Result Result Result! I managed the fool the sensor so it thinks it is 76C when it is actually 72C (i.e. I managed to add 4C offset by modifying sensor resistance). So thanks to those wwhich came back with ideas and help.

Thanks. I tought to isolate but pipe runs under floorboard and I thought it is to much to do this time of the year and yet we have babies! I will still measure temperature but I tend to manipulate the sensor via resistor to make it thit it senses warmer temperature. I will keep the list posted.

Thanks for your time. Yes you are right I have seen an installation report and it says max store temp can be achieved is 70C. And whoever installed the system did not understand much about Boilermates requirements (although it is in the installation instructions). Anyway I will measure flow temp...

Thanks. I guess this is the issue! It is reaching maybe just above 75 and with a loss on the long pipe etc from boiler to boilermate it never can make store temperature of the system above 75 which is required by sensor!

It is baxi solo (I think 30). I have temperature sensor (thermocouples with copper pads plugs into reader)

I wonder if I reduce the boiler pump speed Do I get temperature increase due to the fact that water will spend more time in the boiler while heated! Pump is at max speed currently!

On the PCB there are two push buttons and you can go through all the sensor readins as well as set points. There is a 7 segment two digit display which shows the values. Thanks

Thanks for the reply. Unfortunately, Boiler is already at max!

Here is an idea: I think midpoint sensor is NTC so I need to add a resistor in parallel to make PCB think that stored wtare temperature is more hot. I need to measure NTC resistor to gind out its spec then add a potentiometer to tweak the value then I can add fixed resistor!

Hello, I have Boilermate OV A-Class installed at home that we have recently moved in. I have realised boiler pump is allways on (i.e. boilermate's hot water function demands heat always). When I have opened up the boiler and checked the circuit board I have realised Middle sensor set to 75C...

Dear All, I am writing this to give solution to the problem described at the topic. After reading this forum and some others, I found out that issue is due to anti-flood sensor. When base of the dishwasher (I am talking about the white plastic base of the dishwasher where it has pump cables...
