I have a honeywell cm927 control unit, and the red light on the receiver keeps flashing. i can manually turn the boiler on and off at the HC6ONG receiver. i've tried the faqs in the manual but to no joy....


The red flashing light means that there is an issues with the RF comms between control unit and receiver. You can reset by switching the boiler off and back on and then re-sending the temperature signal. You need to check batteries in you thermostat and also the position as the signal could be interfered with or it may be too far away from the receiver.

I have an ideal standard he30 boiler instaledi have an ideal standard he30 boiler instaled about 6 weeks ago. the boiler keeps losing presure about half a bar every 2 days if i dont top it up it will trip...


Hi,
You have a problem that the installer does not know how to fix so they are just stringing you along hoping that you will give up and find some one else or forget about it..
You need to tell them to
1. fix the boiler correctly
2.take it back out and give you a new one at their expense
3. or tell them you will call another comapny to fix it and will give the bill to them to pay.
You did not get what you have paid for... do not pay them any money to come out and troubleshoot the boiler.
The boiler should work as the instructions say or someone did something wrong...
Sometimes it is best to call the boiler company and talk directly to their Tech. Support people.


I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Red LED on honeywell r6660d


The problem is that the 2 units are "not speaking to each other". this could be caused by low batteries or a loss in signal caused by a powercut or an objection in the way of the 2 units.

first you need to turn the power off to the r666od (or otherwise known as the HC60NG) for 10 secs, then turn back on. then hold the grey button in for 15 secs. release then hold in for a further 5 secs.

go to the honeywell cm61 press the off button. hold temp up. temp down and prog 1 in for 3 secs until the dipslay goes to INST. at this point release all 3 buttons then press the i button until a beacon starts flashing.

this is now the end to your problem.

N.B the reason the green light was on is because the man override button will have been pressed.

hope this helps
