If your Tekmar Controller displays a 'NO HEAT ALERT', it means there has been no change in supply temperature within the specified period of time.
What to do if my Tekmar 284 shows a BOILER SUPPLY SENSOR ERROR?
If your Tekmar Controller displays a 'BOILER SUPPLY SENSOR ERROR', it means the control couldn't read the boiler supply sensor due to an open or short circuit. To resolve this, check the boiler supply sensor and its wiring.
What to do if my Tekmar 284 Controller shows a BOILER RETURN SENSOR ERROR?
If your Tekmar Controller displays a 'BOILER RETURN SENSOR ERROR', it means the control couldn't read the boiler return sensor due to an open or short circuit. To resolve this, check the boiler return sensor and its wiring.
What to do if my Tekmar 284 displays a DHW SENSOR ERROR?
If your Tekmar Controller displays a 'DHW SENSOR ERROR', it means the control couldn't read the DHW sensor because of an open or short circuit. To fix this, check the DHW sensor and its wiring.
What to do if my Tekmar Controller shows an OUTDOOR SENSOR ERROR?
If your Tekmar Controller displays an 'OUTDOOR SENSOR ERROR', the control was unable to read the outdoor sensor due to an open or short circuit. You should check the outdoor sensor and its wiring.
What does BOILER (#) OUTLET SENSOR MAXIMUM EXCEEDED mean on my Tekmar Controller?
If the Tekmar Controller shows 'BOILER (#) OUTLET SENSOR MAXIMUM EXCEEDED', the boiler (#) outlet temperature exceeds the maximum output setting.
What does 'tekmarNet® DUPLICATE SCHEDULE MASTER ERROR' mean on my Tekmar 284 Controller?
If your Tekmar Controller displays 'tekmarNet® DUPLICATE SCHEDULE MASTER ERROR', it indicates a duplicate master schedule was detected on the TN4 BUS.
What to do if my Tekmar 284 displays tekmarNet® SCHEDULE MEMBER ERROR?
If your Tekmar Controller displays 'tekmarNet® SCHEDULE MEMBER ERROR', check the schedule master wiring and the schedule master address on the TN4 BUS.
What to do if my Tekmar Controller displays FLOW PROOF CALL ERROR?
If your Tekmar Controller displays a 'FLOW PROOF CALL ERROR', you should check the flow proving device and its wiring.
