Engine Preheat Pump Indicator Light: (HHE-200 Model Only)
This indicator light will illuminate GREEN whenever the Engine Preheat Pump
is operating. Please note that this light will only be active if the Engine Preheat
switch is
ON
in conjunction with either the Diesel and/or the Electric switch. If
this indicator light illuminates RED, it indicates an electrical overload condition
(i.e. short) has occurred in this particular component’s circuitry.
Heating Status Indicator Light:
This indicator light will illuminate GREEN whenever the Hydro-Hot’s VDC /
VAC Control Thermostat is calling for heat, allowing the water and antifreeze
solution in the Hydro-Hot’s Boiler Tank to be heated by either the Diesel-
Burner and/or the Electric Heating Element. When this indicator light is off, no
heat is being supplied to the Hydro-Hot’s Boiler Tank.
NOTE:
The Hydro-Hot’s VDC / VAC Control Thermostat will automatically
activate the Diesel-Burner and/or the Electric Heating Element,
only
if the
Diesel and/or Electric switch is in the
ON
position. So to heat your
motorhome / domestic hot water, simply choose the desired heat
source(s) and leave the switch(s) (i.e. Diesel and/or Electric)
ON
.

Electric Heating Element Status Indicator Light:
This indicator light will illuminate GREEN whenever the Hydro-Hot’s Electric
Heating Element is operating and providing heat to the Hydro-Hot’s Boiler
Tank. Please note that this light will only be active if the Electric switch is in
the
ON
position. If this indicator light illuminates RED, it indicates an electrical
overload condition (i.e. short) has occurred in the Electric Heating Element’s
VDC powered circuitry.
