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. In transmit mode, it receives a signal from an external control

device such as a power company’s meter or radio receiver, a time clock, or other control device. The transmitter interprets the signal and sends the signal to any Steffes receivers installed on the same distribution transformer. The transmitter also collects and transmits outdoor temperature data. Steffes heating systems have a built-in receiver. There are also relays in the transceiver which can be used to control other loads.

In receive mode, the transceiver reads and translates the signal from the transmitter. It uses the information received to control other electric load devices by turning power off and on to the device with its relays. Other controlled-load devices might be an electric water heater, electric baseboard heater, electric clothes dryer, etc.

NOTE: PLC Communication is very reliable in most applications but can be affected and hindered

by connection method used, electrical layout of the application, operation of other equipment in the same electric system, dirty power, etc. Steffes Corporation does not guarantee effective communication of the PLC system in all applications and is not responsible for communication issues.

TRANSMIT MODE DIP SWITCH SETTING S

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. If unsure whether or not the signaling device opens or closes for charging, contact the power company.

ON = Close to Charge (Off-peak), Open for Control (Peak)

OFF = Open for Charge (Off-peak), Close for Control (Peak)

DIP Switches #2, 3, 4, 5 – Channel Selection

DIP switches 2, 3, 4, and 5 are used to select the channel on which the transceiver will transmit (send signal). There are 15 channels available. Only one transceiver is required per distribution transformer. If multiple transceivers in the transmit mode are installed on a single distribution transformer, they must be set to different channels. Select a channel and set DIP switches 2-5 according to the chart below:

Option**

* Steffes 1000 and 2000 Series room heating units receive only on “slow” speed channels (Channels 1 or 2 as set

from the factory or on channe ls 12/13 or 14/15 with a software upgrade). Slow chan nel s transm it a signal every 34 minutes, so can take up to 7-10 minutes for a receiver to receive. Fast channels transmit every minute, so it generally only takes 2-3 minutes to receive.

** The Steffes transceiver transmits a signal over the power lines constantly unless set to one of the intermittent

transmit channels shown above. If the power company’s control device is power line carrier (PLC) such as those manufactured by Cooper Power System/Cannon Technologies, the transceiver must transmit intermittently to allow the power company’s control device to operate properly. When set to tra nsmit inter m i ttently, the Steffes Heating systems will display a lower -than-normal percentage of good packets received.

Page 18

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.

The second function of DIP switch #6 is to allow for an automatic shoulder charge period for devices controlled by the relays on the transceiver. When in the “on” position, the transceiver has a built in timer that starts timing when it receives a peak signal from the power company’s control device. It times for 5 hours and then allows a shoulder charge period (anticipated peak) for 4 hours. After four hours of shoulder charge, the peak period is resumed until a charge signal is received from the control device. More information regarding this feature is available in the Relay Operation section of this manual.

DIP Switch #7 – Negative Outdoor Temperature Calibration

DIP switch #7 is used to adjust the outdoor temperature reading being transmitted to the Steffes receivers by 5° F (2.78° C) lower than the actual outdoor temperature. This DIP switch is only used if the heating system is reading an outdoor temperature higher than the actual outdoor temperature.

DIP Switch #8 – Positive Outdoor Temperature Calibration

DIP switch #8 is used to adjust the outdoor temperature reading being transmitted to the Steffes receivers by 5° F (2.78° C) higher than the actual outdoor temperature. This DIP switch is only used if the heating system is reading an outdoor temperature lower than the actual outdoor temperature.

RECEIVE MODE DIP SWITCH SETTINGS

DIP Switch #1 – Anticipated Peak (Pre-Peak) Operation Mode

This DIP switch determines how an anticipated peak (pre-peak) signal will affect the relays. For power companies desiring to control loads separately using separate signals, this DIP switch can be used to do peak control of devices on a separate rate strategy. Generally, anticipated-peak signals are not used and this DIP switch should be placed in the "OFF" position.

