Temperature reassignment problem

Dear all,
 
I would like to gradually heat my system after minimization. I tried to do this by the following settings in the conf. file (in the execution-part of the script, because I would like to do different MD-phases (with/without constraints) in 1 go):
 
# Heat to $temperature with 25K every 0.5 ps (takes 5 ps to reach 300K)
reassignTemp 50
reassignFreq 250
reassignIncr 25
reassignHold $temperature

When I look into the log-file however, I see that the temperature is reassigned to 300 K (which is the value of $temperature, set by: 'set temperature 300') instead of 50, 75, 100 and so on.
What could be the problem?
 
Thanks in advance,
Marc
