Thermostat Help

[Jafo]

I am installing a Honeywell RLV430 thermostats for my electric baseboard heat in the basement and in the living room. The old thermostat in the basement had two wires and the bare ground wire. I hooked the two wires up and the heat works fine, though there was no place to connect the bare ground wire? Is that ok?

My BIG problem is with the one in the living room. This connects to two baseboard heaters so the old thermostat has 4 wires and I am unsure how to make that work when there are only two wires from the thermostat. The diagram I linked to shows how your supposed to do it, but that is a bit confusing. I have attached a couple pictures here of what I see, can anyone help?
