Hot Water
When the Hot Water icon is selected the system will cycle
and maintain the hot water heat exchanger so hot water is
available on demand. Note: In order for hot water to be main-
tained, either the burner or the electric element icons
must be selected (or both).
Electrical Element
When the 120V Electric Element icon is selected the 1500
watt 120V element will activate and provide supplemental
heat to the coolant.
When both the Burner and Element icons are selected
the system automatically prioritizes using heat from the elec-
tric element. If there is greater heating demand on the system
the burner will automatically engage and heat the glycol.
