Eurotherm 2116 operates on OP2 with loud relay noise, how to switch to OP1 mode?

I purchased a 2116 controller as a replacement on a box furnace. I was able to configure it to PID mode but during the heating ramp it operates on OP2 along with a loud relay click. All my other furnaces run on OP1 with a nice quiet hum when cycling. Besides this the controller still works great and holds a steady temperature.

This is my first time configuring a controller so it is possible I missed a step. The configuration passwords for my other controllers are lost so I cannot compare parameters. If you have any suggestions on how to get it cycling on OP1 instead of OP2 that would be great.
