RE: Re: X10 central heating control

I wouldn't consider this as a replacement for a manual system, but in addition to it. The timer works perfectly adequately, and has a manual override.  I see the X10 control as a method of supplementing the timed control based on external factors (temp. change, telephone call etc) If the PC system fails then the heating and water carries on exactly as it used to, but all the time the PC is running I would have the ability to override the timed events.

This is something I plan to do, but unless you have a dedicated controller such as Homevision, or a way ensuring 99.99% reliability for the PC controlling it, you should make sure you have a way of reverting it back to "time switch control"

 

Consider the scenario:

 

You go out to work, and the house has a power cut, the PC falls over, (or if you're lucky the UPS powers it down).

The power is restored to your house.

The central heating will now be off until you come home. and one cold house it will be in the winter!!

 

I was looking at a way of switching between the traditional time switch in the house and X10 control, using some logic, so that if the power to the house goes, then the heating will revert to using it usual timer.

 

My time switch does just act as 2 relay switches for the heating and water, so this should not be a big problem.

 

Anyhow just thought I would share my thinking.

 

Regards

 

Daniel
