NOBO system 500 - some thoughts

Hi,

I have been following some posts here. I have a Nobo system 500 as well, and it looks like the controller unit - the Orion 512 - is not working. Some zones come on and off when they shouldn't be, the bathroom radiators are constantly on, and the immersion heater is erratic.

I have tried to locate a replacement Orion 512, but am out of luck - it is discontinued.

I rang Creda (NOBO UK) - and they say I probably have to upgrade to a system 700.

I can order the parts from a wholesaler, but have no idea how to fit them - and replace the RSX recievers, etc...

Can anyone help here? I live in Croydon, London.

Thanks!
Alex

Thanks Mike. I'll ring Gledhill tomorrow.

Google didn't come up with much for me.

Which homepage do you mean?

Hi unfortunateley the nobo controllers have been discontinued, gledhill dont supply an aftermarket timer, i replace the nobo ones for hard wired immersion timers (do not use plug in ones). i charge £60 supply and fit for this service but only cover the southampton / portsmouth areas. hope this helps.

Alex, this is a Gledhill repair forum.Your issue is with the NOBO programmer. Although £60 is a good price for the immersion timer replacement, please note that the repair been offered is ONLY for the RSX512 replacement. Judging from your post the programmer signal is the fault not the RSX.

The Orion 500 system is not been manufactured any longer ( replace by the EC700 ) but I am aware of engineers in the London area that can repair that system. It will not cost £60 but will allow controllability of the heaters / towel rails / immersion heater through a single programming unit.

Obviously the cheapest option is to fit stand alone timers on the immersion heater and if required the towel rails but the heaters will then become stand alone heaters with no facility to time control the setback / comfort feature. Many people only ever turn the heaters / towel rails on then off anyway and do not use the programmer !!!

If this is how you use the system then stand alone timers will be the best option.

the timer only replaces the nobo receiver which are crap and become stuck off, the orion still controls the towel rads / heaters etc. just seems to the the receivers on the gledhills which you cant fix by the way.
