North American emissions
compliance
United States
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in
a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and
receiver.
Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV
technician for help.
Canada
This Class (B) digital apparatus meets all the requirements
of the Canadian Interference-Causing Equipment
Regulations.
Cet appareil numérique de la Classe (B) respecte toutes
les exigences du Règlement sur le matériel brouilleur du
Canada.
Parts included
One TEC3000 Series Thermostat Controller with integral
mounting base
One installation instructions sheet
Location considerations
For networked models, locate the TEC3000 Series
Thermostat Controller:
On a partitioning wall, approximately 5 ft (1.5 m) above
the floor in a location of average temperature, to allow
for vertical air circulation to the TEC
Away from direct sunlight, radiant heat, outside walls,
outside doors, air discharge grills, stairwells, and from
behind doors
Away from steam or water pipes, warm air stacks,
unconditioned areas (not heated or cooled), or sources
of electrical interference
In a clear path between the integrated passive infrared
(PIR) occupancy sensor, if equipped and the space it
monitors
For wireless models, also locate the thermostat controller:
Outside of a recessed area, metal enclosure, or shelving
unit
On the same building level as the other wireless devices
on the same personal area network (PAN)
At least 2 in. (51 mm) away from any metal obstruction
In the direct line of sight to other wireless devices on
the same PAN. Signal transmission is best if the path
between the TEC3000 and other wireless devices is
direct as possible. Line of sight is desirable but not
required. See Table 1 and Table 2 for the recommended
and maximum distances.
Away from metal and large solid obstructions, that
includes equipment rooms and elevator shafts and
concrete or brick walls, between the TEC3000 and
the ZFR182x or ZFR183x Router/Repeater or ZFR Pro
Coordinator Radio
Within range of two or more wireless devices on the
same PAN. Redundancy in the layout provides the best
reliability in wireless installations
At least 20 ft (6 m) from a microwave oven
For integrated PIR models, make sure that the thermostat
controller is located centrally, where occupant movement
is frequent. Ensure that the unit is not blocked by a plastic
tamper resistant enclosure (such as the GRD10A-608). The
plastic enclosure blocks the occupancy sensing capability.
The use of insulating foam pads is necessary for
installations where wiring passes through the wall to the
thermostat.
For wireless models, the effective transmission range and
distance for indoor applications vary because of wireless
signal absorption and reflection due to metal obstructions,
walls or floors, and furniture that is found in building
interiors.

    What to do if my Johnson Controls Thermostat displays Cooling/Heating Unavailable due to Changeover?
    • R
      Robert RichardsonAug 25, 2025
      If your Johnson Controls Thermostat displays 'Idle' with a 'Cooling Unavailable' or 'Heating Unavailable' status, and your system uses a two-pipe fan coil/VAV, first check the wiring of the supply temperature sensor/switch. Then, verify that the changeover is set up correctly for the type of sensor attached (sensor or switch). Also make sure that the supply is not in heating/cooling mode. Finally, check the placement of the supply temperature sensor or switch.

    How to fix rapid cycling with PID on my Johnson Controls Thermostat?
    • K
      Kathryn LeeAug 26, 2025
      If the staged equipment cycles too rapidly or slowly on your Johnson Controls Thermostat when the PID is running, it may be due to the control band around the setpoint being set incorrectly. Verify that the equipment's minimum on/off times are set correctly. If the default deadband doesn't provide the required temperature control, set 'Temp Control Setup' to 'Deadband Override' and adjust the 'Deadband' parameter to your preferred value.

      Danielle EllisAug 26, 2025
      To resolve a 'Firmware Mismatch' on your Johnson Controls Thermostat: First, upgrade the TEC3000 to the latest released version. Then, upgrade the TEC3000 to the current version again. If the previous downgrade has not completed because the previous version is no longer supported, reboot the TEC3000 to clear the fault.

    What to do if dehumidification is unavailable on my Johnson Controls Thermostat?
    • C
      Corey DiazAug 29, 2025
      If your Johnson Controls Thermostat shows 'Dehum Unavailable', and the zone humidity source was a BAS, check the BAS to ensure it's online and providing the humidity reading to the TEC. If you intentionally removed the BAS mapping, reset the sensors through the menu. If the problem persists, order replacement units and return the affected devices to Johnson Controls under the RMA program.
