Fw: Replacing and automating the Central Heating switch (PIC fixed)

Additionally, I dont know of any temp sensor for Comfort or CBUS (for
CBUS
it would need to pass a value to comfort)

With a standard twin zone central heating, there's no value in me
automating the temperature control bit.

Unless I add automated valves on the rads themselves, then it would be
advantageous to have temp control per room.

With my method for now, I can then call up the house and turn the CH on
remotely. But thats all I can see that will add to the experience at the
moment - apart from getting rid of the timer in the utility room

Gareth,

I agree with you regarding computer control, and prefer to keep my HA in
dedicated controllers. However I was very interested in Simon's post
recently about the heatmiser thermostats. These have 4 temperature/time
zones for mon-fri and 4 for the weekend. They can also be remotely
controlled via an rs485 link. My plan is to use the stat as a stand
alone boiler controller, then allow PC/comfort to vary the set point as
required. If the HA goes down for any reason, then the stat will simply
revert controlling the heating as per it's settings, and you loose any
additional HA features until the system is up again.

In theory it will work...

Iain
