Hi guys!
Firstly let me introduce myself! I'm Kevin, a first year (soon to be second as of next week) adult trainee.
I've been with my company now about 5years full time as well as working summers while at uni.
Mainly working in the renewable game from small wind turbines for houses to large scale wind farms as well as marine renewables.
Generally a happy chappy although I hate mornings with a passion! There just too darn early! Haha.
So I've got a slight problem going on at home with the megaflow.....
it's mainly heated by the oil heating with the immersion as back up the immersion has its own thermostat build into it, the oil heats the water and does the heating as well so there's a 3 port valve in the system. But the oil burner doesn't seem to heat the water, meaning we have had to have the immersion on to heat the water (250l tank which is bloody expensive to heat electrically! Lol) and the immersion has tripped on the overload just once a few weeks ago, but I want to get this sorted in case the back up immersion also fails! Lol. So my question is......
how can you test the thermostat for the oil heating? I asked a guy at work and all he said was to make it call for hot water and see if the water gets hot, if it doesn't the thermostat is knackered, hardly sound advice I thought. And the fact the controller doesn't have a button to just 'call for hot water' which I thought odd...
The basics of the wiring to the mega flow for the oil burner are there is a 3core cable going into a terminal strip in the megaflow enclosure which then has factory wiring to the (I assume) thermal cut out on the left, and the thermostat on the right, the cable then goes back to a small blanked enclosure where it is wired with the cable that operates the valve and I guess then down to the main junction box for all the heating/controller.
the valve isn't sticking or anything, I've had the actuator off, and buzzed the connections on the actuator with the meter to check the micro switches are working, so happy that's ok.
which leads me to believe the thermostat it's not working right! So how do I check it with a meter...?
The really annoying thing is that after working about with it all it now seems to work. There was no loose connections or anything looking suspect to a fault all I did was play about with the connections and turned up and down the dial on the thermostat a few times to see if I could hear it click like the immersion dial did...??
But since I was stumped on how to test a thermostat on a hot water cylinder I though I'd ask you fine people!
I can take a picture if you guys think it'll help...?
