Another boiler or programmer problem

[kgreen84]

My ideal he24 will not fire up. 0 is displayed on the boiler and the manual says that if any problems its not the boilet. I've tried to put the heating on to take the chill off, it worked yesterday but nothing today.

Have turned boiler on and off, turned off and reset honeywell control panel but nothing. Normally when I have heating on continous and say 23deg it fires up within a few seconds?

put a link over L1 & L2 boiler should then display c

I know that c should be displayed when firing up but have no idea what you mean by L1 and L2?

maybe you need a heating engineer in i take it your hot water is ok by the way!

 

[kgreen84]

i have hot water but normally when somebody has had a bath (like I just have) the boiler fires up but nothing. Could it be the programmer rather then the boiler? That is what the manual is suggesting - there is no error code showing.

check the programmer is it on correctly

i have the heating on continuous with the stat on 30deg

posibly room stat gone
does programmer turn the boiler off when u tell it too

Do you have an Icos or Isar HE24?

 

[kgreen84]

its an icos. Think I may have found the problem (hopefully!!) the programmer now has no life in it at all, although no warning that the battery was dying before hand.

In my mind it explains things! Its a Honeywell ST6400C around 5 years old. Can I just replace the battery or have I got to buy a new one costing about £75? Would the new honeywell one just sit on the backplate?

 

[gas4you]

Don't know about the battery point, but if you can't replace it, the new programmer will fit your backplate

 

[compheat]

The battery is only for back up for the memory and display.

hot water ok? no heating? system boiler?? Motorised valve surely first thing to check??

 

[kgreen84]

hot water was only ok for a while until it was all used from the cylinder. Replaced programmer with a nice new 9400C. Dead easy fit and everything working lovely.

Saved myself a few quid on diagnostics I can't afford at the moment!

Yes but what if it wasnt the programmer?! 99.9% of times when a customer has a go them selfs first they end up spending more then it would cost to get it done by a pro
