GENERAL OPERATION General Information This Steffes Power Line Carrier (PLC) Transceiver is to be installed in your customer's home or business to provide communication to and control of Steffes heating systems and/or other devices. The PLC Transceiver is used for communicating information through the local electric circuits and must be wired into the line voltage power serving the installation. The transceiver can be installed as a transmitter OR a receiver.

COMPONENT LOCATION 2-POLE INDOOR/OUTDOOR Use this illustration to familiarize yourself with the location of parts you will use as the transceiver is installed, set up, and its operation checked. The 2-pole transceiver shown is an outdoor enclosure; however, all components are located in relatively the same locations in the indoor enclosure.
COMPONENT LOCATION 5-POLE INDOOR Use this illustration to familiarize yourself with the location of parts you will use as the transceiver is installed, set up, and its operation checked.
COMPONENT LOCATION 5-POLE OUTDOOR Use this illustration to familiarize yourself with the location of parts you will use as the transceiver is installed, set up, and its operation checked.
COMPONENT LOCATION 3-PHASE Use this illustration to familiarize yourself with the location of parts you will use as the transceiver is installed, set up, and its operation checked.
UNIT IDENTIFICATION LABEL The unit identification label shown is a sample.
TRANSCEIVER INSTALLATION CAUTION: Risk of eye injury due to flying debris. Wear eye protection at all times during this installation. IMPORTANT: Maximum Transceivers per Utility or Distribution Transformer – The transceiver can be installed as a transmitter OR a receiver. Install no more than four transmitters on one distribution transformer. There is no limit to the number of receivers in a system. Remove Enclosure Cover Rainproof Enclosure 1 1. Remove two screws, (1). 1 2.
Line Voltage Connections 2-Pole WARNING: Hazardous Voltage. Can cause injury or death. 1 2 Route line-voltage conductors (circuit board power and controlled-load circuits) and make linevoltage connections only in the line-voltage connection area, (1). Use only copper conductors that are rated for 75° C minimum. Route low-voltage conductors (remote outdoor sensor, power company signal/control switch, override switch, etc.) only into the low-voltage connection area, (2).
Line Voltage Connections 5-POLE WARNING: Hazardous Voltage. Can cause injury or death. Route line-voltage conductors (circuit board power and controlled-load circuits) and make line-voltage connections only in the line-voltage connection area. Use only copper conductors that are rated for 75° C minimum. Route low-voltage conductors (remote outdoor sensor, power company signal/control switch, override switch, etc.) only into the low-voltage connection area.
Transceiver Relay Connections 2-Pole (Optional) CAUTION: Risk of fire. Can cause personal injury or death. Use only copper conductors that are rated at 75° C.` minimum. 1. If any transceiver relay(s) are NOT being used to control other loads, insulate the ends of the unused wires. 2. If the transceiver relay(s) are being used to control other loads, one leg of the circuit going to the controlled load will be broken through the relay. 3. To use controlled-load Relay #1, use the red relay wires, (1).
Transmit/Receive Select Jumper 1. The transceiver can be used as a transmitter OR JUMPER POSITION AFFECTS OPERATION a receiver, dependent upon how the TR/RC jumper is positioned. 2. To use as a transmitter, place the select jumper is on the “TR” position as shown (jumper covers the left and center pins). 3. To use as a receiver, place the select jumper to the “RC” position (jumper covers the center and right pins).
DIP SWITCH SETTINGS Factory Defaults DIP Switch # 1 2 3 4 5 6 7 8 Setting ON ON ON OFF OFF OFF OFF OFF TRANSMIT MODE DIP SWITCH SETTINGS DIP Switch #1 – Invert Peak The transceiver receives a signal, (i.e. switch closure), related to on-peak or off-peak from the power company or other signaling device. The signal may be a switch “open-to-charge” or “close-to-charge” signal. The transceiver must be set to match the signaling device.
DIP Switch #6 – Service Override & Automatic Shoulder Charge DIP switch #6 has two functions. The first function is to provide a short term peak override for checkout and service of the system. If the transceiver is powered up and DIP switch #6 is moved from the “off” position to the “on” position and back to “off” again, a 3 hour override will be enabled. This short term override is to be used when installing or servicing the system.

LED FUNCTIONS LED 1 and 2 The relays on the transceiver have LED’s. On the 2pole transceiver, these are marked Relay 1, (1), and Relay 2, (2). When the corresponding LED is on, the relay is energized and should be closed. When the corresponding LED is off, the relay is not energized and should be open. 1 2 LED 3 When set up as a transmitter, LED 3, (3), blinks OFF and ON in 4 second intervals with a percentage of ON time as based on the outdoor temperature.
ELECTRONIC OVERRIDE MODULES (OPTIONAL) The Steffes Override Modules are optional devices that allow the use of a normally controlled device, such as a water heater, during a peak control time (power company permitting). Either override timer will allow for an override of the relays. The override duration is 90 minutes (1.5 hours). It can be cancelled anytime during the cycle. There are two electronic override controls available to use with the transceiver.
Operating the 3-Zone Override Module 1. The module is marked with three separate zones: Zone 1, Zone 2 and Zone 3. These zones correspond to the relays in the transceiver. To enable the override module, press the Override Start/Stop rocker switch once. The green indicator “Override On” light will illuminate. 2. To activate the override of a zone, press the zone(s) rocker switch(es) to the “Enable” position. NOTE: Zone 1, 2 or all three can be enabled at the same time in any sequence.
9. Make sure PLC signal is received by each controlled device: transceiver receiver, Steffes Heating Systems Electric Thermal Storage (ETS) heater, receivers, and all other controlled loads to ensure that these loads turn off. When checkout is complete, make sure: • DIP switches are all set to the proper position • jumper wire has been removed • low voltage connections have been reconnected • all wiring connections are tight CHECK OUT PROCEDURE FOR RECEIVE MODE 1. Turn power on to the transceiver. 2.
