I am wiring up a itc-106rh. It is wired the following way with input voltage of 120v:

3- thermocouple neg  
4- thermocouple pos  
7- line out  
8- line out  
9- line in(hot)  
10- line in(neutral)

It’s my understanding that when the light below the “OUT” label is illuminated that I should be reading 120v between pins 7 and 8? Is that correct?
