An incorrect device has been connected to the tekmar Net TM tN1/tN2 input terminal. An RTU has
been connected to the control and either the Heating Curve/Reset Ratio DIP switch has been set to
Reset Ratio or the control is in Mode —2—. Once the problem has been corrected, press either the
Menu or Item button to clear the error message from the control.
A short circuit has been read between the tekmar Net TM tN1 / tN2 terminal and a Com terminal on the
control. Either the wires leading to the tekmar NetTM tN1 / tN2 device are shorted or the polarity of
the wires is reversed. Determine the cause and remove the short. The error message can be cleared
by pressing either the Menu or Item button.
The control is no longer able to read the information that is coming from the RTU. Reconnect the RTU
and press either the Menu or Item button to clear the error. If the RTU has been deliberately disconnected

to clear the error message.
The control is no longer able to read the Outdoor sensor due to a short circuit. In this case the control

as described in the Data Brochure D 070. To clear the error message from the control after the sensor
has been repaired, press either the Menu or Item button.
