Activation of the TEST mode
Press heating buttons together for 5 seconds to activate the
TEST
mode (see 3 and 4 - pics.1 and 2). Boiler
is started by maximum output of the set heating and actual value, as it is given in the text below.
Signs of heating and DHW flicker on display and temperature of heating. Values of actual heating output
and actual value of flame flow (uA x 10) are also displayed.
To exit TEST mode, repeat same process as by activation. TEST mode is everytime automatically
stopped after 15 minutes.
Regulation of heating output
To make regulation of heating output, set boiler into the TEST mode. Press buttons of heating (see 3 and
4, pics. 1 and 2) to increase or to decrease output (Minimum = 00 - Maximum = 100). If the RESET button
is pressed for 5 seconds, maximum output stays at the level that was actually set.Exit TEST mode.
Operation start-up
Before start and after all installation actions that required disconnection from distribution network or
works on safety mechanisms or boiler parts, it is necessary to check the following:
Before boiler start
- open eventual control valves installed between boiler and distribution network.
- check tightness of connections, if there is no gas leakage; be carefull and use soap water solution
- check pressure of expanse vessel overfill
- fill hydraulic devices and ensure absolute deareation of boiler and heating system - open deareation
valve on boiler, eventually deareation valves of distribution system
- check pressure in heating system, cca 1bar. in cold state
- fill outlet syphone and check correct connection to outlet device for condense water
- check, if there is no water leakage in the heating system, DHW circuit, connections or in the boiler
- check accuracy of connection of electrical device and functionality of grounding
- check if pressure value and gas overflow for heating are adequate to requirements
- check, if there are no flammable liquids or other materials in near surrounding of boiler
Checking during operation
- Turn device on
- Check tightness of gas circuit and heating system
- Check tightness of chimney and air-flue gas exhausts during boiler operation
- Check correct tightness and functionality of syphone and device of outlet of condensed water
- Check correct water circulation between boiler and heating system
- Check correct modulation of gas valve by heating and also by DHW preparation
- Check correct boiler start by several tests of start and stop by room thermostat or by remote time
controller
Use combustion analyser, connected to the flue gas outlet from the boiler to check, if the CO2 content in
flue gas - by max. and min. boiler output - is adequate to the supposed content given in the table with
technical data for appropriate gas sort, eventually adjust it , as it is given in the instructions in chapter
about CO2 adjustment on page 18.
-Check, if fuel consumtion, displayed on counter, is appropriate to consumption given in the table with
technical data.
- Check correct parameter programming and make eventual adjustments according to your needs
(compensation curve, output, temperatures, etc.)
