HI,
for the sever errow check the template, where the Dual Set Point With Dead Band is definded and insure that the heating temperature is set to a lower or simular level as the cooling temperature (THeat< TCool).
It is contra productiv to heat a zone e.g. to 24 °C and cool to e.g. 22°C, this would means that the system would have to heat and cool in the same time.
For this warning (World Coordinate System selected ) try to set the coordinate system to relativ in the template Thermal Zones and Geometry: Global Geomety rules ==> relativ (i do that in my idf).
hope this will help,
best Marie
