Water not heating

[Travis]

I got a new Primaflow circulation pump installed in my home today. The heating is working fine but for some reason the water is not heating.
Can anyone help me out with an explanation please?

first thing id check is have anyother wires got dislodged when doing the pump

Have you a Y plan or S plan? are your syncron motors energising (does your moterised valve open?

This could be stuck. Not sure why you would be toutching the wiring in the control centre when replacing the pump to I wouldnt put it down to electrics myself (but no harm in testiing it)

Do you have a AAV on the indirect side?

Thanks for your help guys. Alas I can't answer the questions as I am not in the trade.
