[EnergyPlus_Support] Re: How do I override a temperature sensor?



It shows the OAT going up by 6 degrees each time step:
SETOAT,Line 1,SET OAT_ACTUATOR = OAT_SENSOR + 6,1.400000, 
SETOAT,Line 1,SET OAT_ACTUATOR = OAT_SENSOR + 6,7.400000,
SETOAT,Line 1,SET OAT_ACTUATOR = OAT_SENSOR + 6,13.400000,

The simulation ends when the OAT reaches the toasties 421.4 deg C. :-)

Evidently when I read the OAT I'm not reading the original value from the weather file, but the already increased one.

Thanks for your help
