2.0 INSTALLATION
2.3 COMMISSIONING
Once the system is fi nally fi lled turn down
the servicing valve for the ballvalve in
the F & E cistern to the point where the
warning/overfl ow will cope with the discharge
arising from a ballvalve failure.
Cleansing Hot/Cold Water System Treatment
Fully fl ush and if necessary chlorinate the hot
and cold water system in accordance with the
recommendations in the Model Water Byelaws
and BS 6700.
Commissioning the BoilerMate Control
System
For maximum system efficiency the store
thermostat must be in control of the boiler i.e.
the boiler cycles on the store thermostat and
not on its integral thermostat.
The BoilerMate control system will automatically
commission itself to match the ac tual
performance of the installed boiler.
The control system/A.C.B has been initialised at
the factory and will operate automatically.
However, the operation of the control system
should be checked as follows on the A.C.B
(shown opposite).
1. Set the boiler thermostat to MAXIMUM
2. Switch off heating on the clock/
programmer and room thermostat
3. Switch off hot water on the programmer
if 2 channel clock is fi tted
4. Check the jumper settings are
correct. These must all be in the
correct positions for the appliance to
work correctly i.e. fi tted on terminals
1, 3 and 4.
5. Switch on the mains supply.
The A.C.B. will automatically commission
itself to suit the system/boiler and the dot
after the ON the display will fl ash
e.g.
The control system is now initialised. The
operation of the controls can now be checked.
1. Horizontal LED bar 2 'store' will be lit.
Boiler and boiler pump will be running and
green LED's 1 and 2 on the A.C.B will be
switched on.
