timer settings

[mad16]

why does my potterton pro max come on between timer settings

 

[fuzzy]

is it a timer or programmeable room stat?

do you have a frost stat?

 

[MattWeth]

Do they have a 'pump saver' feature like Glow Worms?

 

[diamondgas]

As above ... The promax will run for a minute every 24hrs to protect the pump. I had a duotec do exactly the same, same time every day it would fire up! I thought it was supose to just run the pump but this one didn't

 

[mad16]

it has a programmeable room stat and it does have a frost stat but it has been 6 degrees today.

These boilers have an integral frost protection mad 16 ... is that what you mean or has there been an external stat fitted?

 

[mad16]

we have a portable room stat we can move around and the boiler is in the garage

 

[diamondgas]

The boilers integral frost protection I believe works on water temp but I'm not 100% positive and is looking for 5DegC Mad 16 ... Do you have an external frost thermostat also fitted though?

 

[mad16]

no external frost stat fitted

 

[MattWeth]

Do these extra activations happen at the same time each day? And how long do they last?

then there is no off time, only a range of temps, what is the required temp between 'settings'?

 

[MattWeth]

So we've all decided that it can't be a pump saver feature waking the boiler / pump up at regular intervals?

 

[fuzzy]

but if a prog room stat it never goes off? just different temps at different times
