WARNING
!
When extending wire there is the possibility of
exposure to electromagnetic interference. Avoid
running wires beside or near high voltage 120/240
VAC conductors. If proximity to high voltage
conductors cannot be avoided, use stranded, twisted
pair of shield design wire. Ensure that only one end of
the shielding is grounded.
1. Refer to boiler manual and remove cover from
boiler and set aside.
2. Locate the wiring harness with the 6 pole
terminal block attached.
3. Locate the wire marker denoting terminal 1.
4. If the outdoor temperature sensor has not
been previously installed, the outdoor
temperature sensor can be wired to one of
two locations. It can be wired to the 6 pole
connector from the boiler or directly to the
Versatronik Como OT. If wiring to the Como
wall mounting plate, connect to terminals 5
and 6.
Refer to previous pages regarding the
mounting of the outdoor temperature sensor.
5. Connect Versatronik Como OT to terminals 1
and 2 of the 6 pole termination block from the
Vitodens 100-W, WB1B.
6. Terminate the OT communication wires at the
sub-base of the Versatronik Como OT.
Connect wires to terminals 1 and 2. These
wires are not polarity sensitive.
