tN4 BUS ERROR
Due to a short or open circuit, communication is lost with the tN4 bus. Check wires for damage.
Check ‘C’ and ‘R’ wires for polarity. All devices on the tN4 bus will display this error if there is a
short circuit. If the error is only on this device, check for an open circuit between the thermostat
and Zone Manager. Once the error is corrected press any button to clear the error.
NO tN4 SYSTEM CONTROL
The tN4 System Control DIP switch is set to tN4 System Control and the thermostat 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 to
None.
ADDRESS ERROR
Two thermostats have been manually set to the same address. The thermostat continues to
operate with this error but does not communicate with the tN4 bus. To clear this error select
an unused address. This can be done automatically by setting the Address item to Auto.
DEVICE LIMIT
You have installed more than 24 devices on the tN4 bus. You must remove the additional
devices and move them to a different bus if possible.
