Re: [TRNSYS-users] Differential controller(Temperature controller)

[David BRADLEY <d.bradley@tess-inc.com>]

Nipaporn,
  If you want a heating controller (ie a controller that turns equipment on when the room temperature falls below 26.5C and allows it to stay on until room temperature reaches 27.5C) then set the first input to the middle of your set point temperature range (27C). The second input will be the temperature that you are monitoring (the room temperature). The fifth input (upper dead band) would be set to 0.5C and the sixth input (lower dead band) would be set to -0.5C.

  If you want a cooling controller (ie a controller that turns equipment on when the room temperature rises above 27.5C and allows it to stay on until room temperature falls to 26.5C) then set the second input to the middle of your set point temperature range (27C). The first input will be the temperature that you are monitoring (the room temperature). The fifth input (upper dead band) would be set to 0.5C and the sixth input (lower dead band) would be set to -0.5C.

Kind regards,
 David

Hi TRNSYS users,
I need some help about differential controller(Type2b). I would like to control temperature in the room within 26.5-27.5oC. How can I define the upper/lower deadbands (Upper input temperature Th, Lower input temperatureTl, Monitoring temperature Tin, Upper dead band dT, Lower dead band dT)to monitor the room temperature to gain simple ON/OFF control.
 
Thank you in advance.
Nipaporn
