Providing temperature control for electrical baseboard heaters or other electrical based heating systems


The baseboard controller uses wireless technology to monitor a room’s state eliminating sensor wiring normally required for temperature control applications. Wireless energy harvesting sensors monitor temperature, room occupancy and window or patio door state to provide feedback to the controller on the appropriate operating mode.

This translates into more consistent and comfortable temperature control for occupants with energy saving and allows a quick retrofit project for building operators.

The controller operates with electric baseboard heaters, controlling when the baseboard is active to maintain a consistent temperature in the room based on the temperature set point.

  • Supports baseboard voltages of 120 or 208VAC 
  • Near-Cross switching technology for long relay life
  • UL508 and CSA 22.2 No.14 listed 
  • Remote management and reporting for BEMS integration 
  • Monitors battery free keycard switches, occupancy sensors, and window switches 
  • Low-cost alternative to running wires around windows and through walls. 
  • Central command support for centralized control 
  • Supports commissioning via Simple Tap™ and Garibaldi software

Room temperature is provided by a wireless wall mount temperature sensor with an optional set point knob. Adjustment of the room temperature set point is much easier on a wall sensor eliminating an occupant having to crouch down to access a knob on the heater. For larger rooms, adding additional temperature sensors for averaging temperature control is easy.  


Room occupancy state also has an effect on controller operation. A wireless occupancy sensor provides updates on the room occupancy so the heater is not outputting the same heat when vacant. A proximity switch can also indicate when a window or patio door has been left open so the heater is not trying to heat the outdoors.  


Baseboard heaters in hospitality applications can use keycard switches which allows an occupant to use the front door keycard to indicate when they’re in the suite. All the switches and sensors implement energy harvesting and do not require any wires. This permits a quick installation so adding automated temperature control becomes much easier.
