Issue Date August 8, 2002
Introduction
Description
In this document, Building Automation System (BAS) is a generic term
that refers to the Metasys® Network (Network Control Module [NCM] or
N30 series), Companion, and Facilitator® supervisory systems. When you
refer to system specific applications, use the specific system names.
The TEC1100 Series includes three nonprogrammable models:
single-stage (TEC1101), heat pump (TEC1102), and multistage
(TEC1103). The applications include furnace, air conditioner, heat pump,
and rooftop units. The TEC1100 incorporates fuzzy logic for precise
control in a thermostat type package.
All TEC1100s have Metasys N2 communication capability. This
communication allows the user to view and adjust parameters from a
remote workstation. It also provides information, such as outdoor air
temperature, to the TEC1100 units on the bus. The thermostat is easy to
operate and normally displays room temperature and mode of operation
using Cooling ( ) or Heating ( ) icons. When there is a call for cooling,
the Snowflake icon ( ) blinks. Likewise, during a call for heating, the
Flame icon ( ) blinks. When the temperature is satisfied, neither icon
blinks. In the Auto mode, both icons ( ) appear continuously when
satisfied. Light-Emitting Diodes (LEDs) on the top of TEC1102/1103
models use Binary Inputs (BIs) to indicate a clogged filter and external
service. A unique temperature alarm (BI 2) indicates that the zone
temperature has not been satisfied in 45 minutes.

Connecting the N2 Bus
To connect the N2 Bus:
1. Observe the polarity when connecting the N2 Bus wires to the
TEC1100.
Note: Each TEC has self-terminating End-of-Line (EOL) resistors.
However, one EOL resistor is needed at the BAS (two are
preferred at opposite ends).
2. Continue this process for each TEC1100 using the daisy-chain wiring
method (Figure 9).

Setting the N2 Address
N2 Device Mapping
To set the N2 Address:
1. Push the Fan and Mode buttons simultaneously for 10 seconds after
the machine is turned on. The lower section of the display shows the
current N2 address.
2. Push the ∨ or ∧ buttons to change the address (1-253). Map the
TEC1100 into CPN/FAC/NCM/N30 series as a vendor device (VND).
3. Push any button to exit this mode, or wait 5 seconds and the TEC
automatically returns to normal operation.
Note: You can lock the keyboard using the DIP switch to prevent address
change, however, this disables access to other functions except
temporary occupancy.
When adding the TEC to the Metasys system (Person-Machine Interface
[PMI] and Companion system), you must define the TEC1100 as a Vendor
Device (VND). For the NCM, do not direct map any points. Run control
of these points through the Control System (CS) object only.
Note: For the TEC110x-0, do not use the Adjust command with the
Companion/Facilitator (CPN/FAC) system. This command is not
supported. The TEC110x-0 responds with an offline message but
continues to operate normally.

Over time, the TEC1100 learns how long it takes the system to meet the load. If the system
can change the room temperature quickly, the TEC1100 allows the thermostat to drift further
from setpoint before starting the equipment. If the system takes a longer period of time to
change the room temperature, the TEC1100 does not allow the temperature to drift as far
from setpoint. The TEC1100 also takes into account the minimum On/Off times.
The 2-minute On/Off time allows the equipment to cycle more frequently at smaller
differentials than the 4-minute On/Off time.
For multistage applications, the TEC1100 does not bring on the next stage of cooling or
heating if it knows that the system can change the temperature by 6° in one hour or 1° in
10 minutes. To verify thermostat operation, force the next stage on by changing the setpoint
by more than 2° (see the Verifying Proper Thermostat Operation section).
The TEC1100 thermostat accepts a contact closure for a clock/timer to allow the use of
alternate or setback heating and cooling setpoints in place of a BAS.
When the contact is open, the Day icon (
setpoint. When the contact is closed, the Night icon (
to the night setpoint. Pressing the Day/Night button when the thermostat is in Night mode
switches the thermostat to Day mode, even if a clock/timer is used. The Clock (CLK)
contacts on the thermostat are in parallel with the thermostat Day/Night button and changes
to the next command given by the clock. Therefore, if the thermostat is in Night mode
(contacts closed) and the thermostat is switched to the Day mode from the front panel, then
at the next clock control time, the thermostat stays in the Day mode. When the contacts
close again the following night, the thermostat switches to night setpoints.
When in Night mode, select this feature by pushing Day/Night button to put TEC1100 in
1-hour timed override to occupied setpoints.
When using a remote sensor (SEN-500-1), the TEC1100 internal sensor is disabled. If two to
six remote sensors are connected, then they can be used for temperature averaging. See the
SEN-500-1 Remote Indoor Temperature Sensor Product/Technical Bulletin (LIT-216504) for
more information.
There are two separate analog inputs on the TEC1100, which are the room sensor and a
duct or outdoor air sensor on a slave bus. The duct temperature appears when the Outdoor
button is pushed. On the TEC1101 and TEC1103, the outdoor/duct sensor is simply a
monitor of temperature. On the TEC1102, the Outdoor temperature provides a low
temperature lockout (see Displaying Outdoor/Duct Air Temperature under the
Commissioning section later in this document). Both of these can be displayed on the LCD or
at the Metasys system. The Outdoor temperature can be a global N2 Override from a single
sensor. For wiring information, refer to the SEN-500-2 and SEN-500-3 Outdoor Air
Temperature Sensors Product/Technical Bulletin (LIT-216179).
In the event of a power failure, or 10 minutes after an N2 communication loss, the thermostat
retains the last setpoints. When power is restored, it remains in normal operation and does
not require resetting. If power was lost when the thermostat was in Night mode, it returns to
Day mode.
There are three binary input points to cause a COS that triggers the remote NDM to dial out.
Binary Inputs 1 and 3 (wrench and filter) are general purpose inputs powered by 24 VAC or
22-30 VDC. Binary Input 2 is the Temperature Alarm binary data point that causes a COS if
the zone temperature is moving away from the setpoint after 45 minutes. The COSs operate
regardless of which stages are on. Overrides remain after the NDM hangs up.

