How to properly install a jumper to R&W terminals

What is the proper procedure when installing a jumper to R&W terminals?

What should be done to the R&W thermostat wire before installing a jumper?

Answer:

When installing a jumper to R&W, the R&W thermostat wire must be removed.

When installing a jumper to R&W, the R&W thermostat wire must be removed. This is because R&W are standard thermostat terminals used for controlling the heating system. By installing a jumper between R&W, you are bypassing the thermostat which means the heating system will be constantly ON, irrespective of the desired temperature. Removing the R&W thermostat wire ensures that the heating system is properly controlled by the jumper connection.

It is important to follow this procedure to ensure that the heating system functions correctly and is not overridden by the jumper connection.
