Ohms value
Anyone know the resistance I should expect the tank sensors @ 30C

No, according to Gledhill you can not test them.
Does the ACB not tell you if they are faulty?

Re: Ohms value
Odd as all thermistors have a variable resistance, I have no fault code, however as I have not fully read all the manual I may well have, I intend powering the OP element remote from the OP meter to see if it actually works as I have a sneaking suspicion that all is not well with the supply from the meter

Re: Ohms value
You have 5 sensors on the PC A class.
What is your problem?
Is the unit hot?
DHW?
Over heat sensor?
Keep an eye on the relays!

Re: Ohms value
Well test the bottom heater. Around 19 ohms.
And;
Remove the off peak supply / connection flex.
Make safe Be safe.
Connect a short piece of 1.5mm 3 core flex to the unit off peak.
Plug top on the other end and test that way.
You have 5 relays on the PC A class.
Off peak and on.
Interface relay
And 2 on the main board.
If using boost as soon as a supply is put on the off peak then the boost should stop. (interface) Can not use both supplies at once.
If by using the temporary supply to the off peak all works ok.
Then you have external off peak supply problem.
