OPERATION
ELECTRIC
When the Water Heater is operating from the AC Power, water temperature in the
tank is regulated at 140 deg F (60 deg C). The thermostat is non-adjustable.
HEAT EXCHANGER
When the Water Heater is operating from the Heat Exchanger, water temperature in
the tank will approach the temperature of the engine coolant. If the Heater is equipped
with a Temperature Control Valve (TCV) the water temperature in the tank will be
regulated at approximately 140 deg F (60 deg C).
The Temperature Control Valve (TCV) regulates the flow of coolant through the Heat
Exchanger by sensing the output temperature of the water in the tank. As the output
water temperature rises, the thermal actuator closes the valve and restricts the coolant
flow through the Heat Exchanger limiting the water temperature to approximately 140
deg F (60 deg F) . When the output water temperature cools the valve opens and
allows engine coolant to flow through the heat exchanger.
