I need some electrical assistance. Ihave replaced the expansion tank with an oem tank with float switch.
Due to a fracture of the lower hose joint on the tank caused by the metal insert having slipped down into the hose, meaning when I tightened the hose clamp, the plastic broke.
Now because the switch operates in the opposite way to the maplins float switch, ie normally open i moved the connection on the timer unit from the NC to the NO terminal. All good in that the alarm sounds when the float drops,
BUT the alarm sounds immediately and stays on for the delay time.
Obviously I need to change something but I'm unsure what.
I suspect that I may need to connect the float to a live feed rather than to earth,and perhaps move the trigger to the other trigger terminal.
However I dont want to fry the timer module by guessing wrong.
Could someone with the requisite knowledge steer me right please?
