Sleep walking could be dangerous or it could be the home of a very tall person.

As JohnD is possibly inferring, a long run of flexible duct will seriously hamper the flowrate through the fan. Flexible ducts whilst handy to install should be used to as minimum as it causes quite a lot of resistance to airflow.

A few months ago I had what started out as an intermittent fan noise on an AEG built in oven which developed into a permanent noise. Fearing the worst I removed the fan and all seemed okay; a bit of longitudinal movement along the axis of the motor spindle but nothing too serious. I refitted it...

Sometimes the air temperature can read okay but the feel of the room tells you different. This used to be known as the resultant temperature. A simple way to describe it is when you step into a hotel/motel room that feels cold after you have activated the heating with your room card. Although...

Speaking from personal experience of outside weather compensated systems in a commercial environment. I always found that Autumnal weather often presented the most challenging in achieving a satisfactory internal temperature in relation to outside temperature. A sunny spring day but cold day...

Hi Eric, I'm not sure about IFTTT but the fan on the SpeedComfort switches on when the radiator gets warm it isn't thermostatically controlled. You will find if you use a SpeedComfort that the room will heat up faster and you will not need a high setpoint if you have a room stat. You will save...

I suppose it depends upon each individual house. In my limited experience I have found that I now do not need to switch on the electric fan convector in order to bring the room up to a comfortable temperature. The boiler is running at a lower flow temperature and the room is comfortable at a...

I have been using one of these [Twin unit] since May this year. I only tried it as fitting a larger or extra radiator would look very odd in my living room and the pipework would be unsightly. The links don't seem to work so just type in SpeedComfort radiator fan. SpeedComfort | Smart Radiator...

Funnily enough I've just been trying to fathom how the heating curve works. With the commercial systems that I have previously had experience of, the heating curve worked as follows. Outside temp 0C flow temp 80C. Outside temp of 20C flow temp 20C [Off]. A heating curve of 3 will give a 3C rise...

Many thanks for the info on here Ladies and Gents and I have taken it on board. Wayne of Secure I AM has been a great help in selecting and getting the equipment for me at a decent price. What has been more important has been the technical help in setting it up. I don't think I could have done...

Most of the sites I come across are set up for Trade only by the look of them. When I was working a couple of lads who worked for our security contractor offered to do the job and it now sounds as if it was a cheaper option than buying and installing the kit myself. However I am looking forward...

Interesting info thanks folks. I think it may be spiders that have given me a problem with an outside security light with a PIR. With regards to light reflection off existing lighting and IR reflection off a nearby pillar I will first see if one of the cameras positioned over the garage can...

That's handy to know as I have an Amazon Fire box which is basically an Android box which I have loaded additional apps to. Much cheaper than a long HDMI cable and much better to hide the NVR away as you said.

Cheers for that info as I was wary of opting for the 8mp cameras.

Before you jump down my throat, I've had a good look for my specific questions on this forum and other places and have found many useful answers. However there are a few more questions which I could do with resolving before I drop a clanger on purchase and installation. The system will be a 4 -...

Cheers Gents.

Cheers Jo, job sorted. I tried this for users X003, X004 with no luck as I didn't know the existing codes. However this has enabled me to add two new user codes. I will leave the mystery codes. I did try the soft reset as previously stated but it didn't blank out all the existing codes. I didn't...

Problem solved but I don't know how as it just started working correctly after a day or so.

Hi, I have the above 16 zone panel with two 9930 keypads attached to an SD1 Menvier dialler. I would like to add another user to the system as per the user manual and find I cannot amend the existing codes apart from the two that I know are in the system. I believe a total of 8 different user...
