i need warmth! combi working on hot water but not on C/H

[philwalker531]

Hi

im new so be gentle!

I have a fastline solaris combi boiler. It uses a towerstat wireless thermostat. I have noticed recently that the central heating has stopped working, the hot water works fine. I have tried new batteries in the wireless thermostat, different frequencies for the thermostat and still no joy.

I also tried to bypass the thermostat ( disconnected the cables from the main board) and just use the built in timer on the boiler but still no central heating. It must be something( obviously) any pointers would be greatly appreciated, thanks

There are normally alot of faults with these wireless Rf room stats... The fact you have hot water indicates the boiler is operating correctly, i would suspect the boiler has lost its signal to the stat and is not recieving demand to come on.
Is there not an override button on the reciever unit? Its normally next to the boiler.

I assume you have checked the silly things like low pressure and such

 

[philwalker531]

no it just has an on/off button on the receiver. i did initially think it was the receiver as it shows the power light but doesn't show the green 'recieveing' light when the little fan symbol displays on the transmitter. but i cant figure out why the C/H didnt work when i disconnected the wireless thermostat and just used the boilers built in timer ?

would a new wireless thermostat be a cheap place to start?

 

[philwalker531]

yes, the lcd flashes blue when that drops and shows an F$ number, got spanked £120 to figure that one out!

Did you fit a link when you removed the wireless stat connections...? Some boilers come with a link that you have to remove to fit a room stat option.

yes i read the manual and it mentioned that too - and it did have a small wire link still attached (i assumed that bit would be for a wired thermostat option) the wireless reciever was wired into a plastic connector block that plugged onto the main PCB.

I appreciate your efforts peeps.. keep em coming thanks

 

[philwalker531]

my big worry/fear is that it could be the pump or something else in the boiler that im not allowed to touch!.... is there a way of testing the pump to rule it out??

 

[gassafe]

the pump should operate on hot water... so that should be okay

 

[GasmanxxxR1]

Is the heating thermostat on the boiler turned up

 

[philwalker531]

well i think £30 on a new wireless thermostat will be a safe bet then..... i can always flog it on flea bay if it still doesn't work! thanks

 

[gassafe]

I must admit i have never heard of a Fastline Solaris combi boiler?? Is it just me?

 

[GasmanxxxR1]

I havny either

 

[philwalker531]

Is the heating thermostat on the boiler turned up

yes, i followed the starting up proceedure from the manual and everything was turned upto the max. the wireless transmitter was 'demanding' heat but the boiler werent doin wot it aughta!!

 

[GasmanxxxR1]

Why are you assuming its your room stat that is broke

 

[philwalker531]

Nope.... !!! its a Heatline!! where ddi i get fats line from??

Heatline Solaris 30PC - sorry

 

[gassafe]

Ohh a Heatline .... say no more

 

[philwalker531]

Why are you assuming its your room stat that is broke

Mainly because the hot water bit works, the transmitter seems to be doing what it should but the receiver doesn't 'flash' when it should be receiving. it very well may be that the green light only comes on when the boiler is working - i honestly don't know what to try and i cant afford another bill this month, i told the wife to put a jumper on but she aint havin it!

 

[philwalker531]

:hanged:??

Ohh a Heatline .... say no more

 

[REDSAW]

its a no heatsline.lol.

watch the language abrieviations phil!!!!

 

[philwalker531]

its a no heatsline.lol.

watch the language abrieviations phil!!!!

i guess you wont have it that i was referring to male chicken! sorry

 

[REDSAW]

no, its the bit before ddi.

 

[philwalker531]

Just to fill you in..... It was the wireless receiver that was fubard... And the chap who posted about the link wire was spot on!!! The reason it didn't work without the wireless bit on was because I didn't link the pcb bit which wasn't mentioned in the manual! Thanks for your help

 

[wazzer]

Bet its the ch thermistor

 

[gassafe]

Glad you got it sorted. Its nice to follow up the thread when you solve the problem also =]

I hope you bought a quality Rf stat this time or you will be in the same posistion next year =p
