SETTING THE METHOD OF BRICK CORE CHARGE CONTROL
With automatic charge control, outdoor temperature information can be supplied to the room heating unit in
one of two ways: Steffes power line carrier system or direct wired outdoor sensor.
The room heating unit is shipped from the factory set for automatic charge control for use with the Steffes
power line carrier control system. The heater comes preset to start charging at an outdoor temperature of 60
o F
(15.6 o C) and to be at a full core charge level at 20 o F (-6.7 o C). (The installing electrical contractor or power
company personnel will have more information on how to adjust these temperatures to more accurately reflect
the climate in your area, if necessary.)
Power Line Carrier and Automatic Charge Control
The Steffes power line carrier (PLC) control system has the capability of sending outdoor temperature infor-
mation, WIRELESS, to an unlimited number of 1000 series heater for automatic charge control. No direct
wiring to the heater is required with a PLC control system. The outdoor temperature information is transmit-
ted through the existing power line in the home or building. The heater's built-in receiver will pick up the
signals being transmitted through the power lines and respond accordingly. PLC control is available with the
use of the Steffes PLC Transmitter or the Steffes Comfort Control Relay Panel (CCRP). Only one PLC
system is needed in an installation. If using the PLC Transmitter and installing it outdoors, an outdoor sensor
may be utilized but is not required. If installing the PLC Transmitter indoors or if using the CCRP's built-in
PLC system, one external outdoor temperature sensor is required for automatic charge control. An installation
procedure manual will accompany the PLC Transmitter and CCRP. Please refer to these instructions for
installation of either device.
If using a PLC signal for transmitting outdoor temperature information, Dip Switch #6 inside
the heater on its control board must be in the "OFF" position. (Refer to the Typical Control
Wiring Diagrams section in this manual for more information on the heater's dip switches.)
Direct Wired Outdoor Sensor and Automatic Charge Control
An outdoor sensor can be direct wired into each room heating unit using low voltage wire. One outdoor sensor
is required for each room heating unit that is installed. An installation instruction sheet is included with the
outdoor sensor. Please refer to these instructions for installation of this device. (Order item #1302026.)
With a direct wired outdoor sensor, Dip Switch #6 inside the heater on its control board must be
in the "ON" position. (Refer to the Typical Control Wiring Diagrams section in this manual for
more information on the heater's dip switches.)
Manual Charge Control
No additional devices are required for brick core charging if the charge level is to be set manually by the user.
Since the heater comes factory preset for automatic charge control, Location 19 (L19) must be adjusted to
manual control. Location 7 (L07) should also be adjusted so that both room and brick core temperature can be
adjusted after the M button is pressed for a few seconds. (The installing electrical contractor or power
company personnel will have more information on how to make these adjustments.)
REMOTE ROOM SENSOR
All 1000 series room heating units come factory equipped with a built-in room temperature sensor. This
sensor is installed in the electrical compartment on the right side panel of the heater, near the floor. In installa-
tions where it is desired to monitor temperature at another point in the room, a remote room temperature sensor
may be used. If a remote sensor is installed, the built-in sensor is disconnected. The remote sensor will
provide the room temperature information to the heater and is available from the factory in three different
configurations whereby one, two, or three heaters can be connected to one sensor. The number of heaters to be
controlled by one sensor must be specified at the time of order of the sensor. Current room temperature is
dislayed on the heater's face plate whether the built-in sensor or remote sensor is being used. An installation
instruction sheet is included with the remote room sensor. Please refer to these instructions for installation of
this device. (Order item #1302024.)
