Honeywelly9420 sundial rf pack 2

[Keith whiddett]

I have just installed the above heating system controller on a Y plan all seems to work ok but the programmer is saying no signal and rf icon is flashing. The thermostat is coming in and out on tempeture, programmes are ok but this “no signal” is bothering me any ideas please
Thermostat is a DT92e

Yea as Lee says. Unbind and rebind and do a signal check first thing to do.

There pretty good but there’s a few things that might upset it like large metal objects(boiler) too close to prog or stat, foil backed plasterboard celotex etc. blocking signal

Had absolute murder with a Honeywell Evohome once and turned out to be interference from a Sonus speaker syestem.

No I am not a pro, but have but the thermostat next to the programmer making no difference.

I would start room scratch.

I have disconnected batterys in stat which seems to reboot it. And turned power off of programmer to reboot that. It runs fine for a while but reverts back to no signal.i am using a wired cylinder stat which is not honey well would that make a difference?

 

[sam400]

No tank stat make won't matter.
What signal strength did you get?

 

[buzzlightyear]

considering that you can not get the system to work properly .
may be you should start looking to get a spark in to sort it out
for you.

Hi buzz the better version diagram you sent is not that clear like the other one. Any chance u could send it again please.

 

[Keith whiddett]

Stength of r f was 5 !!!

 

[Keith whiddett]

A friend of mine who is ex BT and has the same system in his house did the wiring and we are convinced it is as per the wiring diagram the same as the first version you sent

I have noticed that if I go from constant hot water to constant heating switching the hot water off the 3 port valve is not moving!

Just moved temp on thermostat to below the room temp and boiler cut out. Put it up again and boiler comes on so rf is working. Yet programmer says it is not! Begging to think there is a fault in programmer

With all due respect BT and electrics are different.

When I wire a heating system I run through a series functional checks when ive finished, which involves turning stats up and down and watching values switch over.
If I suspect there is a problem with the room stat is prob link it out.

Have you connected the programmer up right ? Have you got call and satisfied (also refered to as "make" and "break") right way round on the Cylinder stat ?
Is the polarity right on your receiver ?

Out of interest have you wired the complete heating sytem in flexible cable ?

 

[Keith whiddett]

Am sure wiring is correct. And cylinder stat is right way round. Except for supply to programmer and boiler it is all flexible flex

I give up....you come on here asking advice. You get advice and choose to ignore it. Unbind and rebind the thermostats.

Really very sorry but do not know what I have ignored except getting a spark in but all are to busy or don’t want to know!!

 

[Keith whiddett]

My thanks to all for any help or advise. Seems I am not welcome here, sorry to have bothered you

 

[Leesparkykent]

you say you've turned it on and off a few times but have you actually unbind and rebind the thermostat?
