5. Commissioning
5.1. Central heating system check
Check for pressure in the system, it should be from 1.2 to 1.5 bar when the system is cold.
Vent all heating elements and installation.
5.2. Preliminary electrical check
For single phase system:
Check if power cable is tightened on RCCB (RCD) terminals
Check the presence of phase on RCCB (RCD) input terminals inside boiler
Measure exact voltage between L and N lines, if it is10% higher than nominal voltage
on the appliance, the appliance itself can be damaged.
For three phase system:
Check if power cable is tightened on RCCB (RCD) terminals
Check the presence of each phase on RCCB (RCD) input terminals inside boiler
Measure exact voltage between L1 – L2, L1 – L3, L2 – L3, L1 –N. If there is no
voltage between any combinations of phases one phase is missing and the heating
elements inside the appliance can be damaged. If the voltage between phases is
10% higher than nominal voltage of the appliance, the appliance itself can be
damaged
For all systems:
Check if fixed wiring system is used and that MCB is installed, and conform to chapter
2.2. or 2.3.
Check if the used power cable conforms to chapter 2.2 or 2.3
Test the RCCB (RCD) switch by pressing T button on it
Test the overheating system as described in appendix 9
5.3. Changing the speed of pump for central heating
For Termo Blok and Termo Blok PTV: open the cover of boiler as described in chapter 4.4. and locate
the central heating pump; use chapter 2.4. for assistance. Move speed slider (1) to desired mark. For
Termo Extra boilers an external pump is fitted, so consult the pump manuals for guidance.
