Noticed that the arm power in the TCS simulation model were way low. I increased the x-arm (H1:TCS-SIM_XARM_POWER_WATTS_PER_INPUT_UNIT) and y-arm (H1:TCS-SIM_YARM_POWER_WATTS_PER_INPUT_UNIT) calibration factors from 4.32 to 7.21 and from 4.09 to 6.62, respectively.
The simulation isn't useful yet, since it assume central CO2 heating.
