II.l) Information about the programme
This function allows the user to check the controller programme version.
III. Installation menu
The functions of the installation menu should be set by the person installing the boiler or service
personnel of the manufacturer.
III.a) Fan coefficient
This function is used to adjust the fan power. If the blow force is too low/high, the coefficient
should be adequately increased/decreased in order to ensure efficiency.
The most common cause of inadequate fan operation is the considerable difference in voltage
supply for different recipients which has a significant impact on the fan functioning.
III.b) CH boiler power coefficient
CH boiler power coefficient serves to optimize the feeder operation so that it supplies an
appropriate amount of fuel. With this function the user may increase or decrease the amount
of fuel fed to the CH boiler (the amount is given in percentages).
After the CH boiler power is defined initially in the main menu, the CH boiler coefficient
enables the user to choose precisely the optimum amount of fuel, on the basis of the calorific
value of a given fuel type.
III.c) Room regulator
A room controller can be connected to ST-480 controller. This function allows to configure the
controller by selecting “ON” option. Additionally, the user may check the programme version of
the room controller.
After connection of TECH controller the user may check and change the preset
temperature of the central heating system, hot domestic water and the mixing valve.
Additionally all boiler controller alarms are displayed. When the operation involves the mixing
valve the user may preview the current external temperature while viewing the main screen
with the valve parameters .
After TECH Controller option is enabled a letter "P" appears in the upper part of the
display in the main screen of the controller. A flashing letter "P" indicates that the temperature
in the room is too low. As soon as the required room temperature is reached the letter "P" stops
flashing and stays on.
ATTENTION: No external voltage can be connected to the room controller output.
