GENERAL OPERATION

The Steffes Power Line Carrier (PLC) Mini Receiver is designed to provide wireless control of one electrical circuit (single pole configuration), two electrical circuits (double pole configuration), or six electrical circuits (six pole configuration). It receives signals through the existing power lines from the Steffes Power Line Carrier (PLC) Transmitter or Comfort Control Relay Panel (CCRP). The built-in 30 AMP relay(s) are capable of controlling devices such as: ETS heaters, water heaters, baseboards, electric furnaces, dryers, dishwashers, hot tubs, ceiling cables, or other electrical equipment. When the mini receiver receives a signal, its relay(s) are activated to control the device(s) connected to them. This type of control can minimize the overall cost of controlling electrical devices.

FEATURES

INDICATOR LIGHTS

In its standard configuration, when the mini receiver is first energized, a red light on the circuit board will begin to flash slowly. This indicates the receiver is waiting for a signal. When valid bits of information are received, the light will begin flashing more rapidly. There may be occurrences where the light will switch from a fast flash back to a slow flash. After several minutes, the mini receiver will synchronize with the transmitter, and the light will illuminate continuously to indicate complete information is being received. This red light monitors power line carrier (PLC) communication as follows:

TYPICAL SYSTEM WIRING DIAGRAM

(six pole configuration)

Slow Flash: Mini receiver is waiting for PLC communication. Fast Flash: Mini receiver is receiving partial PLC communication. Continuous Illumination: Mini receiver is receiving complete PLC

information

There is also an amber indicator light on the circuit board. This light is used to indicate whether the relays are open or closed. It will also indicate if a peak override has been initiated. The amber light monitors the status of the relays as follows:

No Illumination: relay(s) open Flashing: overrride enabled Continuous Illumination: relay(s) closed

These lights can only be seen when the mini receiver enclosure is open. They are not accessible to the user in normal operation.

OVERRIDE OPTION (Power Company Permitting)

The mini receiver is available with a 90-minute override option. If the override is incorporated, it allows the use of a normally controlled device(s), such as a water heater, during a peak control time. It allows for a single override of either all connected circuits or a one zone override of circuits 1, 3, 5, and 6. This feature works well in areas using a Time-of-Use rate/control strategy. (Installation instructions for this feature are provided with the override module, item #1302070.)

(This end is connected at the Factory

An override period can be initiated during a “peak” period or if communication between the transmitter and mini receiver is lost. To do so, press and hold the override button for 2 seconds. A new 90-minute override period can be initiated any time during a current override cycle. When an override is initiated, it cannot be cancelled manually. The override will cancel itself at the end of the 90-minute override cycle or at the start of the next off-peak period, whichever comes first.

The position of dip switch #8 on the mini receiver circuit board will determine which relays are enabled when an override is initiated. (For more information, refer to the Dip Switch Settings section in this manual.)

DIP SWITCH 6: AUTOMATIC SHOULDER CHARGE

(Specialty Applications Only)

This dip switch allows for a shoulder charge period for the device controlled on relay #1. Five (5) hours after a peak signal is received, relay #1 will close for four (4) hours if the outdoor temperature is below 35 degrees Fahrenheit. The relay will then open again and will remain open until an off-peak or anticipated peak signal is received. If an off-peak or anticipated peak signal is received during the five hour period, the timer will reset.

FACTORY DEFAULT SETTING = OFF

Off = Shoulder charging disabled On = Shoulder charging enabled

The duration of the delay and the outdoor temperature settings are preset at the factory. If you have an application which requires a change to these settings, please contact the factory.

DIP SWTICH 7: DEFAULT RELAY STATUS

This dip switch determines how the relay(s) will respond when the power line carrier control system is first energized or if the mini receiver loses signal from the transmitter.

FACTORY DEFAULT SETTING = OFF

Off = The relay(s) will open until a signal is received from the PLC

transmitter.

On = The relay(s) will close until a signal is received from the PLC

transmitter.

DIP SWITCH 8: PEAK CONTROL OVERRIDE

With the addition of the override module to the mini receiver, peak override of some or all of the circuits is possible. Depending upon the position of this dip switch, either all circuits in the mini receivers or just those connected to relays 1, 3, 5, and 6 can be used in 90-minute intervals during a peak control period, if desired.

FACTORY DEFAULT SETTING = ON

Off = Circuits connected to relays 1, 3, 5, and 6 are enabled during a peak

control time when an override cycle is initiated.

On = All circuits in the mini receiver are enabled during a peak control

time when an override cycle is initiated.

DIP SWITCH 9: RELAY 3 AND 4 FUNCTION SELECTOR

This dip switch is used in conjunction with dip switch 6. If dip switch 6 is in the on position, the position of dip switch 9 will determine how relays 3 and 4 will respond.

FACTORY DEFAULT SETTING = OFF

Off = Relays 3 and 4 will function like relay 2 On = Relays 3 and 4 will function like relay 1

DIP SWITCH 10: RELAY 5 AND 6 FUNCTION SELECTOR

(Six Pole Configurations Only)

This dip switch is used in conjunction with dip switch 6. If dip switch 6 is in the on position, the position of dip switch 10 will determine how relays 5 and 6 will respond.

FACTORY DEFAULT SETTING = OFF

Off = Relays 5 and 6 will function like relay 2

On = Relays 5 and 6 will function like relay 1

INSTALLER’S FINAL CHECK OUT PROCEDURE

_____ 1. Prior to energizing the electrical circuit feeding the mini receiver,

inspect all field installed electrical connections to ensure they are tight and that all wires are routed correctly. All line voltage wiring must remain below and in front of the line voltage barrier inside the mini receiver. To ensure proper communication with the PLC transmitter, the mini receiver must be grounded.

____2. Check the settings of the dip switches on the mini receiver board to

ensure they are in the correct positions for the application.

The desired PLC channel MUST be selected for communication to occur.

_____ 3. Check to ensure that the red indicator light on the mini receiver circuit

board is illuminated continuously indicating communication is occurring between the transmitter and the mini receiver.

Communications between the transmitter and the mini receiver occur on a continuous basis. Upon energizing a

system, there will be some delay in a receiver’s response to transmitter signals. It takes approximately seven (7) minutes for the transmitter to establish initial communication. Subsequent communication will occur more rapidly.

____ 4. Once good communication is established, verify that the mini receiver

responds correctly to the corresponding utility peak signal status. The amber indicator light will illuminate when the relay(s) are closed and should remain off when the relay(s) are open.
