Frequently Asked Questions

How accurate is my temperature sensor?
It is accurate to +/- 0.5°C.
Can I place an offset on the sensor to compensate for the heat?
You can set a temperature offset for the internal sensor on the Sensors/Overview page. You will need to be logged in as an admin user and select the Wrench Icon next to the Device Label.
What are the most popular remote sensors?
Remote Temperature for monitoring "hot" spots and other trouble areas. Water Sensor to check for water leaks. Door Contact Sensor to see if a door is open. Remote temperature / air flow / humidity for ensuring the proper environment. Climate monitoring in remote locations.
What is the difference between analog and digital sensors?
Analog sensors connect through the analog inputs. These sensors are either a dry contact or provide a 0 to 5VDC signal. On the Web interface, they show up as "IO" sensors and have a value 0 to 99. Digital sensors connect to digital input ports and communicate through a serial protocol. These are also referred to as Plug-n-Play, Remote, or External sensors. Digital sensors are auto-detected by the climate monitor. Measurements from these devices are graphed and report in the appropriate units.
