How to wire up Wiser Air on a 2 wire heating system?
Wiser Air. Resolution:
Wiser Air is designed for 24 Vac circuits ONLY. When applying it on a two wire application, with wires labeled R and W, a common wire is required. This can be achieved by running a new wire making an common connection between the control board and thermostat. The wire extender that is included in the box with Wiser Air will not work on this type of application. Professional assistance may be required.
