Cause
P1-01 parameter selection is not compatible
with Geothermal Mode (b1-01 = 5).
HOA Keypad Display
TLGI Geothermal Input
Cause
The input signal level has dropped below
3 mA or risen above 21 mA when the drive
was running and b1-01 = 5, H3-0o = 21
(Geothermal Input), H3-0o = 2
(4 to 20 mA), and Q2-09 = 2 (Fault).
The drive was running while b1-01 = 5,
H3-0o≠ 21 (Geothermal Temp), and
Q2-09 = 2 (Fault).

Parameter Name
H3 Multi-Function Analog Input Settings
Full scale: Q2-02 = 10 V (or 20 mA), Q2-01 = 0 V (or 4 mA)
This input is internally limited to -999.9 °F to +999.9 °F
Disables the functionality of the programmed terminal.
Geothermal Set Error
Confirm b1-01 and P1-01 parameter settings.
Temperature Lost Geothermal Input
The geothermal input is not present.
Confirm that the device connected to the analog input terminal is installed and working properly.
Assign one of the analog inputs to "Geothermal Temperature", H3-0o = 21.
Geothermal Mode Parameters
The drive is running at the level set in Q2-03 due to an incorrect setting.
Set the temperature parameters in the following order:
Q2-08 > Q2-07 > Q2-06 > Q2-05
