I am trying to simulate CentralHeatPumpSystem with a geothermal loop. The hourly results indicate no flow through the geothermal loop (source). Could you hint what might be going wrong. Here are "some" of the errors I am getting:
** Warning ** Capacity ratio as a function of temperature curve output is not equal to 1.0
** ~~~ ** (+ or - 10%) at reference conditions for ChillerHeaterPerformance:Electric:EIR= CO2CHILLERHEATERPERF
** ~~~ ** Curve output at reference conditions = 1.166
** Severe ** CalcChillerHeaterModel: ChillerHeaterPerformance:Electric:EIR="CO2CHILLERHEATERPERF", DeltaTemp < 0
** ~~~ ** Reference Simultaneous Cooling-Heating Mode Leaving Condenser Water Temperature [60.0]
** ~~~ ** is below condenser inlet temperature of [81.8].
** ~~~ ** During Warmup, Environment=WINTER DESIGN DAY IN OC, at Simulation time=01/15 00:00 - 00:10
** ~~~ ** Reset reference temperature to one greater than the inlet temperature
** Severe ** FindRootSimpleController: Controller error for controller = "MAU1 AHU COOLING COIL CONTROLLER"
** ~~~ ** Environment=OC, at Simulation time=01/01 07:00 - 07:01
** ~~~ ** Controller function is inconsistent with user specified controller action = "" action
** ~~~ ** Actuator will be set to maximum action
** ~~~ ** Controller control type=Temperature
** ~~~ ** Controller temperature setpoint = 7.00 [C]
** ~~~ ** Controller sensed temperature = 11.79 [C]
** ~~~ ** Controller actuator mass flow rate set to 6.20 [kg/s]
** ~~~ ** Controller actuator temperature = 11.39 [C]
************* ** Severe ** ChillerHeaterPerformance:Electric:EIR="CO2CHILLERHEATERPERF": Reference temperature problems continue.
************* ** ~~~ **
