Air handler wiring

[HAB]

I have a 4 wire cable running from thermostat to air handler. I am running electric heat and ac. The board in the air handler is #HQ1085914TX. Connectrios -,W2,G,Y,H,O,C,R. The thermostat is a honeywell T8112D1005 with connections R+R,Y,W,G. Can this be hooked up with 4 wires and which connections would I *
Thanks,
HAB

Follow the wiring diagram on page 3, Fig. 4. Please note the thermostat is set for gas heat from the factory so refer to Table 1, page 2 to change the dip switches for your electric heat. Turn off all power before doing the wiring. And check the wire colors at the thermostat and air handler to be sure there has not been any wire splices (change of wire color).

from what i see with the tstat u have dont connect h,o,c, to anything and as far as w1 and w2 assuming u have 10 kw heat make sure ur high voltage wire feeding the a/h is properly sized if so tie w1 and w2 together if not just connect w1 to ur w wire coming from tstat.
