Hi trnsys users
I have a new problem. :)
I m heating a greenhouse with a heat pump.I m currently trying to control
this heat pump. I want to work this heat pump when temperature is below 8
degree and stop that heat pump when temperature rises 8 degree in the
greenhouse. To make it I used five stage room thermostat. I connected
grenhouse temp to monitoring temperature of thermostat and entered 8 degree
value for 1 stage heating setpoint. But I got this error messagas in the
figure.
I connected control signal for 1 st stage heating in the thermostat to fan
coil and heat pump as you see in the picture.
Now how can ı control to start and stop of this heat pump as I
want. Because I don't want this heat pump to work for 24 hours. I tried the
differentual equation control but I got the same error messages.
I added also my deck file.
Please help me.
Thanks
Regards
