[TRNSYS-users] floor heating temperature set-point value

Wang,
  There are a number of possible explanations: the gains in your space 
could be assisting the space to warm up faster but then could act to 
maintain the building at its higher temperature (causing it to cool down 
more slowly). alternatively, perhaps your system is set up so that it 
runs a pump with warm water through the floors to heat up the space 
actively but then only shuts the pump off when it wants the space to 
cool back down (ie active heating but passive cooling) then that could 
cause the different time constant that you are seeing.
Regards,
  David
