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, connect the jumper to 24 V. For systems that switch the neutral supply to
the heating commands, connect the jumper to COM.
2. The common terminals are connected and can be used for all inputs, outputs, and 24 VAC power.
