39 of 44 © 2013 654_D - 06/13
Error Message Description
ADDRESS TAKEN ERROR
Two devices (thermostats, setpoint controls, snow melting controls) have been manually set to the same
address. The device continues to operate with this error but does not communicate with the tekmarNet
®
system.
To clear this error, select an unused tekmarNet
® address or select automatic addressing.
SNOW ZONE TAKEN ERROR
Two snow melting controls have been manually set to the same snow zone number and one of the
controls is NOT set to App Mode 090. The control continues to operate with this error.
To clear this error, select an unused snow zone number or set the App Mode to 090.
APP MODE 090 ERROR
Two snow melting controls have been manually set to the same snow zone number and both of the
controls are set to App Mode 090.
To clear this error, select an unused snow zone number or set the App Mode to anything other than
090.
TANDEM 090 ERROR
There are two Snow / Ice Sensors 090 or 094 installed in the zone and the other snow melting control’s
090 or 094 has a sensor problem. Locate the other snow melting control and navigate to the Toolbox
menu to determine and correct the problem. The control continues to operate with this error.
DEVICE LIMIT
More than 24 devices (thermostats or setpoint controls) have been connected to the tekmarNet ®
communication bus. To clear the error, remove and relocate devices to other available buses until the
device count is 24 or less.
OUTDOOR SENSOR SHORT CIRCUIT ERROR
Due to a short circuit, the control is unable to read the Outdoor Sensor 070. The control continues to
operate and assumes an outdoor temperature of 32°F (0°C). Energy saving features such as Warm
Weather Shut Down (WWSD) and Cold Weather Cut Out (CWCO) are disabled.
Check the outdoor sensor wire for short circuits according to the sensor installation manual. It may
be necessary to replace the outdoor sensor. Once the error has been corrected, the error message
automatically clears.
OUTDOOR SENSOR OPEN CIRCUIT ERROR
Due to an open circuit, the control is unable to read the Outdoor Sensor 070. The control continues to
operate and assumes an outdoor temperature of 32°F (0°C). Energy saving features such as Warm
Weather Shut Down (WWSD) and Cold Weather Cut Out (CWCO) are disabled.
Check the outdoor sensor wire for open circuits according to the sensor installation manual. It may
be necessary to replace the outdoor sensor. Once the error has been corrected, the error message
automatically clears.
SUPPLY SENSOR SHORT CIRCUIT ERROR
Due to a short circuit, the control is unable to read the Supply Sensor 082. When set to App Mode Boiler
or Mixing the control stops operation and does not provide any heat. When set to App Mode PWM the
control continues melting or idling but supply priority operation is not available.
Check the supply sensor wire for short circuits according to the sensor installation manual. It may
be necessary to replace the supply sensor. Once the error has been corrected, the error message
automatically clears.
