Re: Gas boiler control

[Dave McLaughlin <dave@xxxxxxxxxxxxxxxxxxxxx>]

Hi Pete,

I have done something with an oil fired boiler in replacing the
controller for more control and functionality and I know Brian Reynolds
has done something with the timer on his gas boiler. As yet I have not
implemented the temperature bit but that is coming in the next release.
