INTERFACING THE TRANSMITTER WITH THE STEFFES 1000
and 2000 SERIES ROOM HEATING UNITS:
All heater locations referenced below are accessed through
the faceplate on the front of the 1000/2000 Series heater.
Refer to the Owner's Manual for operating instructions.
____ 1. Verify that the heater is operating on the same channel as the
transmitter by checking the setting in Location 11 (L11) of the
heater. The heater is factory preset to operate on channel 1.
____ 2. O nce good communication is established between the transmitter
and the heater, the lower right indicator light on the heater’s
faceplate illuminates green continuously.
____ 3. If utilizing the transmitter’s automatic charge control features,
compare the information in Location 46 (L46) of the heater’s
control circuit board to the actual outdoor temperature. This
location will display a hex value approximating the current
outdoor temperature. If the temperature information in L46 is
reading substantially higher or lower than actual outdoor
temperature, refer to Dip Switch Settings 7 and 8.
If the transmitter is installed indoors and automatic charge
control is desired, a remote outdoor sensor is required.
INTERFACING THE TRANSMITTER WITH THE STEFFES 2100
SERIES AND COMFORT PLUS SYSTEMS:
The "Help Menu" on the heater is a ccessed through the
faceplate on the front of the heater. Refer to the Owner's
and Installer's Manual for operating instructions.
Using the "Help Menu" on the heater’s control panel:
____ 1. Verify that the heater is operating on the same channel as the
transmitter. The 2100 Series heater is factory preset to operate
on channel 1. Comfort Plus systems are not factory preset for
power line carrier.
____ 2. Verify that power line carrier communication is occurring.
____ 3. If utilizing the transmitter’s automatic charge control features,
compare the outdoor temperature information from the "Help
Menu" to current outdoor temperature. If the temperature
information in the help menu is substantially higher or lower
than actual outdoor temperature, refer to Dip Switch Settings 7
and 8.
GENERAL OPERATION
The Steffes Power Line Carrier (PLC) Transmitter is a device used for
communicating information through the local electric circuits to an
unlimited number of Steffes microprocessor based heating systems
(1000, 2000, 2100, 3100, 4100, and 5100 Series) and other controllable
devices incorporating the Steffes PLC receiver. A receiver is built into
Steffes microprocessor based heating systems, so the transmitter can
communicate directly with the equipment without the cost of additional
controls or electrical wiring. Therefore, overall installation costs of an
ETS system can be significantly reduced, especially in multiple unit
installations and projects such as hotels, motels, apartments, condos, etc.
The transmitter must be wired into the line voltage power serving the
installation. The transmitter continuously sends information through the
local electric circuits. This information is received by the Steffes heating
equipment and other controllable devices with a correlating receiver,
provided they are on the same power company distribution transformer as
the transmitter.
INSTALLATION
Mount the transmitter in the desired location.
If utilizing the built-in outdoor temperature sensing
thermistor, it is important to place the transmitter in an area
where it will NOT be exposed to direct sunlight.
Line Voltage Connections
This device can be connected to 120V or 208V/240V, single phase.
In most applications, optimum performance is achieved
when connected to 208V/240V.
The PLC transmitter is factory
configured for 208V/240V field
connections. DO NOT connect the
transmitter to 277V unless the
identification label indicates it is
suitable for 277V. A three-phase
option is available as a special order.
WARNING
HAZARDOUS VOLTAGE: Risk
of electric shock, injury, or
death. All line voltage wiring
connections MUST be made
within and routed through the
line voltage raceway of the
transmitter’s factory installed
junction box.
