Please read all instructions before proceeding.
The Share-a-Wire module is designed to be used with specific Braeburn
thermostats where a 24 VAC common wire is required but not enough wires are
available. The module uses the K terminal signal from the thermostat to operate
both the compressor and the system fan.
1 Installation
The Share-a-Wire module can be mounted on a wall, stud or on the equipment
itself. Mounting orientation and leveling are not important.
1. Remove cover of module by gently squeezing both ends and pulling cover off.
2. Using the base as a template, mark two mounting holes.
3. Using a small drill bit, drill two mounting holes.
4. Secure base with two provided screws.
5. After wiring is complete, reattach cover to the installed base.
2 Wiring
1. On the thermostat side of the module (FROM STAT) Connect the 24 VAC power
wire from the thermostat to the Rh terminal. NOTE: For 2 transformer systems,
connect both Rh and Rc and remove jumper.
2. Connect the 24 VAC common wire from the thermostat to the C terminal
on the module.
3. Connect the W (heat relay) wire from the thermostat to the W terminal

a heat pump system.
4. Connect the K wire from the thermostat to the K terminal on the module (do not
remove jumper).
