This is accomplished by a reverse approach. Set the heating or cooling
air setpoint temperature with type 56 as an input. Then, you can use
an equation in the dck to calculate this variable setpoint temperature
(e.g. the air temperature required to achieve your operative
temperature setpoint, based on the current mean radiant temperature).<br>

how to solve this is by using a type (controller, type 2 or thermostat,

connected to this type (e.g. 2b and creating a schedule elsewhere, in
an equation solver), and the heating must be defined as a limited power
connected to an input, which is then the output of the control type
(type 2 or type 8).</font></div>

<br>
The simplified heating and cooling in Trnbuild is now comparing the zone<br>
AIR temperature with the given set points. Is there a way to change<br>
this (or another controller model) to have the zone OPERATIVE<br>
temperature compared with the set points?<br>
