁰C do 80⁰C.
V.5.b)
CH hysteresis
This option is used to set the hysteresis of the pre-set temperature. It is the difference between the
temperature of entering the sustain mode and the temperature of restoring operation mode (for example:
when the pre-set temperature is 60 ºC, the hysteresis is 3ºC, entering sustain mode takes place at the
temperature of 60 ºC whereas returning to the operation mode takes place at 57 ºC).
V.5.c)
Pre-set DHW temperature
This function is used to define the pre-set temperature of the domestic water (this function is inactive
when
house heating
mode is selected). This value may be adjusted directly from the main screen view.
After the tank water reaches this temperature, DHW pump is disabled. The pump will be enabled again
when the temperature drops below the pre-set temperature by a pre-defined value.
V.5.d)
DHW hysteresis
This option is used to set the hysteresis of the pre-set water tank temperature. It is the difference
between the pre-set temperature (desired temp. of the water tank when DHW pump is switched off) and
the temperature at which DHW pump is activated again (for example: when the pre-set temperature is
55 ºC, the hysteresis is 5ºC, DHW pump is switched off and CH pump is enabled when the pre-set
temperature of 55 ºC is reached. DHW pump is activated again when the temperature drops to 50 ºC).
V.5.e)
Temperature of pump activation
This option is used to define the temperature of CH pump and DHW pump activation (temperature
measured on the CH boiler). Below this temperature value both pumps remain inactive whereas above
this value the pumps are enabled and operate according to the operation mode (see: pump operation
modes).
