Replacing the high voltage baseboard thermostat

Hi,

As our power bill skyrocketed this winter we purchased the new Honeywell Aube 7-Day Programmable Baseboard Thermostats (TH115-A-240D)...seven of them...
The problem is that after I shut the power off and removed the first old Honeywell manual thermostat off the wall: all 4 wires were black (not as I expected 2 red ones and 2 black ones).

Now I am not sure how to wire the replacement...any advice?

Thanks!

First question:
Are there markings for "line" and "load" on the back of the existing stat?

Second question:
Do you have any tools to test for continuity. Either a VOM or test light and a general understanding of how to use it?

Hi NEC,
Actually there are markings for Line (L1 & L2) and load (T1 & T2)...I realized it after I posted...so maybe it won't be so bad... I will mark the wires before I disconnect them.
I do not have any meters to test for continuity... I can borrow one before I turn the breakers back on. Do you think I should do it, what is the risk of not testing (blown heater/thermostat?).
Thanks!

Naw, if there is a dead short the breaker should trip. Doubt if things will be desroyed should you hook them up wrong. Just turn the power off when you hook it up. And turn your head when you fire it all back up............. If you missed?....... Post back and relax my friend........ We will figure it out together.

Thanks, NEC!
I marked the wires and connected the new thermostat. Turned the power on and voila - all works. I hear the baseboard going on and off based on the temp on the thermostat.

YEAH! - One down, six more to go...hope my electrical bill goes down.

Thanks again!
