Hello Metkel,

you have to utilize the greater than and less than function GT/LT in the right way.

GT(Tamb,18)+LT(Tamb,14)*2

è 0 no mode

è 1 cooling mode

è 2 heating mode

Mit freundlichen Grüßen / Kind Regards,

Dear TRNSYS users,

Could you anyone tell me if it is possible to write an if statement in the equation box,
I am trying to send a control signal based on the outside temperature, if outside air temperature is
greater than 18 deg C then the heat pump would run in cooling mode else if the outside air temperature is less than 14 deg C then  the heat pump would run in heating mode.

Any suggestions would be appreciated thank you very much.


Regards,
Metkel
