Question about Honeywell Programmable Thermostat Heater
On paul 306, I don't have any info on you're system, but the old thermostat that has the smaller wires with the colors you described is a low voltage (24volt) controls. The new one you purchased sounds like it is for a system that is made for line voltage (120 volts or more) connecting this to the unit may have bad results. This also may apply to GUEST.
COACOOCHEE, the white and black coming into the box is the line, even though white should not be used for line, the connections for the other side of the thermostat is the load. The new thermostat you have be a single pole break as opposed to the old one may be a double pole. You should have a meter to check the voltage coming into the box, it may be 120 or 220 depending on what you have. Without any more info I cant be sure, but you may be able to connect the black wires to the switch and the white together. But it would be wise to test with a meter to be sure before doing this.

How do I install a basic digital thermostat?

Any thermostat for elecric heat breaks the line/load connection as you said. Your old thermostat broke both the hot and the neutral. I would recommend first that you consult the instructions with the new thermostat or go to their website at http://yourhome.honeywell.com/home/Products/Thermostats/SummaryList.htm
to use their online help. Without seeing the instructions or the thermostat I think you are probably right. I would hook one black to one, the other black to the other, and the whites (which are neutral) together. Let me know if you need more help but check the website.
Thanks for using FixYa

Testimonial: "It is a touchscreen. I have seen references to the battery being round and lithium CR2450; however, not sure if this is accurate. Does anyone know?"
