DIP Switch #1 - Invert Peak
In low voltage installations, the transceiver will look for an open or closed signal across the R and P terminals on the low voltage terminal block. The transceiver must be set to match the signaling device.
ON = Close to Charge (Off-peak), Open for Control (Peak)
OFF = Open for Charge (Off-peak), Close for Control (Peak), Steffes Connect for control.
DIP Switches #2, #3, #4, #5 - PLC Channel Selection
DIP switches #2, #3, #4, and #5 are used to select the PLC channel the transceiver will transmit on (send signal). There are 15 channels available. Only one transceiver is required per distribution transformer. If multiple transceivers in 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:

*Steffes 1000 and 2000 series room heating systems receive only on slow speed channels. Slow channels can take 7-10 minutes for a receiver to receive. Fast channels usually take 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. If the power company’s control device is power line carrier (PLC), such as those manufactured by Cooper Power Systems and Cannon Technologies, the transceiver must transmit intermittently to allow the power company’s control device to operate properly. When set to transmit intermittently, the Steffes heating system will display a lower-than-normal percentage of good packets received.
DIP Switch #6 - Service Override & Nova Scotia Shoulder Charge
DIP switch #6 has two functions: 1) a short-term peak override for checkout and service of the system, and 2) enabling a shoulder charge period (Nova Scotia Power only). To enable a 3-hour peak override, power up the transceiver, move DIP switch #6 from OFF to ON, and back to OFF.
Nova Scotia Power installs only: DIP switch #6 allows the shoulder charge period for devices controlled by relays 1, 3, and 5 on the transceiver. When in the ON position, the transceiver has a built-in timer that starts when it receives a peak signal from the power company’s control device. It times for five (5) hours and then allows a shoulder charge period (anticipated peak) for four (4) hours. After four (4) hours of shoulder charge, the peak period resumes until a charge signal is received from the control device.
DIP Switch #7 - Negative Outdoor Temperature Calibration
Use DIP switch #7 to adjust the outdoor temperature reading being transmitted to the Steffes receivers by 5°F (2.78°C) lower than the actual outdoor temperature.
DIP Switch #8 - Positive Outdoor Temperature Calibration/Access Point (AP) Mode Enabled/Disable
Use DIP switch #8 to adjust the outdoor temperature reading being transmitted to the Steffes receivers by 5°F (2.78°C) higher than the actual outdoor temperature.
You can also use DIP switch #8 to force the transceiver into or out of Access Point (AP) mode. When in AP mode, the network used by the device for Internet access can be modified. To change the AP mode status, toggle DIP switch #8 two (2) times in short succession (ON-OFF or OFF-ON).
