idealAir HVAC system question, supply temperature

I’m trying to create a simple HVAC system in honeybee that would emulate a central AHU system with sensible and latent heat recovery and a supply air-temp that would heat the air up to 19C(constant). The zones have a heating setpoint at 21C and I want to use Ideal heaters in the zones.
I tried to set the IdealAir component parameter, heat_temp, to 19, but that doesnt seem to be the right parameter.
Will I have to use IronBug for this, or can I use another component with a template?
