1.

RH needs to be connected for W1 and W2 to energize. For heating systems with an isolated power
supply, connect RH to the R terminal of the heating system. For systems that switch the hot supply
to the heating commands, jumper to 24 V. For systems that switch the neutral supply to the heating
commands, jumper to COM.

2.

The common terminals, which do not include NET COM, are internally connected and can be used
for all inputs and outputs.
