Hi, I try to model Appendix G Baseline system 4 with OS so import the template system "Packaged Rooftop Heat Pump" as the starting point. But how to set up the control of electrical auxiliary heating coil as required by 90.1 "The system shall be controlled with multistage thermalstas and to energize auxiliary heat only on the last thermalstat stage and when outdoor air temp is less than 40F" ?
