Honeywell Aquastat Jumping Troubleshooting

There are steps you can take to remedy a Honeywell Aquastat.

The Honeywell Aquastat is effectively the control panel for the heating of your home if you have a system which is set up by the Honeywell company. It ensures that you have the correct temperature of water, the right amount and a reliable timing system -- assuming the unit is working correctly. There may come a time when you have to troubleshoot some issues which could impede the normal working of the Honeywell Aquastat.

Instructions

1. Turn the "Low" differential knob to 170 degrees Fahrenheit if you are finding that the water temperature is too hot coming from the water heater. This will limit how hot the water coming from the heater can get.

2. Similarly, turn the "High" differential knob to 190 degrees Fahrenheit if the water temperature is too cold. This is the hottest temperature possible and will ensure exceedingly hot water; indeed, this setting should be used with caution.

3. Turn the "Auto-Manual" switch to "Auto" if the hot water heating is running constantly, against your wishes. This will cease the constant operation, and ensure that it is only activated based on the settings of the thermostat.

4. Set the "Differential" knob to 15 degrees Fahrenheit to avoid the temperatures coming from the Honeywell Aquastat varying widely. This will ensure a reasonably consistent level of heating, never more than 15 degrees hotter or colder than the optimum temperature.
