Error Message Description

BUS ERROR

Due to an open or short circuit, communication is lost with the tN4 bus. Check the wires for damage

or loose connections. Check the wires for continuity. The error message will clear once the error

condition has been corrected.

Note: In some cases, the setpoint control is intentionally removed from the tN4 system. Press the

Up and Down buttons together to clear the address

and set Dip 2 to the ‘None’ position. This will

also clear the bus error message.

NO tN4 SYSTEM CONTROL

DIP switch 2 is set to tN4 System Control and the setpoint control does not detect the tN4 System

Control. Once the tN4 System Control is detected, this error will clear automatically.

Note: If a tN4 System Control is not installed, set the tN4 System Control DIP switch 2 to None.

ADDRESS ERROR

Two tN4 devices have been manually set to the same address. The setpoint control continues to

operate with this error but does not communicate with the tN4 bus. To clear this error, manually

select an unused address. This can be done automatically by setting the Address item to Auto.

DEVICE LIMIT

There are more than 24 devices on the tN4 bus. The additional devices must be removed and

reconnected to a different tN4 bus if possible.
