The wifi connection from worcester boiler to room thermastat Honeywell Cm921 , boiler not receiving signal

Can't help you directly, but Honeywell will have user instructions on their website.
It's something like holding the 'stat within a metre of the boiler when the batteries are inserted. Best to RTFI.

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 just had a new boiler fitted and wanted to run the thermostat (honeywell cm921) on auto, the electrician set the timer to come on at 1 & off at 2 disabled at 3 & 4 and on again at 5 and off...

Complicated because I need more info....but in General a Boiler should not be on a Programmable Thermostat as it takes too long to heat you have Radiators in your house???Or ductwork for heat???It will make a difference...if you put the boiler on a program it may come on anyway as some boilers maintain there own internal temperature regardless of the thermostat.....if you want to run it on a program adjust the temperatures so there is only about a 2 degree swing....70...down to 68....back to 70.....etc...there should also be a switch in the thermostat to set for Boiler...or Electric heat...make sure that switch is on...otherwise its difficult to give you a more conclusive answer
