[NJARC] Need connection diagram for a Love Temperature Controller

[Jim Whartenby]

I have this Love Temperature controller that was built in the mid 1980s. 
 Everything seems to work OK, it measures the K type thermocouple temperature 
and you can change the set point.  The problem is there are 24 terminals on the 
back.  Four are already used, two for AC power and two for the thermocouple.  I 
have no idea which of the remaining 20 terminals can be used to control a solid 
state relay so that I can turn on or off a heating element.  I did find some 
terminals with a voltage on them but was unable to identify the switch contacts.

The controller is Model 154-712-7134-7501.

I used to have a set of Love catalogs but I threw them away about 5 years ago 
because they were not radio related.  Isn't that the way it always goes?
