[TRNSYS-users] charging and discharging - Type 10

[David BRADLEY]

Ali,

   I would recommend sending this one to your supplier's tech support 
hotline. When you do, please include the project and an indication of 
what the error message says. I'll send you a second email with the 
contact info of who you should send the question to since I have a 
pretty good idea who your supplier is... :-)

kind regards,

  David
