It looks as though you are passing some incorrect variables back
to the building model and that the variables you are passing
(T_HEATING, T_COOLING, and RH_COOLING) are defined in the building
but aren't actually implemented in your zone. The inputs that you
need to pass from the furnace model to the building model are the
furnace's outlet air temperature, RH, and flow rate. You will need
to open TRNBuild and define a VENTILATION type in your zone. A
couple hints:<br>
<br>
1. Specify that you are going to provide air flow rate as a mass
flow and change the flow rate from a constant value (the default) to
an input. Give the input a name like MVNT_55FC41<br>
2. Specify that you are going to provide the temperature of the
ventilation air as an input. Give the input a name like TVNT_55FC41.<br>
3. Specify that you are going to provide the humidity of the
ventilation air as an input and as an RH (which is the default).
Give the input a name like RHVNT_55FC41.<br>
<br>
When Type56 talks about ventilation, it means a stream of air, not
necessarily the zone's fresh or outdoor air as is sometimes
traditional in the US.<br>

<br>
I created a type-56 3D model for a zone, and I introduced the type
108 thermostat to monitor the temperature in the zone with the
help of fan, furnace and auxiliary cooling unit, and I need little
help to figure what I am doing wrong I attached my model with this
email.<br>
<br>
Thank you very much in advance <br>
