LSI thermostat stage settings trouble!

Hey ive got LSI electric furnace that has a lsi thermostat controlling it. Furnace is from 1974 my problem is the old thermostat has slider settings that slide around the dial inside. One slide is for stage one the other is for stage 2. the numbers on the dial range from .15 to 1.0. My question is what should stage one slider be set on and what should stage 2 slider be set on...please help me if possible

those are your heat anticipation settings for the stages...go down on the gas valve with a flashlight and magnify glass you should see .## stage one .## stage two,slide the brass pins on or near the decimal values.......they don't control the temperatures like the actual temp settings ,but do effect it reacting when the room reaches your degree settings.
