[TRNSYS-users] Running trnsys for repetitive month

[Tim McDowell]

Using January weather for six consecutive months will have issues if you 
are using the solar radiation data from the weather file. The solar 
radiation calculations in TRNSYS are based on the hour of the year and 
if you are using the January solar data for months that are not January 
in the simulation the solar radiation data may not match when the sun is 
up with the solar calculations.
