when monitored rooms are vacant!

HVAC Smart Relay Switch

  • Description
    Rising fuel costs have highlighted the need for efficient energy use in hotels, universities, rental properties, and other facilities. The HVAC Occupancy Switch (HOS) is a low-cost temperature control solution for heating and air conditioning systems in situations where energy management is desired. The HOS continually monitors one or more rooms for occupancy. When they are determined vacant for a preset period of time, the HOS takes control of the system and shuts it off. A predetermined delay periodically re-activates the system to maintain an adequate comfort level. The controller accepts input from 4 wired sensors and 8 wireless sensors. (Note: 100 ft. max. cable length for each wired sensor input. Twisted-pair shielded cabling recommended.) The HOS works with the existing hvac system and there is no need to replace existing equipment or thermostats. Pre-programmed vacancy and re-activation periods can be adjusted on-site using convenient onboard setup switches.
