I have an old thermostat which i want to replace, but i don't understand exactly how it's supposed to be done.
It's a simple baseboard heater with no fan, air conditioning or anything fancy

It only has 2 wires, and the instructions are no good
it was supposed to be simple but turned difficult in minutes

Where exactly are these wires supposed to go

The original thermostat is meant to interrupt maaany Amperes at the current the baseboard heater element consumes in series to it. Works/rated usually on 230VAC

The replacement thermostats shown are wimpy ones meant to signal 24V relays inside an airconditioner/furnace/fan unit to turn on/off.

Wrong device for your needs. If you hook it up, will leak its smoke. For sure.

Check the plastic nut connectors have healthy, clean, tight splices inside, at both ends of the heater assembly before replacing thermostat. Diagnose, probe for continuity at the existing thermostat and voltage supply presence. It usually is :

ACphase1circuit breaker-----x----thermostat-----x------heater element-----x-----circuitbreaker2ACphase2

x= splice/joint/connector

Listen for a 'click' when turning knob.

Be careful touching live wires, will give you the giggles. Work safely.
