Description
ADDRESS TAKEN ERROR
Two devices 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. The control continues to operate with this
error. To clear this error, select an unused snow zone number.
SYSTEM CONTROL LOST ERROR
The thermostat can no longer communicate to the tekmarNet system control. Check for open or short circuits in the tekmarNet
communication wiring. The error automatically clears once the tekmarNet system control has been detected. If the tekmarNet
system control was intentionally removed from the system, press the Reset button.
TANDEM SNOW/ICE SENSOR ERROR
There are two Snow / Ice Sensors installed in the zone and the tandem snow melting control 654 sensor has a 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. Press the Reset button to clear the error.
DEVICE LIMIT ERROR
More than 24 devices 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 OPEN CIRCUIT ERROR
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). Check for wiring faults and it may be necessary to replace the sensor. Once the error has been corrected, the
error message automatically clears.
OUTDOOR SENSOR SHORT CIRCUIT ERROR
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). Check for wiring faults and it may be necessary to replace the sensor. Once the error has been corrected, the
error message automatically clears.
SLAB SENSOR OPEN CIRCUIT
The control is unable to read the Slab Sensor 072 or 073. Check for wiring faults and it may be necessary to replace the slab
sensor. Once the error has been corrected, the error message automatically clears.
SLAB SENSOR SHORT CIRCUIT
The control is unable to read the Slab Sensor 072 or 073. Check the wire for faults and it may be necessary to replace the slab
sensor. Once the error has been corrected, the error message automatically clears.
SNOW SENSOR YELLOW WIRE OPEN CIRCUIT
The control is unable to read the yellow wire connected to the Snow/Ice Sensor 090 or 094 or the Snow Sensor 095. Automatic
operation is disabled but manual start is still available. Check the snow/ice sensor yellow and black wires and any wire splices
for faults. It may be necessary to replace the sensor. Once the error has been corrected, the error message automatically clears.
SNOW SENSOR BLUE WIRE OPEN CIRCUIT ERROR
Due to an open circuit, the control is unable to read the blue wire connected to the Snow/Ice Sensor 090 or 094, or the Snow
Sensor 095 on terminals 2 and 3. The control can no longer automatically detect snow or ice, but manual start of the snow
melting system is still available.
Check the snow/ice sensor or snow sensor blue and black wires and any wire splices for open circuits according to the sensor
installation manual. It may be necessary to replace the sensor. Once the error has been corrected, the error message automatically
clears.
SNOW SENSOR BROWN WIRE SHORT CIRCUIT ERROR
The control is unable to read the brown wire connected to the Snow/Ice Sensor 090 or 094. Check the snow/ice sensor brown
and black wires for faults. It may be necessary to replace the sensor. Once the error has been corrected, the error message
automatically clears.
SNOW SENSOR BROWN WIRE OPEN CIRCUIT ERROR
Due to an open circuit, the control is unable to read the brown wire connected to the Snow/Ice Sensor 090 or 094 on terminals 2
and 5. Idling and Storm is disabled and energy saving features such as Warm Weather Shut Down (WWSD) and Cold Weather
Cut Off (CWCO) are operated using the outdoor temperature only.
Check the snow/ice sensor brown and black wires for open circuits according to the sensor installation manual. It may be
necessary to replace the sensor. Once the error has been corrected, the error message automatically clears.
