Electronic Climate Control

PRODUCT DESCRIPTION

The ELECTRONIC CLIMATE CONTROL (ECC) System offers automatic and manual control of the front and
rear roof-top air conditioners and furnace/s in the motorhome. The system includes an energy management
system that shuts off the air conditioners when necessary to prevent electrical over load. It also includes a
number of features that provide the owner with the most comfortable temperature controlled environment
possible.
In the HEAT mode the system offers automatic control of the furnace/s in a manner identical to standard wall
mount thermostats.
In either the LOW COOL or HIGH COOL modes the air conditioner fans run continuously at the selected speed
and the compressors are controlled to maintain the set point temperature. When in the AUTO mode, the unit
automatically controls the compressors and selects the appropriate air conditioner fan speed based on the
difference between the set point temperature and the ambient temperature in the motorhome.
In addition to controlling the temperature within the coach, the system constantly monitors the current being
drawn by all of the 120 VAC electrical appliances, including the air conditioners, and will control the operation
of the air conditioners to prevent them from over-loading the circuit breakers. Once the system turns the air
conditioners off, it will keep them off until there is enough power available to restore normal operation.
The system has been designed to operate from 120 VAC, 30 Amp service only . Connecting the coach to any
other power source will cause the system to operate improperly. If only 20 Amp service is available, "load
management" must be done manually by the owner, and only one air conditioner can be operated at a time,
unless the auxiliary generator is utilized.
