Hello Mehdi,<br><br>you can use a forcing function for "cooling control signal" wich is one when your system are in summer period and 0 in winter; and another forcing function for "winter control signal ". You have to use an equation wich combine this control signal with the temperature control signal. If you want i can send you an example.<br>

Hello everybody<br>
<br>
My project has two main parts, first cooling coil and the second heating coil. I want to run the cooling coil in summer and heating coil in winter.<br>
<br>
As far as I know, start and stop run time in “control card” are applicable to all equipment but I need to run cooling part in summer and heating parts in winter.<br>
I was wondering if any body could give me some hint to solve the issue.<br>
<br>
Regards<br>
Mehdi<br>
