Single channel standard
relay wiring:
The default switch position on the Receiver is
relay mode (position 2). Use the diagram to
wire the system.
NOTE: Remove any existing controls or
programmers and ensure pre-existing wires or
connections are made safe.
NOTE: If installing in OpenTherm mode, ensure
you use separate cables for the low/high voltage
connections. These should not share the same
shrouding.

OpenTherm wiring:
Move the switch to position 1 to put the
Receiver in OpenTherm mode. Do this before
using the diagram to wire the system.
