i have a customer with one particular room in his building that isnt used very often. because of this he doesnt want to heat/cool the room daily. there is no set schedule day/time when the room is used so a programmable thermostat isnt the best solution. he does not want to depend on his employees to turn the RTU off when finished in the room, so a non-programmable thermostat isnt the solution either.
im looking for a system with motion detection that when motion is sensed will bring the room to preset occupied temperature settings. if the motion detector doesnt detect additional motion within a preset time frame, the system should default to preset unoccupied temperature settings until motion is again detected.
many of the larger hotels have similar systems in their guest rooms, but my experience is limited to the "Energy IQ" systems that i installed somewhere around 1998 and i havent seen or heard anything of them since. in fact, i dont know if they still even produce the same products.
