I am modelling for LEED baseline system 8.
When I tried to implement Chilled-Water Design Supply Temperature Reset in HVACTemplate:Plant:ChilledWaterPlant, I got following error.
** Severe ** FindRootSimpleController: Controller error for controller = "A_LZ_SYS COOLING COIL CONTROLLER"
** ~~~ ** Environment=ANNUAL, at Simulation time=01/04 05:40 - 05:50
** ~~~ ** Controller function is inconsistent with user specified controller action = Reverse action
** ~~~ ** Actuator will be set to maximum action
** ~~~ ** Controller control type=Temperature and humidity ratio
** ~~~ ** Controller temperature setpoint = 9.64 [C]
** ~~~ ** Controller sensed temperature = 12.02 [C]
** ~~~ ** Controller humidity ratio setpoint = 1.09E-002 [kg-H2O/kg-air]
** ~~~ ** Controller sensed humidity ratio = 6.46E-003 [kg-H2O/kg-air]
** ~~~ ** Controller actuator mass flow rate set to 165.08 [kg/s]
Referring to other post , I tried to debug it. However, I don't know how Controller temperature setpoint and Controller sensed temperature are calculated which makes debug difficult.
Can anyone tell me any document or pages which is explaining how these two are different and calculated?
