Thank you David,
<div><br>
<div>I’m not using type 56, because i have the total hourly load profile. So at first i read the loads with tipe 9 and then i consider them as input of type 690 that mimic the zone. With thermostat i control the set point temperature of the zone (20 degrees
for heating and 26 for cooling).<br>
Could it be right?</div>
<div>I made the same with fancoil instead of radiant slab and the system works.</div>

<div>Kind regards,</div>

<p>Jacopo,</p>
<p> If you are modeling the building in Type56 I would define an active layer and radiant floor in each of the apartments. I think that using Type653 might not be the best idea because presumably the apartments are all individually controlled (and may even
have different setpoints at different times). Modeling each in Type56 would allow for such control and for a better estimate of the pumping power required to feed 28 separate systems rather than one large one.</p>
<p>kind regards</p>
