OMMISSIONING
Commissioning the Space Heating
• The central heating is best commissioned when the store is hot and therefore
should be carried out after commissioning the BoilerMate A-Class OV SOL/Primary
system.
• Set channel 2 of the digital clock to continuous operation mode and ensure that
the room thermostat is calling for heat. This will be indicated by display segments
V1.3 and V1.4 being on respectively. The BoilerMate A-Class OV SOL controller
will now turn on the central heating pump and this will be indicated by display
segment H2.2 being lit.
• The boiler will switch on to achieve/maintain the temperature in the heating circuit
which will be indicated by V2.1 and H2.3 being lit.
• Wait until the heating circuit has reached its normal temperature before balancing
the system in the usual way to achieve a temperature drop of about 10°C.
• Set channel 2 of the digital clock and room thermostat as per manufacturer’s
instructions supplied and ensure that the digital clock instructions along with the
user instructions for the appliance are left with the user.
Commissioning the Domestic Hot Water System
• When the store is fully up to temperature, open a hot water tap nearest to the
appliance at approximately 10 litres/minute. After about 2 – 3 seconds, the plate
heat exchanger pump will start. This is indicated on the A.C.B. by display segment
H2.1.
• The hot water flow temperature should settle at about 52°C. Close this tap and
open the hot bath tap at maximum flow rate and record the flow rate and the hot
water temperature in the ‘Benchmark’ logbook.
• Close the hot water tap(s) and after few seconds, the plate heat exchanger pump
will stop running and display segment H2.1 will turn off.
