ER04
Illegal setup values used:
COOL is
used for OUT2 when DIRT (cooling
action) is used for OUT1,
or when PID mode is not used for
OUT1 (PB =0 and/or TI=0)
Check and correct setup values of OUT2, PB1, PB2,
TI1, TI2 and OUT1. IF OUT2 is needed for cooling
control, the controller should use PID mode (PB
≠
0
and TI
≠
0) and OUT1 should use reverse mode
(heating action), otherwise, OUT2 cannot be used for
cooling control

Event Input Error:
Two or more
event inputs are set to the same
function
Do not set the same function in two or more Event
Input Function parameters (E1FN through E6FN)

ATER
Auto-Tuning Error:
Failed to perform
Auto-Tuning function
1. The PID values obtained after Auto-Tuning
process are out of range. Retry Auto-Tuning.
2. Do not change the setpoint value during Auto-
Tuning process.
3. Use manual tuning instead of Auto-Tuning
process.
4. Do not set a zero value for TI.
5. Do not set a zero value for PB.
6. Touch RESET key
