Yes, indeed but you have to connect right wire to the corresponding
terminal. W1 means 1 stage heat, RH means 24V AC control power lead, H
meaning for heating. If you cross this wires you may damage the 'stat.
Take a look at the furnace end to see if you can sort out this two
wires. If you measure the voltage between furnace frame and this
wire, one showing 24V AC or so is one for Rh terminal, the other one
is for W1. Some times wires are color coded.


The instructions state that RH and W1 are the terminals to use. Even
if the "contacts" are solid state, mixing the wires would not hurt
anything.


It might not recharge unless the "line" is correctly connected to RH.
Otherwise, I agree.
