The brick core charging of the 1000 series room heating unit is capable of being controlled by low voltage
wiring, by a time clock or WIRELESS with the use of the Steffes Power Line Carrier (PLC) control system.
If using the wireless method, only one PLC system is needed in an installation; and, it can be mounted indoor
or outdoor. It will transmit the load management control switch signal through the entire power line system in
the home or building. In addition to controlling the heater, it will transmit outdoor temperature information
for automatic brick core charging. An installation procedure manual will accompany the PLC control system.
Depending on which method of heating element control is being used, the unit configuration dip switches will
need to be set accordingly. (See Figure 13 for location of these dip switches in the heater.) The function of
each dip switch is as follows:
Dip Switch #1 = Invert Peak Signal (Should be "ON" if using a time clock for control purposes.)
Dip Switch #2 = Not used (Should always remain in "OFF" position.)
Dip Switch #3 = Invert Occupied/Not Occupied Signal (Room Temperature Set Back)
Dip Switch #4 = Invert Anticipated (Pre-Peak) Signal
Dip Switch #5 = Enable Auxiliary Heat Call Feature
Dip Switch #6= Automatic Charge Control Configuration (Should be "ON" if a direct wired outdoor sensor is
being used for automatic brick core charge regulation.)
Dip Switch #7 = Security (Editing Control) Mode
Dip Switch #8 = Used for factory purposes ONLY. (Must always remain in "OFF" position.)
If the dip switch button is set in the up position, the dip switch is in the "ON" (activated) position.
If the dip switch button is set in the down position, the dip switch is in the "OFF" (deactivated)
position. See Figure 13 for location of the dip switches in the heater.

Note 1: On 120V systems, the L2 terminal block position MUST always be the ungrounded "HOT"
conductor.
