Im not running a relay or a fanQuote:

I sent this to TD but figured it might help someone else if needed......
Going off TD's link and my posted settings parameters above, my guess is that L5 is the same as my LA and H5 is HA. They are simply upper and lower limits that you can set the temp at. Eg if LA is -50 you can set the desired temp down to -50. Basically what you put L5 and H5 at determine the range of user temp selection once settings are finalised. I have mine at 10 (HA/H5) to -10 (LA/L5) as I can't see any reason to go higher or lower with the fridge.
The P7 value will most likely be the delay start option or PU on my controller. This means the internal relay won't close again within the set time even if the set temp parameters are breached until the allocated time has passed. I have mine set to 0. So as soon as the fridge gets 1* above my set temp the relay kicks in and activates the fridge (I have my CP value or temp difference D set to 1).
To get to the settings simply hold the 'set' button for 3 seconds....
So to summarise going off the link TD put up my settings would be:
(HC) HC = C (cooling, means relay will activate once temp is exceeded. On H relay will activate when temp drops below set temp)
(CP) D = 1 (temp variation difference, so if temp is set at -2* relay won't engage until -1* and will switch off at -3*)
(LA) L5 = -10 (lowest user selectable temp, can be what ever range you need)
(HA) H5 = 10 (highest user selectable temp, can be what ever range you need)
(CA) CA = 0 (if you have a more accurate temp probe you can change this value to calibrate the meter to read the same by adding or subtraction 1 degree at a time etc)
(PU) P7 = 0 (delay start, stops your device cycling on and off rapidly if required)
And further to that once those settings are in place all I do is tap the 'set' button and select the temp I want (ranging from -10 to 10 as per the L5 and H5 values I have set)
Hope that helps mate...
Yeah that’s what I figured, the fan is representative of the load, ie fridge.Quote:

Not that I've watched the actual fridge display but I would imagine that mine switches the fridge on and off completely, as it simply controls power going to the fridge via the standard cable. It doesn't just control the compressor......Quote:

Mine looks like its wired as per that first drawing , and in my defence I was on heavy meds at the time lol.
Mine works fine now Sooty has sorted me out, will give it a test tomorrow
Not 100% what you mean here, but mine is wired as per the wiring diagram I posted, which uses the temp controllers built in relay switch at terminals 1 & 2. I have no other relay between the controller and fridge. I do have a fridge switch up front which controls a relay activating and powering the temp controller though.Quote:

Further to that the internal relay is rated at 10A so is more than adequate to run an Engel without an external relay. The second pic that Beni C put up with the relay and fan example are really only if your using the temp controller to run something that draws more than the 10A.
Cool cool, thanks gents, will get one on order.
Thanks sooty it really is easy once you know what the values mean, now to change the plug ends and fit it,
I will be putting my thermo probe in a small plastic super glue bottle[empty]
Changed all the plug ends to 50amp Anderson and plugged it in.
I will also run a Waeco digital thermometer as well to monitor temps, when I find it lol
I turned the Engel on full and set the temp to 4 degrees there are some
cans in there left over from the weekend so we'll see
Just checked the temp and its showing 5 degrees so I put it down to 3 from 4
will sort it out properly tomorrow
@ Sooty I put an extra external temperature probe to check against the controller.
Spot on with the temps holds 3 degrees easy.
Have made 3 of these lil rippers also and they work a treat. 2 years and still working great. 1 for myself and a few mates and they couldn't be happier.
No more constantly checking the temp 2degrees.
Just got back from a camping trip to Lake Eildon, controller set on 1 degree, beer was perfectly cold and lettuce did freeze. Very happy camper.
Arrived in the mail yesterday so hooked him up to my battery box last night and have it running the Engel behind the bar atm. Works a treat! Will change the cycle on to 4 deg instead of 5 deg I think.

one of the better mods going around and not too pricey either
Must give this a bump and two thumbs up, last fishing trip my drinks were icey cold. and kept everything cold all weekend.
The lowest my battery went was 12.5 volts in hot humid conditions over 2.5 days, well worth it once you know whats what
Highly recommend
FYI I had it set on 5 and it did not vary one bit
