[TRNSYS-users] Auxiliary electrical zone heater

["Julien L'Hoest" <julien.lhoest@gmail.com>]

Hello,
I'm modeling a room air conditioner coupled with a type 56. The Room air 
conditioner(RAC) is equiped with an inverter so that its power is 
adjustable.
The RAC is coupled to the type 56 using a iterative feedback controler 
(type22).
The problem is that sometimes in winter the power of the RAC is 
unsufficient to satisfy the heating demand and thus the setpoint 
temperature is not reached.
I would like to add an auxiliary electrical heater which would be ON 
when the RAC power is insufficient.
However I already use a iterative controler for the RAC and only one can 
be used at once. Does anyone know how could I do to control the 
auxiliary heater ?
Thank you in advance.

Julien.
