Thermostat Reset

Hi All,

Apologies if this is a daft question but I've recently taken ownership of a property that has a Pusacoil III hot water system ... naturally the previous owners didn't leave any instructions behind!

Since moving in I've worked through a number of basic issues:

• I now know the off-peak and pump switches should be on, with peak turned off in normal configuration.
  
• I've topped-up the water resevoir
  

To cut a long story short unless I turn on the peak switch (and of course pump) I have no hot water. The 2 green lights on the front of the appliance currently both flash green.

Clearly there's an issue with the main off-peak heater does anyone have any advice on what I can check do?

I've seen talk of a need to reset the thermostat manually ... any pointers on where/how to do this?

Many thanks for any hints and tips,
Andy

Hi Andy,

Please find a link to the instruction manual.

The original overheat reset button is the little brown button next to the two green lights on the front panel, but if it was tripped it would stop both heaters from working. You have a problem with only the lower heater so we know it is not the brown button popped out.

Either the lower heater element or it's thermostat has failed. Some element thermostats also have their own internal overheat trip. These are the turquoise coloured thermostats. Take the black plastic cover off the lower heater head and if you have the turquoise coloured thermostat, the reset button is a tiny (microscopic!) black button between the two terminals on it. Press it in with the point of a Biro. If it clicks down, it was tripped, if not, you probably need a new heater element.

There is a browny/red reset button near the neons, just push that in.
