help

I have recently moved into a new property & have some central heating issues.
I have a Potterton Suprimer 60 boiler & a Danfuss TP5 wall timer.
Ive programmed the timer & this works as normal.
But why does the heating come on outside the times ive programmed ?
This happens throughout the day/night.
Also some radiators are very slightly warm, where others are so hot you can hardly touch them ?
Ive bled the radiators more than once & ive only been here a week.
Any advice would be appreciated.

look for a frost stat
try to balance the rads

do searches if this means nothing to you!

timer selector should be on 'once' or 'twice'
