If you have a model that is working with an air cooled condenser and you would like to switch the condenser to be water cooled for your ASHRAE 90.1 App G, first create a condenser water loop (it will be green) and THEN change the condenser of the chiller. eQuest wants you to do things in a specific order.<div>
<br></div><div>Your heating is likely 0 because you need to specify a supply air temperature for heating. Depending on the air-system you have selected, you need to input an upper supply air temperature setpoint (like 105 F) and a reheat temperature range, like 40 F. If you do not specify a temperature range, zone-level heating elements will not be sized on simulation and therefore, not turn on, resulting in no-heating.</div>