ON = Relays will be activated by an anticipated peak (pre-peak) signal.

OFF = Relays will NOT respond to an anticipated peak (pre-peak) signal.

DIP Switches #2, 3, 4, 5 – Channel Selection

DIP switches 2, 3, 4, and 5 are used to select the channel on which the receiver will receive. The receiver and the transmitting device MUST be set to the same channel for proper communication to occur. To select the desired channel, use the chart on page 14 and set DIP switches 2, 3, 4, and 5 accordingly.

DIP Switch #6 – Automatic Shoulder Charge (Specialty Applications Only)

DIP switch #6 is to allow for an automatic shoulder charge period for devices controlled by the relays on the transceiver. When in the “on” position, the transceiver has a built in timer that starts timing when it receives a peak signal from the power company’s control device. It times for 5 hours and then allows a shoulder charge period (anticipated peak) for 4 hours. After four hours of shoulder charge, the peak period is resumed until an off-peak or anticipated peak signal is received from the control device.

To enable the shoulder charge timers, turn DIP switch #6 to the ON position.

ON = Shoulder Charge Enabled

OFF = Shoulder Charge Disabled

DIP Switch #7 – Default Relay Status

DIP switch #7 determines how the relays will respond when the power line carrier control system is first energized or if the receiver loses signal from the transmitting device.

ON = The relays will close until a signal is received from the transmitting device.

OFF = The relays will open until a signal is received from the transmitting device.

LED FUNCTIONS

reception when using a “fast” channel and

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.

LED 3

When s et up as a transmitter, LED 3, (3), blink s OFF and ON in 4 second intervals with a percentage of ON time as based on the outdoor temperature. The graph below illustrates the percent of time the LED is ON at various temperatures.

The warmer the outside temperature, the longer the LED stays ON. At 65° F or warmer, the LED is ON solid.

When the operation mode is receiver, LED 3 indicates when the PLC signal reception is established from the transmitting device. It blinks OFF-and-ON slowly then increasingly faster until it is ON solid. ON solid indicates that PLC reception is “locked in”.

NOTE: It can take 2-3 minutes for PLC signal

7-10 minutes when using a “slow” channel.

LED 4

LED 4, (4), responds to the power company’s control signal.

• OFF when receiving an off-peak signal

• ON solid if an override switch is enabled

• blinking OFF and ON according to the type of

signal being received from the control device.

This graph illustrates the time, in seconds, the LED is OFF-and-ON during various types of signal periods.

NOTE: Power company peak signal overrides

anticipated-peak and/or setback signals.

Page 21

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. The push-button override switch, (1), and the three zone override module, (2).

PUSH-BUTTON OVERRIDE SWITCH

1. When using the push-button override switch,

connect the two purple override wires to the OVR and OVS terminals on the transceiver board’s low voltage terminal block.

2. Connect a jumper wire from OVC to OV1 to

override relay #1 and/or from OVC to OV2 to override relay #2.

NOTE: Refer to the Relay Operation section for

more information on which relays will utilize the various override inputs.

3-ZONE OVERRIDE MODULE

1. Mount the module into a 2-gang box anywhere in the structure where it will be convenient for the user

to access.

2. If using the 3-zone override module, remove applicable transceiver knocko u t(s) from the bottom of the

enclosure below the low-voltage connection area.

3. Connect wires to low-voltage terminal circuit connection points to match circuit leads marked on

override module circuit board (OVS to OVS, OVR to OVR, etc.). Tighten terminal screws securely.

4. The module contains five (5) low

voltage wires: 3 purple, 1 yellow, 1 red, and 1 orange/black. Splice 18/6 low voltage wire to these wires and route them through the low voltage raceway compartment in the transceiver.