Verifying Proper Thermostat Operation
Selecting an Operation Mode
To verify proper thermostat operation:
1. Press the Mode button to select the Heating or Cooling mode.
2. Press the ∨ or ∧ buttons to raise the setpoint above or below the
current ambient temperature. The thermostat calls for either heating or
cooling.
To energize each stage of heating quickly, set the heating setpoint 2°F
above the present room temperature. Wait for the Heat icon displayed on
the Liquid Crystal Display (LCD). For example, if the room temperature is
70°F, set the heating setpoint to 72°F. The first stage of heating should
energize. Once the Heat icon is off, readjust the setpoint 2°F above the last
setpoint (for example, 74°F). When the Heat icon is off, adjust the setpoint
2°F higher (76°F), to energize the auxiliary heat (TEC1102 model only).
Press the Mode button to select from the modes listed in Table 13.

Selecting a Temperature Scale
Press the ∨ and ∧ buttons simultaneously to alternate between Celsius and
Fahrenheit display. This does not affect the BAS display. For example,
hotel room temperature can be displayed in °F on the Companion system,
but a hotel guest can switch the local display to °C. If power loss occurs,
the TEC reverts to the last network command (in this example, °F).
Selecting Fan Operation
Displaying Outdoor/Duct Air Temperature
Setting the Electronic Outdoor High and Low Balance Points
For continuous operation, press the Fan button and the Fan icon ( )
appears. If the Fan button has not been selected, the fan operates
automatically on a call for heat or cool (no fan symbol appears).
When an outdoor or duct temperature sensor (order separately) is
connected to the TEC1100 thermostat or if the outdoor air temperature is
available from the N2 network, press the Outdoor button. The
temperature is displayed along with corresponding icons ( ). The
Metasys BAS can display the Outdoor Duct Air temperature when mapped
back. The TEC1102 uses the outdoor air sensor or N2 value for low
temperature compressor lockout and high temperature heating lockout.
When there is no N2 command and the sensor option is not connected, the
thermostat displays --- when the button is pushed.
To use outdoor air lockout, you must set the high and low balance points.
Any outdoor temperature above the high balance point locks out the
auxiliary heat, and any outdoor temperature below the high balance point
allows the auxiliary heat to run when called for by the thermostat.
Similarly, any outdoor temperature below the low balance point locks out
the compressor, and any temperature above the low balance point allows
the compressor to run when called for by the thermostat. Both balance
points can be set from -48 to 50°C (-55 to 125°F).
Note: To set the high and low balance points, an outdoor sensor must be
attached to the unit.
To set the high and low balance points for outdoor air lockout:
1. Press and hold the Outdoor button, then press the Mode button. HibP
appears in the display, meaning high balance point, along with the
current balance setpoint.
2. Press the ∨ and ∧ buttons to set the high balance point temperature.
3. Press the Outdoor button. LobP appears in the display, meaning low
balance point, along with the current balance setpoint.
4. Press the ∨ and ∧ buttons to set the low balance point temperature.
5. Press the Mode button to resume operation.
