 Switch off the power supply to the heating system, see
section 72.
 Open the boiler door as instructed in section 73.
 Remove the UBA 3 as instructed in section 82.
 Remove the cover from the connection tray, see section 114.
 Set the multimeter to "Measure resistance" [1].
 Check the electrical resistance of the connection between the
two black contacts (low-voltage connector pins 22 and 24) on
the UBA 3 mounting base [2]. The electrical resistance of this
connection must be approximately 0
Ω [2].
 Check the electrical resistance of the connection between the
two black contacts (low-voltage connector pins 50 and 78) on
the UBA 3 mounting base [2]. The electrical resistance of this
connection must be approximately 0
Ω [2].
 Install the lid on the connection tray in reverse order.
 Install the UBA 3 in reverse order of removal.
 Close the boiler door as instructed in section 77.

 Open the cover of the BC10 on the front of the boiler as
instructed in section 69.
 Remove the BC10 by depressing the lock on the left-hand
side.
 Switch on the power supply to the heating system, see
section 79.
 Put the main power switch on the control panel in position "1"
(On), see section 80.
 Set the multimeter to "Measure DC voltage".
 Check that there is between 7.8 and 15.2 VDC on both left-
hand contacts of the connector on the bottom plate of the
BC10.
 Install the BC10 in reverse order.
 Close the cover of the BC10 on the front of the boiler in
reverse order.
