The size of the duct is 8 inches or so - we have 17 heating vents and 7
air intakes - though some are joined in the system. Should I
add vents or intakes or make the plenum bigger - have people
10-15% increase in fuel consumption?!?! wow that defeats the
whole purpose. for us in Vancouver, the temp outside is 1-2 C
colder while we have inside temp 1-2 C warmer, also my wife
is on maternity leave so the heat is on all day as well....with all
this the fuel consumption is up about 70% - I think it is a relative
savings from last year.
The setting for the ramp is the slowest (takes the longest is go

2 wires and is controlled by the main board.
