I think this may be a slightly left-field sort of question and it relates to programmer modes or types. From what I understand, there are basically 2 types of programmers i.e. (1) basic on/off on a set temperature keeping the boiler and pump running until the set point has been reached and...

The documentation I have seen does day that if there is a 2 degree difference between the set point and temperature, either way, that it will stay on or off permanently, depending on the case.

Oh. I realize that I may have misunderstood the question. And if what you're actually asking is the temperature offset, then yes, you can take it up or down a couple of degrees. The instructions are online on the Drayton controls web site.

Drayton have told me that this is due to the design. It's called Pulse Width Modulation and triggers the boiler in 15 minute cycles. At the beginning of each 15 minute cycle it determines how long to run the boiler/ heating based on the set point and current temperature. What it does is...

All I traced the issue back to a bad solder joint on the control board (specifically on relay 2) which I assume is the one that activates the pump. I re-soldered the pin and that fixed the issue. I suspect though that the relay has a bad contacts inside causing the pins to get hot. So it...

Sorry Another update I managed to get all the water to drain by lifting the red arm which is driven by the water safety float in the base. Now to work out why it won't do that normally.

Hi All A twist to the plot. I managed to get to the pump (thanks for the info - getting in through the front is pretty easy. The pump looked surprisingly good when I removed it which made me think it may be a red herring. I refitted it and going though some test cycles and watching water...

I will check for any blockage once I get in. Will report back on progress tomorrow :D

that sounds ominous I will have a look at it in the morning. thanks

thanks for the reply I had a look through the Bosch and is helpful for parts but not with instructions about gaining access into the machine.

Hi i have bitten the bullet and ordered a replacement drain pump as I cannot hear the pump at all and the system stays full of water. Problem is that i cannot work out how to get access to the pump. I've had the left side panel off but that doesn't work and I looked at the bottom but that...

yes, in that vicinity 45-46mm. It's a single panel.

thanks for the prompt reply. I assume tail centers means wall to center of the fittings. In that case mine are 45mm.

Hi I am trying to locate new radiators to replace existing but have realized that newer radiators have different sizes and installation dimensions. Besides the fact that the lengths have changed, the distance out from the wall has changed making it necessary to modify the piping, but with...
