Hi, HELP, required.  As you are probably aware I’m new to caravaning, started only last year, we have a Lunar Clubman SR, 2017 which is fitted with the Sargent EC500 psu, it also has a control panel above the door. We also have the Aldi hot water / heating system. I’m trying to establish what if any thing the PSU unit does? So I’ll try and explain my problems one at a time, first issue we are connected to the mains power supply, we also have gas connected, on the main EC500 control unit located under the seat it has four lights the first two = Reverse Polarity and Charging I understand, however the next two Space heater and Water Heater are a mystery, because it appears the Aldi system provides hot water and heating, 1st question. Does the Space Heater button and the Water Heater buttons need to be on at all if we are using gas to provide hot water and heating via the Aldi system? 2nd question if I turn these buttons off will it have an adverse affect on the vans electrical systems, 3rd question, if they’re left on do they use power from the mains and 4th and final question at this point is “if the Aldi system provides hot water and heating from gas and electricity why have the EC500 fitted?.  YOUR HELP WITH THIS MATTER WOULD BE SINCERELY APPRECIATED

I'm sure help is on its way, but did you not get supplied with handbook and appliance instruction books with the caravan?

Hope caravan hasn't gone the way of computers and TV sets etc. no instructions and one is expected to go on the internet for them to read and download.

1) Space heater is for the 250v supply to the space heater elements.

 

2) Water heater is the same for the water heater 250v elements, if your ALDE is a combi system this isn't used

 

a) I haven't any experience of ALDE heating, however I think the only way switching these off would affect the heating and water heating on gas would be if either of these switches provided a 250V supply for control circuits.

 

b) Turning them off will have no effect on  on the rest of the systems.

 

c) If they are left on, the only way power will be used is if the hot water or heating system is set to rum on electricity, is switched on and the thermostats are calling for heat.

 

d) The ECO 500 is a combined 250vAC  and 12vDC  protection system, the switches and fuses on the left cover all 12vDC circuits, those on the right cover all 250vAC circuits

 

You also have, from left to right an RCD to prevent electrical shock, MCB 1 covers 250vAC sockets. MCB2 covers extra sockets and space heater, MCB 3 covers fridge, water heater, 12v charger

Many thanks silversurf, I think ! That’s what I was kind of thinking, we’re currently in Spain being charged for electricity hence the questions, we seem to be using more than I would have expected, considering we’re using gas to heat water and space as required, I’ve now shut off the water heater and space heater buttons so hopefully with just the fridge set midpoint and the television only, we should drop below 4kw

Yep, no instructions, just been on line to find them.

Apologies,I have responded, thanks for the prompt response

With the alde heating control panel there is a lightning icon that shows when using electric for heating / hot water

you can turn off the electric heating via the control panel, or set various power levels ( I think 1,2 & 3 kw). Also you can set gas or electric as priority supply. This enables you to, for example, use gas for most needs, but also use electric for peak demand.  

Its worthwhile downloading the alde manual, lots of features are built into the system, but you need the manual to understand them

I think I should be using your handle, every time I look at a manual I get lost in the wilderness, thanks for the comment and advise

Hi johhnyboy1

On our previous Clubman and our present Delta, the space heater switch doesnt work anything.

Are you now happy and understand everything you need? I'll keep an eye to see if you come back with other questions.

(I havent been on the forum for a while, very busy doing other things.)

Bubble2015, thanks for you Help, I’ve just asked another question but I’m absolutely useless at bloggs so I’ve no idea where it is, if you find it you might have an idea on how I can resolve our fridge issue.  Many thanks in advance
