Connecting the LONWORKS Network
The wiring rules for the LONWORKS network differ from
the wiring rules for the Metasys® N2 Bus and the
BACnet® MS/TP Bus. For more details on wiring the
LONWORKS network, refer to the LONWORKS Network
Layout Technical Bulletin (LIT-1162150).
Toconnect the thermostat to the LONWORKS network:
1. Connect the LONWORKS network wires to the
LONWORKS network terminal block on the
thermostat (Figure 5, Figure 6, Figure 7, and
Figure 8).
Note: There is no polarity when connecting the
LONWORKS network wires to the thermostat; however,
we recommend keeping the polarity consistent
throughout the network.
2. After the LONWORKS network wires are connected
to the first thermostat, continue in a daisy-chained
fashion to the next device.
Note: The LONWORKS network wiring must be twisted-
pair lines.
Do not run the LONWORKS network wiring in the same
conduit as line voltage wiring (30 VAC or above) or
other wiring that switches power to highly inductive
loads (such as contactors, coils, motors, or
generators).
The LONWORKS network requires proper termination
and biasing at the end of a segment (a segment is a
physically continuous length of wire). The thermostat is
not equipped with the ability to provide this termination;
therefore, it cannot be located at the physical end of a
LONWORKS network segment unless a terminator is
attached. Refer to LONWORKS Network Layout
Technical Bulletin (LIT-1162150) for end-of-line
solutions.

Comf/eco Selects how the auxiliary heat is
used.
Default: comfort
(economy) – in the heating mode: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized to satisfy
the setpoint only when the temperature has dropped 2F°/1C° below
the heating setpoint.
Note: Selecting economy in the heating mode adds a deadband
between the heat pump and auxiliary heat. The actual
temperature maintained is lower than the true heating
setpoint to maximize the heat pump operation. When the
outdoor air temperature drops below the low balance point,
the deadband is eliminated.
(economy) – in the emergency heat mode: The setpoint that is
maintained is the heating setpoint.
(comfort) – in the heating mode: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized to satisfy
the setpoint.
Re valve Governs the reversing valve
operation.
Default: O
(B): Energizes the valve in heating operation (valve is normally cool)
(O): Energizes the valve in cooling operation (valve is normally heat)
Comp/aux Sets the mode of interaction
between the heat pump and the
auxiliary heat.
Default: off
(on) – in the heating mode only: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized and the
heat pump is shut off. This typically applies when the air handler
heat pump coil is installed after the auxiliary heat. There is a
2-minute delay to restart the heat pump after the auxiliary heat is
shut down.
(off) – in the heating mode only: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized at the
same time as the heat pump stage. This typically applies when the
air handler heat pump coil is installed before the auxiliary heat (all
electric systems).
