Hi all. I recently purchased a house and yesterday tried to figure out the heating system. I thought I had but now it doesn't seem to work.
The system is as follows:
- Vokera Compact HE25
- Thermostat - Salus RT500RF (also badged as an Altech014)
Despite the somewhat confusing salus instructions a combination of common sense and more so the threads on this forum I programmed it as follows:
1. 6:00 at 21 (so at 6am it heats the room to 21 degrees)
2. 8:00 at 10 (so at 8am it effectively turns off/comes back on after 8am if room temp. falls below 10 degrees)
3. 18:00 at 21 (as above)
4. 22:30 at 10 (as above)
5. 22:30 at 10 (so it remains effectively off until 6am the next morning).
The good news is that it worked this morning and the radiators heated up nicely. The bad news is that it isn't working now. The thermostat is telling me the room temperature is 17 degrees and there is a flashing symbol (a flame?) so I assume it is calling for heat. A quick trip up to the loft and what appears to be the receiver attached to the boiler I have a green solid LED and a red solid LED. I assume one is power and one is calling for heat.
I have checked the boiler and the water pressure is just above 1 bar. I have a green flashing LED on the boiler at approximately 5 second intervals - looking at the Vokera manual online seems to suggest this is in standby with no faults. Note that I can't hear a noise from the boiler which I may have expected if it was firing and heating the radiators.
So - the thermostat seems to be fine, the boiler seems to be fine, and the system and radiators all worked on this mornings program.
Any ideas?!
