SECTION 6: TROUBLESHOOTING
The Aqua-Hot will automatically restart once the electrical overload (i.e., short)
and/or high heat condition is corrected.
Heating Zones Status Indicator Lights:
These five indicator lights (separately) will illuminate GREEN whenever a
Zone Thermostat, for each particular zone, is calling for heat. The GREEN
indicator lights also indicate that VDC power is being supplied to the particular
interior heating zone’s Heat Exchangers (i.e., fan motors). If any of the five
indicator lights illuminate RED, it indicates that an electrical overload condition
(i.e., short) has occurred in a particular heating zone’s circuitry.
NOTE:
A short in either a heating zone’s Interior Room Thermostat or
heating zone’s Heat Exchanger circuit will cause the indicator light to
illuminate RED.
Pumps #1, #2, and #3 Indicator Lights:
These indicator lights (separately) will illuminate GREEN whenever a
Circulation Pump is operating. If any of the three indicator lights illuminate
RED, it indicates that an electrical overload condition (i.e., short) has occurred
in the particular component’s circuitry.
NOTE:
The Zone Circulation Pumps (separately) are activated whenever
a Zone Thermostat calls for heat.

The Aqua-Hot is off due to a combination of high electrical VDC power
loads and a high surface temperature of the Electronic Controller.

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 Aqua-Hot’s VDC / VAC
Control Thermostat is calling for heat, allowing the water and antifreeze
solution in the Aqua-Hot’s Boiler Tank to be heated by either the Diesel-Burner
and/or the Electric Heating Element(s). When this indicator light is off, no
heat is being supplied to the Aqua-Hot’s Boiler Tank.
NOTE:
The Aqua-Hot’s VDC / VAC Control Thermostat will automatically
activate the Diesel-Burner and/or the Electric Heating Element(s),
only
if
the Diesel and/or Electric switch is in the
ON
position. In order 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 Aqua-Hot’s Electric
Heating Element(s) is operating and providing heat to the Aqua-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.
