Hydro-Hot Heating System (Optional)
The Allegro Bus may be equipped with an optional Hydro-Hot heating system (Figure 11-16) that provides a
continuous, on-demand supply of domestic hot water, as interior zone heating where and when it is needed.
Both heating features are accomplished by a unique VDC-Powered
Diesel-Fired Burner and a VAC-Powered Electric Heating Element
(120 VAC). These two heating sources maintain the temperature of the
Hydro-Hot’s solution of water and antifreeze.
To activate the optional Hydro-Hot heating system, the hydro-hot
switch (labeled “diesel burner switch”) located in the side cabinet
above the driver’s seat must be activated. By activating this switch, a
supply of hot water as well as interior heat can be provided. The
heating feature will be controlled by the thermostat mounted on the
wall. It is operated off the furnace function of the thermostat to
provide interior heat. Hot water will be supplied instantaneously and
continuously at any time the diesel burner switch is activated.
If interior heat and hot water are demanded from the Hydro-Hot
system at the same time, hot water will simultaneously take
precedence over interior heat; therefore causing the interior heat to
shut down and turn off until the water flow is turned off from water
sources.
Also featured in the Hydro-Hot system is an electrical burner switch.
With this switch activated and shore power available, it will supply a
very limited amount of hot water and limited interior heat.
The surge tank (Figure 11-17), located in the basement, should be
routinely inspected to make sure the antifreeze fill line stays in the
acceptable zone. If the antifreeze becomes low, you must add the recommended antifreeze stated in the Hydro-
Hot’s owner’s manual. If antifreeze is totally depleted from the
surge tank, a switch will be released inside the main Hydro-Hot
tank disabling the system from operating. Antifreeze will then have
to be added to the tank to rectivate the switch and allow the
system to operate.
If batteries accidentally become discharged and the Hydro-Hot
system is activated, the system will automatically shut down before
batteries are totally discharged. Once power is restored to batteries,
the system must be reset on outside control board (Figure 11-17).
For detailed instructions on operating the Hydro-Hot Heating system,
refer to the specific owner’s manual found in the Owner’s Information
Package.
