Thermostat + Dimmer = WWB prototype

DISCLAIMER: Copy and Build at your own risk!!!

Made a prototype for a wax warm box. This one have a thermostat which i can set the temperature and it will cut of the heat once the warm box reach the desire temperature. I also add a dimmer, incase, the box get too hot a dimmer would be able to dim the light.

Installatiion of these parts are fairly easy. The thermostat is Jaeger FST ZA110C, temperature range 30°C to 11°C. This termostat have a temperature sensing of +-5°C. I searched on internet about how to wire the thermostat but there isn't any. And the shopkeeper claimed that they don't know how to wire it, so a trial and error is all i have. The thermostat have 4 metal contact: "1","2","C", and Earth.
"1" is for 400V AC 15A and "2" is for 2.5A. "C" is the output and Earth is... well the name explain it all :-)

The wires were connected to the metal contact using the "female disconnect". From the 3 corded wire, connect the Earth to the Earth Contact, Live to "1", another Live from "C" to the Dimmer "in". The Nuetral wire shall not connect to the thermostat nor Dimmer, it should go direct to the bulbs. Another Live wire is connected from Dimmer Out to the bulbs.

After all wiring is done, the bulb were hanged insde the warm box, and the probe were insert in into the warm box.
I twisted the Thermostat to 50°C, and it cut off the light at 55°C, not bad at all, for a RM38 Thermostat...

  2. i made this so long ago, please allow me to go back and open up the casing to show you how i do the wiring.
    I assume the heating element is the coil that generate heat like the water boiler?
    I am not quite sure how the wiring workd on the water boiler.
