[EnergyPlus_Support] V.1.2.2. & SolarCollectorsLowTempRadFloor.idf

Hello,

 

Some time ago "Ingdallolio" user submitted to the "problem area" the file
"SolarCollectorsLowTempRadFloor.idf". This file used to work fine with e+
v.1.2.1. but it doesn't work any more with the new version. This was a very
interesting model because with two water heaters (in series) we could
achieve effective energy storage 
(in the first tank the temperature could go above the setpoint) while
assuring  the temperature setpoint in the second tank (when there is no
energy storage).

 

 

Can anybody help me? Thanks in advance.

 

The SolarCollectorsLowTempRadFloor.err contains:
