Hello,

I successfully applied 2 VRF with DOAS Measures (developed by @David Goldwasser) to my models, but both of them fail immediately after simulation start.

The first VRF with DOAS Measure has errors (you can find error file here) related to the part load ratio:

Cooling Energy Input Ratio Modifier Function of Low Part-Load Ratio Curve Name = AIR CONDITIONER VARIABLE *REFRIGERANT FLOW 1 COOLINGEIRLOWPLR has out of range value. * ~~~ * ...Curve minimum value of X = 0.500 must be <= Minimum Heat Pump Part-Load Ratio = 0.250.*

The second ZEDG VRF with DOAS Measure has a severe error (find the error file here):

[ZoneHVAC:TerminalUnit:VariableRefrigerantFlow][VRF Terminal Unit 1][maximum_outdoor_dry_bulb_temperature_for_supplemental_heater_operation] - Value type "string" for input "NaN" not permitted by 'type' constraint.

Please message me, If anybody can run this Measure successfully or had this problem before and could solve it.
