RE: Re: [EnergyPlus_Support] EMS actuator causing fatal error in V8.1

Dear Jean,

Thank you for your reply.

The edd file was the first thing I checked but found no trace of the "Zone Temperature Control" actuator. I've double checked the variable names and they are all matching.

The strange thing is that the edd file shows the calculated value during warmup for the SET statement containing this actuator/variable in the line traces.

To make sure that this is a problem with the V8.1 version only, I checked the edd file for V8.0 of the idf file (the one I updated to V8.1) and indeed found the following two actuators available:

EnergyManagementSystem:Actuator Available,PDEC,Zone Temperature Control,Heating Setpoint,[C]

EnergyManagementSystem:Actuator Available,PDEC,Zone Temperature Control,Cooling Setpoint,[C]

Any Idea why this is happening?

Check the edd file to see if that variable name is still correct. If you don't have an edd file you need to still code in the "verbose" statements into your code.

Hi all,

Using release V7.0, I setup a "Zone Temperature Control" actuator with "Cooling Setpoint" as its control type to control the setpoints of a zone with an ILAS (my setpoints change with every timestep and these in turn depend on values in a Schedule:File in case you're wondering why I'm using this actuator in the first place). There were no severe errors or warnings in the results. I've been converting the exact same idf file to work with every new release ever since including V8.0 and was having no problems. However, when converting to V8.1 I got the following fatal error:

   ** Severe  ** Invalid Actuated Component Type =ZONE TEMPERATURE CONTROL
   **   ~~~   ** Entered in EnergyManagementSystem:Actuator=PDEC_ZN_SP

   ************* EnergyPlus Sizing Error Summary. During Sizing: 0 Warning; 0 Severe Errors.
   ************* EnergyPlus Terminated--Fatal Error Detected. 0 Warning; 3 Severe Errors; Elapsed Time=00hr 00min  1.48sec

I've checked the "Addressed Issues" of release V8.1 to see whether this actuator has been renamed or replaced but found neither to be the case.

Is this a Bug in V8.1 or am I missing something here?

Your help is much appreciated.
