Page 5: General Operation
SYSTEM USE DURING CONSTRUCTION PHASE Like most heating equipment manufacturers, Steffes strongly recommends that “Construction Heating Units” be used instead of the permanent heating system during the construction phase. Use of the permanent heating system during this phase may contaminate the duct system and/or internal areas of the heating system. -
Page 6: Control Panel
AM and PM Indicator Lights The AM and PM indicator lights are only utilized if the Steffes Time Clock Module is being installed. With this module installed, the system displays time on AM/PM intervals and the corresponding light flashes. The system can be configured to CONTROL PANEL display military time, in which case both the AM and PM lights illuminate. -
Page 7: Temperature Control
TEMPERATURE CONTROL Temperature set point is adjusted at the wall thermostat(s) or the main system control. If temperature in the area drops below the desired set point, a heat call is initiated and the blower in the ThermElect system is energized. The variable speed core blower automatically adjusts speed in relation to brick core temperature and duct tem- perature to circulate air through the brick core. -
Page 8: Optional Accessories
Optional Accessories LOAD MANAGEMENT CONTROL The ThermElect is a commercial Electric Thermal Storage (ETS) heating system. It uses Demand Free, Off-Peak electricity to provide a low cost heating solution for commercial, industrial, and large residential applications. ETS equipment is designed to store electricity, as heat, during hours when energy costs are lower and kW demand charges are not incurred. -
Page 9: External Duct Sensor
EXTERNAL DUCT SENSOR The optional external duct sensor (Order Item #1041536) provides the ability to monitor the duct temperature at an area beyond fresh air makeup and/or beyond other devices and regulate the discharge air temperature accordingly. The duct sensor feature is enabled if the 4 bit is set in Location 53 (L053). -

When interfacing with an air condi- special installation require- tioner, the indoor coil can be placed on either the supply air or return air ments that MUST be performed. -
Page 20: Line Voltage Electrical Connections
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. All 208/240V systems are factory configured for automatic charge control with a direct wired outdoor sensor. -
Page 21: Thermostat Connections
A low voltage room thermostat is required for room temperature control with the system. Any room thermostat used with this system must be 24 VAC. (Contact the factory for more information on the thermostats available from Steffes.) INSTALLING THE THERMOSTAT Step 1 Disconnect power to the system and route low voltage wire between the thermostat and the system. -

Step 10 Verify, once again, that the Operating Mode displayed on the control panel corresponds with the power company's peak control signal. Step 11 In applications utilizing the Steffes Power Line Carrier control system, complete the Installer’s Final Check-Out Procedure in the Owner’s and Installer’s Manual provided with that device. -
Page 24: Load Management Control
The ThermElect system may be controlled by the Power Company via a peak control signal. This signal can be sent to the equipment using low voltage wiring, a Steffes Time Clock Module, or a Steffes Power Line Carrier control system (208 and 240V applications only). In applications utilizing automatic charge control, outdoor temperature information is required and can be received via an outdoor sensor or power line carrier control system. -
