3.6 Solar Charge Management
The EC601/602/651 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. The voltage and
current produced from the regulator can be viewed on the multi-function display by selecting the Solar
Power menu item. 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 Smart Charging
The EC651 PSU (Motorhome only) 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 EC620 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 system incorporates an automatic tank fill feature (Caravan only). When turned on this will
automatically fill the onboard water tank from the external container and will switch off automatically
when full. To enable tank fill, select ‘Tank-fill on’ on the control panel. To ensure the external pump is
not damaged if the external tank runs dry, the pump runs for a maximum of 7 minutes.
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
select 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
select 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 EC651 (Motorhome only) features the ability to switch on water tank heater to provide frost
protection for the fresh and waste tanks. The tank heater symbol is displayed on the control panel
when this feature is enabled. The tank heaters will only operate if there is over 25% in the relevant
water tank and the external temperature sensor detects that the temperature falls below 2 degrees C.
If the temperature rises above this level the heaters will be switched off but the feature will remain on.
If the tank heaters are turned on before starting a journey, when the engine is started the tank heaters
will remain on for the duration of the journey. When the engine is stopped the tank heaters will remain
on for a further 15 minutes. If the engine is restarted within this 15 minute period the tank heaters will
remain on, again for the duration of the journey.
When the engine is stopped the tank heaters will turn off after a 15 minute period. To turn them back
on you will need to turn the control panel on and then tank heaters on.
