Installation; Step 1 - Thermostat Location - Bryant LEGACY T2-PAC Installation Instructions Manual

Power
All Legacy Series models are dual powered. They can operate from batteries or
24VAC power. Operation from 24VAC is preferred if available. Battery
operation is used when there are not enough wires to support 24VAC operation
or when "armchair programming" is desired. For an AC system, 5 wires are
needed for 24VAC operation and 4 wires for battery operation. For a HP system,
6 wires are needed for 24VAC operation and 5 wires are sufficient for battery
operation. For heat only operation with batteries, only 2 wires are required.
When battery operation is used, the C terminal does not need to be connected.
Provision is also made for separate heating and cooling transformers via separable
Rc and Rh terminals which are connected via a factory- -installed jumper wire.