5. Using only line voltage rated wire inside

the transceiver, connect the override to the low voltage terminal strip in the transceiver as follows:  Purple wires connect to OV1, OV2,

OV3, or OV4 terminals

 Red wire connects to OVR terminal  Orange/black wire connects to OVS terminal  Yellow wire connects to OVC terminal

6. Label each override zone on the module and in the relay panel (inside, on the front cover label).

7. Install the front cover on the transceiver and energize the system.

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. The light on the

3-Zone Override Module corresponds to LED4 in the Transceiver.

3. To deactivate the override of a zone, press the zone(s) rocker switch(es) to the “Disable” position. The override period can be cancelled by pressing the Override Start/Stop rocker switch again.

Testing the 3-Zone Override Module

1. Initiate a peak mode. Check voltage between T1 and L2 positions of the main wiring terminal block on those circuits connected to the override. There should be no voltage present on any of the circuits.

2. Activate the override by pressing the Start/Stop rocker switch once. Press the rocker switch for Zone 1 to the “Enable” position.

3. Test voltage between T1 and L2 positions of the main wiring terminal block on those circuits connected to Zone 1 Override. There should be a voltage reading. Press Zone 1 rocker switch to the “Disable” position.

4. Follow steps 1-3 to test voltages of those circuits connected to Zone 2 and Zone 3 of the override as well.

CHECK OUT PROCEDURES

CHECK OUT PROCEDURE FOR TRANSMI T MODE

1. Turn power on to the transceiver.

2. Look at LED-L3, (1). It should blink OFF-and-ON at a rate

based on the outdoor temperature.

3. Look at LED-L4, (2). It may be:

• OFF when receiving an off-peak signal

• ON solid if an override switch is enabled

• blinking OFF and ON according to the type of signal being

received from the control device.

4. Simulate an off-peak period.

• If DIP switch #1 is in the ON position, this can be done by placing a jumper wire across the R and P terminals.

• If DIP switch #1 is in the OFF position, an open across R and P will simulate the off-peak period.

5. LED-L4 should be OFF and the relay LED’s should all be ON.

6. 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.

7. Simulate a peak period.

• If DIP switch #1 is in the OFF position, this can be done by placing a jumper wire across the R and P terminals.

• If DI P switch #1 is in the ON position, an open across R and P will simulate the peak period.

• Look at the relay LED’s. They should all be OFF.

8. Look at LED-L4. It should be blinking at the peak rate as shown for Peak (P) Signal.

Page 23

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 RECEIV E MODE

1. Turn power on to the transceiver.

2. Look at LED-L3. It should blink OFF-and-ON slowly then increasingly faster until it locks ON indicating it has received PLC signal from the transmitter.

NOTE: It can take 2-3 minutes for PLC signal reception when using a “fast” channel and 7-10

minutes when using a “slow” channel.

3. Look at LED-L4, (2). It may be:

• OFF when receiving an off-peak signal

• ON solid if an override switch is enabled

• blinking OFF and ON according to the type of signal being

received from the control device.

4. Simulate an off-peak period at the transmitting device.

• If DIP switch #1 is in the ON position at the transmitting device, this can be done by placing a jumper wire across the R and P terminals.

• If DIP switch #1 is in the OFF position at the transmitting device, an open across R and P will simulate the off-peak period.

5. LED 4 should be OFF.

6. The relay LED’s should all be ON.

7. Go to each controlled load (appliance) and make sure it is operating.

8. Simulate a peak period at the transmitting device.

• If DIP switch #1 is in the OFF position at the transmitting device, this can be done by placing a jumper wire across the R and P terminals.

• If DIP switch #1 is in the ON position at the transmitting device, an open across R and P will simulate the peak period.

9. Look at the relay LED’s. They should all be off.

10. Look at LED-L4. It should be blinking at the peak rate as shown.

11. If one of the optional overrides has been installed, verify proper operation of the override device.

When checkout is complete, make sure:

• DIP switches are all set to the

proper position

• jumper wire has been removed

from the transmitting device

• all wiring connections are

tight
