3.6 Solar Charge Management
The EC700 PSU incorporates a built-in solar charge management feature, which will monitor the input
from a separate solar panel and regulator. The Solar Active symbol will be displayed on the control
panel when there is an amount of energy available to charge the battery. In a motorhome, depending
on the charge state of the batteries, the solar power will be directed to the required battery and
continuously monitored to ensure optimum operation.
3.7 Mains Charging
The EC700 PSU incorporates a smart charge feature, which monitors both leisure and vehicle batteries
and automatically adjusts and directs the charger power (and solar power if a solar panel is installed) to
maintain the leisure and vehicle batteries at an optimal level.
3.8 Water Pump Operation
The EC700 control panel pump button operates the internal water pump drawing water from an internal
tank if fitted, or an external container when no internal tank is fitted.
The water tanks (fresh & waste) incorporate a level warning feature to warn the user when the fresh
water level drops below 25% or when the waste water level reaches 100%.
If the water pump power is turned on and the fresh water level drops to below 25% a warning beep will
be heard and a message will be displayed on the control panel. To cancel the warning, press the ok
button.
If the water pump power is turned on and the waste water level rises to full (100%) a warning beep will
be heard and a message will be displayed on the control panel. To cancel the warning, press the ok
button.
These warnings will not be repeated unless the water pump power switch is turned off and on again.
This is to ensure the warning does not become a nuisance.
3.9 Water Tank Heaters (frost protection) Operation
The EC700 features the ability to switch on water tank heater to provide frost protection for the fresh and
waste tanks. The tank heater symbol on the power settings screen of control panel is lit up blue when
this feature is enabled. The tank heaters will only operate if there is over 25% in the relevant water tank
