time clocK moDule PeAK control
The Steffes time clock module (Order Item #1301014) is another option
for providing a peak control signal to the heaters. The optional time clock
module is installed inside the heater’s line voltage electrical compartment
and interfaces with the heater’s relay board. Peak control times are required
to be programmed into the heater once the module is installed to enable the
time clock feature.
In addition to providing peak control signals, the time clock module can
also provide automatic room temperature set back, if desired. Refer to the
instructions provided with the time clock module for more information on
the installation and operation of this device.
line VoltAge PeAK control
Line voltage peak control is also an option, but is not the preferred method as it is usually more complex and
expensive. If line voltage control is utilized, the blower/control circuit of the heater must be powered with
an uninterrupted circuit. An external switching device, such as a relay panel, is necessary to directly control
the heating element charging circuits. If relying on this method of control, the faceplate on the heater must
continuously display a brick core operating mode of “C” (charge) regardless of whether it is an off-peak or on-peak
time.

The outdoor temperature sensor can be installed in one of two
ways: direct wired to the system or wired to the Steffes power
line carrier system. If direct wired to the heater, one sensor
per heater is required. Refer to the Low Voltage Connection
Diagrams (Figures 7 and 8) and the instructions included with
Unless servicing, power
to the heater should not
be turned off at the circuit
breaker when using the
Steffes Time Clock Module.
If power is off to the blower/
control circuit for an
extended period of time, it
may be necessary to reset
the current day and time.

2100 Series Installation 2.08
Installation Methods: A) Hard wired to the heater
Or
B) Connected to Power Line Carrier (PLC) - reference Owner's and Installer's Manual for
this installation.
Theory of Operation: The outdoor sensor monitors outdoor temperature and provides this information to the
system. The system responds by automatically storing heat in its brick core according to
outdoor temperature and the heating requirements.
location of: The outdoor sensor must be placed in a location where it can accurately sense outdoor temperature
and is not affected by direct sunlight or other abnormal temperature conditions.
Wiring to heater: • Route low voltage wire from the outdoor sensor to the electrical compartment through one
of the low voltage wire knockouts.
• Connect to the two gray wires in the low voltage raceway.
• If the sensor wiring is routed through an external wall, the opening through which the wire
is routed MUST be sealed. Failure to do so may affect the accuracy of the outdoor tem-
perature sensor.
• The outdoor sensor can be extended up to a total of 250 ft if needed.
• Unshielded Class II (thermostat) wire can be used as extension wire as long as it is segre-
gated from any line voltage cabling.
• No other loads can be controlled or supplied through this cable. It is for connection of the
outdoor sensor ONLY.
• This low voltage cable MUST not enter any line voltage enclosure.
If connecting to the Steffes power line
carrier (PLC) system, follow the instal-
lation instructions in the PLC system's
Owner's and Installer's Guide.
