2.3 Zone Thermostat(s) Operation
Interior Room Thermostats
Simply adjust each Room Thermostat to the desired temperature. Then
whenever a Room Thermostat “calls-for-heat” the Hydro-Hot’s
Circulation Pump(s) and Interior Zone Fans will be activated. These
devices together will supply warmth and comfort to each interior heating
zone. Please contact your specific motorhome manufacturer for the exact
room thermostat location(s).
NOTE: Interior zone heating and bay heating will not operate if the Hydro-
Hot’s water and antifreeze solution is cold or if domestic hot water is being
used on a continuous basis (i.e. during showers).
Bay Thermostat
Simply adjust the Bay Thermostat to approximately 40 degrees
Fahrenheit. This will prevent freezing of the domestic water storage
system. Please contact your specific motorhome manufacturer for the
exact Bay Thermostat location.

NOTE: Both the Diesel Burner and the 120 VAC Electric Heating Element
are thermostatically controlled. Either, or both, heating sources will
automatically maintain the temperature of the Hydro-Hot's water and
antifreeze solution between approximately 160-190 degrees Fahrenheit.
So simply choose how you want to heat your coach/hot water and just
leave the Switch(s) (Diesel, Electric, or both) ON.

2.4 Using the Domestic Hot Water System
When the Hydro-Hot is at operating temperature, the domestic water is
automatically heated as it is being used. Because the Hydro-Hot does not
store any hot water simply open any hot water faucet and a continuous
supply of domestic hot water will be present within a few seconds. This hot
water feature is continuous and is accomplished by the Hydro-Hot’s Mixer
Valve and Intergal Domestic Hot Water System. Please note that the
“Diesel” Control Switch must be ON to get an unlimited supply of hot water
(i.e. during showers).
