How Do I Install 7 Day Programmable Thermostat With Four Wire System?

I have red green blue and white wires. I followed instructions in manual and heat works but a/c doesn’t. I used programmable during the winter but had to reinstall my old thermostat for summer. Connections on new thermostat are G, Rc, Rh, Y/O, W/B, Y1. There is a jumper preinstalled from Rc to Rh. Thanks.
