Central Heating

[Countrygirl]

Hello

I am looking for some help with my central heating system.

I have a Switchmaster 900. I've got the whole green/yellow red/blue for the on and off timer parts. My problem is that the timer is not on the right time, so when I've set it to come on a 6am, the timer thinks 6am is more like 2am.

How do I set the timer to the right time?

Thanks in advance for any help offered.

Liz

It sounds like a standard dial timer. There should be an indicator around the edge somewhere that denoted the current time. Rotate the dial until it shows the right time.

Hi

Thanks, unfortunately it doesn't appear to have an indicator. It has an advancement dial to the left of the main dial at about 5 O'clock. On the indicator it has a little triangle.

Does this triangle correspond to the time on the main dial?

Kind regards
Liz

Do you have a photo of it that you can upload for us to see?

It appears to be an aged controller and no longer produced.

Hi Steve

Now your going to realise how rubbish I am....I haven't been able to find an image online, and I can't work out how to attach a pic.

So I've emailed an image to the forum admin, hopefully it will make it!

Kind regards

The little triangle should point at the current time. The big dial should be shaded, black and white to indicate night and day. You only need to rotate the dial (it will rotate in one direction only; normally clockwise) to place the triangle on the current time of day. eg, if its 3pm turn the dial until the 3 in the white sector is at the triangle. Check that your on/off tikes are in the night and day sectors as you require, and thats it.

The advance function simply fools the timer into thinking that it has reached the next event (ie its time to come on or its time to go off). The system will remain in the new mode until the real next event.

Hope this helps.
