The thermostat can use wireless (X10 wireless protocol) or wired occupancy sensors. Bay
sells a low cost wireless occupancy sensor that is ready to use with the BAYweb Thermostat.
Just put in a couple of batteries and mount it in a location that typically sees activity when you
are home. You can use as many sensors as needed enabling the thermostat to monitor
multiple locations in your home for occupancy.
Wired occupancy sensors can use either normally open or closed contacts. Motion sensors
from most alarm systems are compatible with the BAYweb thermostat.
Occupancy sensing with pets in the home is accomplished by masking off the lower part of
the sensing lens.
You should locate your sensors in high-traffic areas of your house so that they will be most
likely to sense when people are present. The sensors from Bay have a 10+ foot range and will
sense people as they pass in front of the sensor. We have found that locating them at about
chest height or higher works well.
Once you have installed your occupancy sensors login to the web portal to enable them. To
enable occupancy sensing select the “Schedule” page from the thermostat applet menu and
set the “Occupancy Inactivity Time”. We suggest using 1 hour for this interval initially, you can
adjust this value later if needed to suit your lifestyle.
If you are using sensors not supplied by Bay, you may need to configure the thermostat to
look for other wireless IDs or to monitor the wired input. This is done on the “Settings” page of
the thermostat applet.
After enabling occupancy sensing review your schedule and set your “Sensing”, “Sleep” , and
“Home” times as described above. Your thermostat will now automatically adapt your HVAC
operation to match your lifestyle.
Testing Occupancy Sensing
If you want to see if the sensors are working as expected, login to the web portal and select
“Sensor Log” from the thermostat applet menu.
The thermostat applet “Operation Log” will give a detailed view of occupancy sensing
operation.
Occupancy Sensing with Multiple Thermostats
If you are using multiple BAYweb thermostats in the same building, and wish to have each
thermostat sense occupancy (using wireless sensors) in separate areas, you will need to
configure the occupancy sensors with different X10 device IDs.
The default X10 ID of Bay supplied sensors is “A1”. Note that these sensors also use ID “A2”
for internal purposes, do not use ID “A2” for occupancy sensing. Refer to the instructions
provided with the sensor for detail on how to change the sensor's X10 ID. Configure the
thermostat to look for the alternate X10 IDs on the “Settings” page of the thermostat applet.
