Michael,

As David says, control can be achieved by external control. But there is 
also another option to avoid short run periods avoiding programming. In 
this case, you could use a type 2 controller. this controller provides a 
histeresis-type control so short run periods could be avoided with the 
appropiate histeresis parameters.

Best Regards

Hello,
I would like to have an information about the use of water to water heat 
pump type 668 from tess and all trnsys and tess heat pumps generally.
How can I set a minimum time value of run and a minimum time value of 
stand-off to prevent short cycle.
Best regards
Michel  PAUL
