HOA Keypad Display Fault Name
EF1
Pump Fault (input terminal S1)
External fault at multi-function input terminal S1.
EF2
Pump Fault (input terminal S2)
External fault at multi-function input terminal S2.
EF3
Pump Fault (input terminal S3)
External fault at multi-function input terminal S3.
EF4

EF5
Pump Fault (input terminal S5)
External fault at multi-function input terminal S5.
EF6
Pump Fault (input terminal S6)
External fault at multi-function input terminal S6.
EF7
Pump Fault (input terminal S7)
External fault at multi-function input terminal S7.
EF8 Pump Fault (input terminal S8)
External fault at multi-function input terminal S8.
Cause Possible Solution
An external device tripped an alarm
function
Remove the cause of the external fault and reset the fault.
Wiring is incorrect
• Properly connect the signal lines to the terminals assigned for external fault detection
(H1-oo = 20 to 2B).
• Reconnect the signal line.
Multi-function contact input setting is
incorrect
• Check for unused terminals set for H1-oo = 20 to 2B (External Fault).
• Change the terminal settings.
