Unitherm Governor
Tech Tip: Test a U.G by placing it in a bowl of
hot water (water temp 120ºF / 49ºC or higher). If
working properly, it will open as it warms up.
*NOTE: Do NOT heat U.G. using open flame.
The UNITHERM GOVERNOR helps prevent condensation and scale. It is a thermostatic
mixing valve used to control and regulate the water temperature in the heat exchanger.
Low temperatures in the exchanger can cause condensation.
This indicates that the heat exchanger is running cool. This may be caused by too much
flow. Make sure the pump is not supplying more than 100GPM. Adjust flow accordingly.
Also check the U.G. to make sure it is working properly and not damaged from chemical
corrosion or stuck.
