Hi,

I am modeling a building with dual heating source. The RTU system has a
furnace which heats the air to the required temperature. Once the
temperature is achieved, further the electric reheat coils are used to
maintain the temperature.

Also during the unoccupied hours the gas furnace is used to maintain the
temperature in the rooms.

In eQuest we can define two heat source under the heating tab (i.e. heat
source & Zone heat source). Can anyone guide me on which source should be
selected for Gas heating and which one for the electric reheat coils?

I presume that the furnace should be used as the heat source and electric
reheat coil for zone heat source. Kindly guide me so as to move ahead with
the simulation.

Regards,

Aditya
