Parameter Description
Operating Mode:
Default
Utilizes factory set operating variables that provides a balance of water and energy
savings. See Table 12. Operating Mode Parameters for more information.
Operating Mode:
Energy Saver
Energy Saver mode will enter adiabatic operation more quickly than Default or
Water Saver Operating Modes resulting in lower fan power energy consumption.
See Table 12. Operating Mode Parameters for more information.
Operating Mode: Water
Saver
Water Saver mode will stay in dry operation longer than Default or Energy Saver
Operating Modes resulting in lower water consumption. See Table 12. Operating
Mode Parameters for more information.
Signal Type
Defines the type of input signal. This can be set to either 4-20mA, 0-10V, 10-0V or
BMS 0-100%. The current signal is supplied to input card EL3014 channel 2 or
contacts X7:27 and X7:28. The voltage signal is supplied to input card EL3174
channel 1 or cont acts X7:17 and X7:18. The BMS signal refers to the “CIFanCMD”
variable in Table 65. BMS Communication Points List
Leaving Fluid Temp
Setpoint
Set-point for the fluid outlet temperature
Control Range
Allowed offset in leaving fluid temperature set point before changing
stages/operating modes. For example, allows leaving fluid temperature to rise
above leaving fluid temp setpoint by this control range before changing to adiabatic
mode.
Adiabatic Switchpoint
Ambient temperature at which adiabatic operation becomes possible. See
Adiabatic
Switchpoint
on Page 13 for more details.
Run Authorization Type
Source signal to switch the unit between stand-by and active. This can be set to
either HMI, digital input or BMS. HMI refers to the button on the top left of the
screen, digital input refers to input card EL1008 channel 6 or contacts X5:7 and
X5:8 on the terminal strip, BMS refers to the “BMSrunEn” variable in Table 65. BMS
Communication Points List . The HMI button is always taken into account to
enable the unit to run (also when the type is set to digital input or BMS).
