Re: [TRNSYS-users] Problems with Cooling Type Manager/Maximum above temperature

Ole,

You can set the setpoint as an INPUT and do whatever you'd like at that 
point (forcing function, equation, etc.).  Or you can use the simpler 
form of that equation:

Tset = -75*SCHED +99

So when SCHED = 1 it's equal to 24 and when SCHED=0 it's equal to 99.
