What does “bt” mean on the R47?
-Box Temperature, which is the temperature of the PMCR module. No longer used for anything and has been eliminated on the new remotes. The EGT cutback (over temperature cutback) is not working. – On some of the older remotes, when changing the maximum exhaust temperature for the over temperature cutback, you need to press and hold the gray button until it says “SAUE” (for SAVE). Sometimes it flashes the SAVE real quick, which is normal. The Power digit on my R37 (remote without gauges) sometimes flashes. -If you are not using a thermocouple (temperature sensor) the red and yellow wires of the PMCR need to be connected together. If they are not, then it could cause a false temperature reading, which will cause the EGT cutback to go into effect. On the R37 (remote without gauges) the Power digit will blink when the EGT cutback is in effect.
