I am updating a Honeywell Q674L thermostat to a Hunter 44428. The problem is the old unit had an "L" wire connection (it was a brown wire). Searching online, it seems to be the L is a systems monitoring (huh?) line, but I still don't know where to connect it. The new t-stat has R, Y1, W1, W2, G, O/B, E, A, and C terminals.
Also, the old unit had a jumper line between E and Y. Do I do that with the new one as well? And finally, the old unit had a W2 connection, but no W1 connection. Do I keep it this way on the new T-stat? Thanks!!
