So will having taken off Summer Mode sort the issue?

I can't get to the hot water setting. There is no hot water icon on the screen... I only got the heating icon on right hand side. The shows me pressure and allows me to change heat level. I have taken off summer mode.

Yes hot water on by programmer. I have noticed that there is no hot water icon (tap icon) only the heating icon on right side. Is this normal?

Yes. Pressure is fine.

Thanks. I will deactivate it and see if it helps. What should I set the heating flow temperature at?

Also what is the function of Summer Mode if we have a thermostat?

Buttons. Valliant ecotec II Plus 637

Sorry if this is laughable question. Is it in any way possible that installer connected hot water to CH outlet so hot water effected summer mode?

We have a shower in alcove. The wheels and mechanism on our 2 year old unbranded bifold shower door installed by builder has completely disintegrated. cant find any replacement parts and we weren't happy with it all the same. It never was 100% water tight with puddles outside the door and...

What type of filler is recommended?

Hope in correct section. Had new gaspipe run quite some time ago down side of house. I never noticed but they just smashed the sill and render to accommodate the pipe - only noticed lately when we moved a bed at the inside of that wall and I see that the paint is bubbling... Is there any...

I agree, credit would be really helpful.

It was just a message HELLO to show up on the panel, sent with user code. What extra commands are possible with engineer code?

I recall someone else posted a similar issue with -113db showing when though he was in good signal area. The definitive indicator on reception is the LED 3. If it is flashing then you have marginal signal which is way above -113db. It seems certain errors will just show up as-113db.

Thanks a lot for your reply and kind offer. In the interim I decided to switch the com ports and presto all sorted! (Didn't lose any settings, just set both com ports to nothing fitted and then changed the cables around and set com ports and wintex just reconnected no problem). This is after...

I had a GSM module installed and all was working my fine. I then tried to show off by sending a SMS message to panel and from then it stopped working. I get permanent -113db under status (though I know that isn't correct because the LED on the module is flashing). It keeps throwing up com 1...

YES! Is this an easy fix for a pro installer? Any of you guys work in London?

This looks like the part. http://www.hunters-wholesalers.co.uk/fc503whg2b-grade-white-flush-door-contact-type-resistor-scantronic-cooper-pyronix-texecom-castle-care-p-59347.html The part the installer left behind is the part without the wires so not much help!

As far as I know out of business and ignoring my calls! Is it skilled job to replace the contact? Does the log show anything?
