Installing Electric Heat problem

My basement is wired for a heating so I'm in the process of installing. I've run into some problems.

First the wire setup as it is:

Set of 2 BLACK/WHITE/GROUND one end at floor (for baseboard) other end where Thermostat would be.

1 set of BLACK/WHITE/GROUND (assuming its the power supply) one end at thermostat other end next to junction box (not connected).

Looking at the heating around the house, I purchased standard 5' and 4' baseboards (240v). And Honeywell programmable thermostat for Electric baseboard 240v (4 wires, 2 black, 2 red).

Question:
How should I connect wire for the power supply to the junction box (theres a RED/WHITE/BLACK wires coming ... I assume thats 240v)?

Do the two black wires on the thermostat marked (L1/L2) get connected to the power supply (WHITE-L1, BLACK-L2)?

And T1/T2 get connected to the wires going to the baseboard heaters? Does it matter how connect 'em?


I made a failed attempt already ... the thermostat turned 'on' and I increased the heat 80 (hold) but there was no reaction. Either I have the wiring wrong, or my 240v connection is wrong, or I should be using 120v baseboards instead (and a different thermostat) or....

Can someone help me out?

Thanks,
Sam

The tstat said 220V but what do you have on the line there

Set of 2 BLACK/WHITE/GROUND one end at floor (for baseboard) other end where Thermostat would be.
Do you have 220V here?????

That was wrong model, here's the correct manual:

To answer your question:

There no 'juice' in them. I used a voltage tester and there was nothing. One end is at the floor and other end is coming out of the wall.

I took the BLACK end and connected it to T1 and White end and connected it to T2 of the thermostat. T1 and T2 are the load terminals. The other end, I connected the baseboard (black to black and White to Red wire from heater).

The wires I connected to the junction box I connected one end to L1 and the other to L2 of the themostat.

I think the problem may lie in my wiring. Is what I described above sound right?

Thanks,
Sam

Heres the baseboard heater:

According to that, if I install a remote tstat, the wires installed on the baseboard should be hot??? I'm totally confused, now.

At the junction box:
Live wire coming in has RED WHITE BLACK -- should I connect to the RED and BLACK one, so I have TWO Hot wires?

I'll wait before I do anything with the heating system until I get response.

Thanks,
Sam

Installed a Manual tstat and it started working. So the tstat was broken.

Thanks
