TH132 is a thermostat for under-floor heating
Go to the website above and download on-line copy of your manual
On-line manual let you read bigger print & lets you break down the steps easier

I am sure by the time this answer reaches you, the problem will be solved
This is true because manuals are frustrating, until you tell somebody it can't be figured out >> which gives you time to rest >> after which the manual makes sense.

BUT I am frequently wrong, and you may be at a standstill
A quick look at the manual.
You can also select which part of the manual is giving you a problem and then I will help you through that specific difficulty

Wiring: I guess the instructions at bottom of manual apply to your model
Your 240Volt hot wires from breaker box connect to terminals 1 & 5
Your two wires supplying power to heat connect to 2 & 4
Pilot wire to terminal 3
Floor sensor to 6 or 7 >> wire from sensor can connect to either pole
The TH132 has two sensors, 1 located inside the TH132, the other sensor located in floor

Set up:
The first part describes 10 buttons (right away you know this is complicated)
There is a brief description of both sensors
Step 1 shows how to configure the start and temp-display switches

Step 2 covers installation of module on base
I guess you hook up power at this point because the display is supposed to light up
This implies that the bottom part of manual should be located more towards the top, and the power-up directive seems to be missing. Bad manual.
Step 2 shows what the display looks like with first power-up

Step 3 tells how to set current time and day.

Step 4 adjust temp setpoints >> floor temp is pre-programmed to 82 degrees

Step 4 shows that you press-and-hold the sunshine or moon button to have it display
The sunshine button is the upper temp setting, the moon is the lower temp setting

Step 5 is operating mode > choose automatic for programming to operate

Step 6 is programming, which carries on with about 24 steps
If this is your problem area, let me know
Now the manual suggests you make a chart of your programs
Other programmable devices don't work when there is a conflict in programming

Wow I see the TH132 is 'equipped with a proportional adaptive controller..' that carries a two year warranty. I'm sure you'll rest easy knowing that.
