Dear Doreen,

did you paste part of your control file text or is this the only text in it? 
Recent control files seem to have a tag on the top specifying the "domain" of 
the control and the number of control functions. For example, you file should 
start like this: 

example.ctl
* Building
comment for control file. This one uses external imported setpoints.
   1  # No. of functions
* Control function
# senses the temperature of the current zone.
    0    0    0    0  # sensor data
# actuates air point of the current zone
    0    0    0  # actuator data

...and ends with the same way as you have it. Add the first few lines (in case 
you do not have them) and try it again.
ESP-r vers. 11.5 that came out a few weeks ago (11.4 is not the latest) allows 
you to import (for the basic control only) both heating and cooling control 
setpoints from external files.

Regards,
Georgios
