I am looking to interlock a new ERV to the existing air handler. The wiring diagram from the ERV manual is included below.
My question concerns how to splice together (is this the correct term for it?) the wires shown in the highlighted area. What I'm currently planning (for each of the wires, red and green):
- Cut a short wire "stub"
- Twist together the copper ends of the wires from the ERV, the thermostat and the stub wires and put a wire nut over the connection
- Run the stub wire to the air handler board
Is this the correct approach (located in the US)?
For reference the ERV is a Panasonic FV-10VEC2, the air handler is a Carrier 40MBAAQ24XA3 and the thermostat is an Ecobee 5.
