4. Connect the FLN.
5. Connect the point wiring (see Wiring Diagram s).
6. Plug the room temperature sensor cable into the
RTS port.
7. Connect the power trunk. DO NOT apply power
to the controller without first consulting the
specialist. This TEC is designed to work with 2-
wire AC power (Neutral and Phase (hot) at 24
Vac +/-20%. Using the earth terminal is optional
and, if used, it should be connected to the
nearest earth ground (building steel, conduit or
duct work (if earthed)).)
CAUTION
It is very important that the neutral
that supplies the TEC must be earth
grounded at the source of the 24 Vac
power.
Possible erratic equipment operation
or damage if neutral is not grounded.
The installation is complete.

NOTE:
The controller’s DOs control 24
Vac loads only. The maximum
rating is 12 VA for each DO. An
external interposing relay is
required for any of the following:
• VA requirements higher than
the maximum
• 110 or 220 Vac requirements
• DC power requirements
• Separate transformers used to
power the load
(for example, part number 540-
147, Terminal Equipment
Controller Relay Module)
