TEC220x-2 Series Non-Programmable LONWORKS®
Network Configurable Staged Thermostats
Application Requirements
The TEC220x-2 Series Non-Programmable
LONWORKS® Network Configurable Staged
Thermostats are specifically designed for single-stage
and multi-stage control of heating/cooling equipment,
such as rooftop and heat pump units.
Code No. LIT-1201911 www.johnsoncontrols.com
Software Release 1.0
Accurate temperature control is achieved with a time
proportional control algorithm, which virtually
eliminates the temperature offset associated with
traditional, differential-based thermostats. For more
advanced applications, an economizer control logic
has been integrated onto the thermostat for use with
proportional damper economizer actuators.
All programmable models contain a Single-Pole
Single-Throw (SPST) auxiliary switch, which can be
used to control lighting or disable the economizer
function.
Mechanical Installation
Location
Install away from any heat source.
Do not install the thermostat:
•on an outside wall
•near an air discharge grill
•in a location affected by direct sun radiation
•in an area that restrains vertical air circulation to
the thermostat

Installation
To install the thermostat:
Note: Wall surface must be flat and clean.
1. Remove security screw on the bottom of
thermostat cover.
2. Open up by pulling on the bottom side of
thermostat (Figure 1).
3. Swing the thermostat circuit board to the left by
pressing the pull tabs (Figure 2).
4. Pull cables 6” out of the wall.
5. Insert cable in the central hole of the base.
6. Align the base and mark the location of the two
mounting holes on the wall. Install proper side of
base up.
mountingbase
Figure 2: Pull Tabs
7. Install anchors in the wall.
8. Insert screws in mounting holes on each side of
the base (Figure 2).
9. Gently swing the circuit board back on the base
and push until the tabs lock.
10. Pull out the screw terminal blocks using the pull
tabs on each connector (Figure 3).
11. Strip each wire 1/4 inch.
12. Insert each wire according to wiring diagram.
13. Gently push excess wiring back into the hole.
14. Install wiring terminals.
15. Reinstall the cover (top side first) and gently push
extra wire length back in the hole in the wall.
16. Install security screw.

Caution
•If replacing an old thermostat, label the wires
before removal of the old thermostat.
•Electronic controls are static sensitive devices.
Discharge yourself properly before installing the
thermostat.
•Short circuits or incorrect wiring may permanently
damage the thermostat or the equipment.
•Anti-short cycling can be set to 0 minutes for
equipment that possesses its own anti-cycling
timer. Do not use that value unless the equipment
is equipped with such internal timer. Failure to do
so can damage the equipment.
•All Thermostat devices are to be used only as
operating controls. Whenever a control failure
could lead to personal injury and/or loss of
property, it becomes the responsibility of the user
to add safety devices and/or alarm system to
protect against such catastrophic failures.
Wiring
If the same power source is used for the heating
stages, install jumper across RC and RH. Maximum
current is 2.0 amperes.
If auxiliary output is used to toggle occupancy of the
electronic control card inside the equipment, configure
the relay parameter (Aux cont ) to the Normally Open
(N.O.) setting. A second relay can be added for
additional functionality of the occupancy output.
Economizer output uses a half bridge rectifier.
Reference of the control signal is the common of the
power supply of the thermostat, terminal C.
Electromechanical contacts are to be used with the
digital inputs. Electronic triacs cannot be used as
mean of switching for the input. The switched leg to
the input is terminal C (common)
The transformer of the unit provides power to the
thermostat and the additional loads that are wired to
the thermostat.
Electrical Installation
Planning and Selecting Cables
Plan the placement of cables for inputs, outputs,
communication, and power.
Place input, output, power, and network cables to
avoid the effects of ambient noise.
Separate analog type cables for power,
communication, inputs, and outputs from other types
of cables.
Connectors
The board connectors accept wires or flat cables:
22-12 AWG (0.14-2.5 mm²) per pole.
