What to do if ZIEHL TR1200 Thermostat shows error code 8Er88?
If the ZIEHL Thermostat displays error code 8Er88, this indicates an internal device malfunction. First, switch the unit off and then back on. If the error persists, the unit needs to be returned to the factory for repair.
What to do if ZIEHL Thermostat displays error code 8Er98?
If the ZIEHL Thermostat displays error code 8Er98, this indicates an invalid parameter. To resolve this, press the "SET" button for 10 seconds while switching on the supply voltage to reset to factory settings.
How to unlock parameter configuration on ZIEHL TR1200?
If the ZIEHL Thermostat's parameter configuration is not allowed, it's likely that the code lock is active. This feature protects against settings manipulation. If you've forgotten the PIN, perform a code reset by pressing the "SET" button for 2 seconds while switching on the supply voltage. The display will cycle through 88888 – 8Cod8 – 8off8 – 88888. Release the "SET" button to set the code to OFF, with PIN = 504.
What to do if ZIEHL Thermostat displays error code 8Er18?
If the ZIEHL Thermostat displays error code 8Er18, it indicates a sensor or line short circuit. The error LED will illuminate, and the LED of the corresponding sensor will flash. You should check the sensors, wires, and terminals to identify and fix the short circuit.
What to do if ZIEHL Thermostat displays error code 8Er28?
If the ZIEHL Thermostat displays error code 8Er28, it indicates a sensor or line interruption. The error LED will illuminate, and the LED of the corresponding sensor will flash. Check the sensors, wires, and terminals to locate and fix the interruption.
What does error code 8-EE8 mean on ZIEHL TR1200 Thermostat?
If the ZIEHL Thermostat displays error code 8-EE8, it indicates an under range condition where the resistance is between 15 and 18.39 ?. Check the sensor and line resistance compensation.
What does error code 8EEE8 mean on ZIEHL TR1200?
If the ZIEHL Thermostat displays error code 8EEE8, it indicates an over range condition where the resistance is between 390.26 and 400 ?. Check the sensor and line resistance compensation.
Why my ZIEHL TR1200 showing wrong temperature values?
If your ZIEHL Thermostat shows wrong temperature values, it might be due to interchanged sensors using the 3-wire technique. Check the sensors, noting that terminals for sensor 1…6 are not compatible with terminals for sensor 7…12.
