[EnergyPlus_Support] LowTemperatureRadiant: Error "Temperature out of range" ?



Dear Community,

i keep getting an error message (see below) in my GHE-GSHP-LowTemperatureRadiant:ConstantFlow setup. The glycol temp (water) seems to get to high / to low. My assumption is that the low temperature radiant system is not powerful enough to deliver the required loads that occur in the zone. But what to I have to change?

Thanks for any hints,

Arno
