How To Bypass Aquastat

Aquastats are used in heating systems to maintain a desired water temperature. When the water temperature falls below the aquastat set point, the aquastat activates the heating system to bring the water temperature back up to the set point. If there is a problem with the aquastat, such as a faulty wiring connection, the heating system will not activate when it should, resulting in an overheated or frozen water tank. Bypassing the aquastat allows the heating system

How To Bypass Aquastat

Aquastats are devices used to maintain a set water temperature in a heating system. If the water temperature falls below the set point, the aquastat will activate the heating system to return the water to the set point. If there is a problem with the aquastat, or if someone wants to override the set point, it is possible to bypass the aquastat. To bypass an aquastat, one must first locate the aquastat. The aquast

  • ) open the panel located on the front of the aquastat. 2) locate the jumper wire. the jumper wire will be a small, silver
  • Colored wire that is connected to two terminals. 3) disconnect

on troubleshooting -If the boiler is not firing, check to see if the aquastat is calling for heat by testing the voltage at the aquastat. -If the voltage is present, then the aquastat may be faulty and need to be replaced. -If the voltage is not present, then there may be a problem with the wiring or with the boiler itself.

Frequently Asked Questions

How Do You Know If Aquastat Is Bad?

The aquastat is a thermostat that is used to maintain a constant water temperature in a boiler. If the aquastat is bad, the water temperature will not be maintained, and the boiler may overheat.

How Do You Reset Aquastat?
