Our new web-based application pairs with compatible Steffes Transceivers to provide homeowners visibility and control* of their Steffes heating systems from anywhere at any time. Steffes Connect delivers Internet of Things (IoT) functionality to compatible transceivers, which can be installed with a new or existing Steffes heating system. It can also control electric devices, such as a dishwasher, freezer, washing machine, water heater, or other electric heating devices in the home.


  • Control Steffes heating system from anywhere, any time using a web-connected device
  • Check current rate status (peak, off-peak, shoulder)
  • View rate schedule (dependant upon Power Company)
  • Adjust room units to the home or away setting*
  • Check indoor temperature and/or outdoor site temperature**
  • Control other electric devices on the same rate schedule
  • Schedule automatic home/away heater setting changes
  • Receive optional notifications for online and offline status and/or temperature limits

*Specific room temperature cannot be manipulated.
**May require the purchase of an Indoor and/or Outdoor Temperature Sensor Kit.

Remote Room Temperature Sensor

This sensor provides remote room temperature information to room units or it can be used to provide freeze protection temperature signals to furnaces.

  • Disables the room unit’s built-in temperature sensing system to allow monitoring of room temperature at another location in the room.
  • Available in configurations that control 1, 2, or 3 heaters simultaneously
  • Direct wired to the heater using low voltage, 2-conductor cable
  • 2 ¾” X 4 ½” off-white enclosure
Outdoor Temperature Sensor

This accessory provides outdoor temperature information for automatically regulating brick core temperature.

  • Comes standard with all furnaces, optional add-on control with room units
  • Can be wired directly to the heater or to a Steffes Power Line Carrier (PLC) load management control system
  • If direct wired to the heater, one sensor is needed for each heater
  • If direct wired to a PLC control system, only one sensor is needed for the entire application
  • 40′ low voltage, 2-conductor cable
  • Mounting bracket provided or can be mounted into a knockout using its ½” male pipe thread nipple


The Steffes Transceiver is a control device used to manage Steffes heating systems and other electric loads. The Transceivers use a communication protocol called Power Line Carrier (PLC) which operates at very low radio frequencies to transmit information over electric power transmission lines. Information is transmitted via PLC from the Transceiver to all listening devices (heaters), allowing them to take advantage of electric utilities’ low-cost off-peak rate  programs.

Transceiver Features


  • Use for control of many electrical devices: Steffes heating systems, water heaters, electric baseboards, electric furnaces, ceiling and floor heat, and other electric devices
  • 2-pole or 5-pole configurations (each pole providing a single 30 AMP DC held, board mounted relays)
  • 15 selectable channels for PLC communication 
  • 1-hour peak override option (with single button or zonal control accessory module)
  • Metal enclosure with power company seal/lockout provision
  • Optional factory pre-wired umbilical cord in rain tight conduit configuration
  • 120V or 208V/240V, 1 phase or 3 phase configurations
