[TRNSYS-users] TRNSYS-users Digest, Vol 29, Issue 36

[Michele Liziero]

Dear Mr. Chehal,
I think that the problem can be in the fact that if the room have a Tint
fixed to 26°C, your equation don't consider this case. Perhaps is sufficient
to change the equation in the following form:

Output = lt(time,2880)*16735 + ge(time,2881)*le(time,6552)*(
lt(Tint,26)*16735+ge(Tint,26)*33470 ) + gt(time,6553)*16735
Hoping to be helpful I wish you success in your work anyway,
Best regards,
Michele Liziero
