    If you are wiring this for heating-only, and you only have 2 wires to the thermostat, connect one to "R" and the other to "W1" and "W2". Insulate or cap the remaining 2 wires, then test the operation. If the electric heaters turn on but the blower does not, add the "G" wire to the "W1/W2" junction.
