What is the default HVAC partner address for the e7w thermostat?

The default e7w partner address is 13, and the default HVAC partner address (such as X47 or similar) is 14. The e7w attempts to communicate with its HVAC partner assuming this address. If your HVAC partner uses a different address, you can change the partner address (PA) through Service Mode by selecting the PA parameter and using the UP/DOWN arrow buttons to set the desired address.
