Hi
I've just read a few posts on HVAC so thought
I
would chip in a little. I run Misterhouse SW for HA and have some weeder
digital
and analogue boards attached on a serial port. I use some LM35 (temp to
voltage
& cheap) attached to the analogue i/p's for temperature monitoring. I
believe they change 10mV per degree centigrade. I have two relays
controlled
>from
Misterhouse works out what shift SWMBO is on
that
day checks the temperatures and switches the heating on accordingly so that
the
house is warm either for her getting up in the morning or getting home from
work
later.
After the initial fine tuning of software it
as
worked fine for the past year. When I move I may change the temperature
sensing
to the dallas stuff but not quite decided yet.
Still on topic quick update - Builders have
said
the quote was for three sparkies for a full week plus some extra twin &
earth to route via Node 0. They have reduced the cost to £3100. Still not
happy
and have requested a meeting with the electrician ! I will keep you
posted.
STOP READING NOW short OT sentence
follows
.... Yes Phil the "Hooters" mentioned is the same "Hooters" as in the
US,
same everything but minus the US accent. (but plus the cheesy
sauce).
