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.
