Thermostat wiring
I am new so pls understand. I am replacing an old Arcoaire thermostat for a heating and cooling heat pump. The existing wire reads like this:
W1 jumpered to E
The new digital thermostat has all the wiring letters (colors) but W1
I call the trouble desk for the company and they suggested to contact an electrical contractor. I am on a budget, where does W1 go? and is it stll jumpered to E.

Tks Sherio

But the white wire on the W1 terminal.

Need make & model of the thermostat, heat pump, air handler. Also, if you can post a pic of the circuit board were the wiring connects (please no super close up), that helps, if you cannot figure out the directions of the thermostat & air handler.
