Question about herpstat

I have proportional herpstat and they have 2 cords right? One in the main socket and the other have 3 sockets. My question, what is the function of the other one that have 3 sockets?

Thanks!

are you talking about the cord that you plug into the wall that powers the thermostat and the cord that you plug the heat sources into?

if not can you take a picture about what you are talking about?

ah ok I understand now, the other cord is for heat source like flexwatt heat tape, is it correct?

Yes, the cord with the "male" plug powers the thermostat, and the cord with the 3 "female" plugs is used to plug the Flexwatt into.

ok thanks!

There are a number of ins and outs of the herpstats you should find your model and read over the manual. You can copy the text into a translation program to perhaps make it easier or more scrambled depending...
