Neptronic thermostat controllers offer the use of the “Out of Service” writable property. When set to true, this
property disconnects the object from the physical input, enabling you to input other values. This could be useful
for special applications or when troubleshooting. For example, you can ignore the temperature read from a
sensor and input the desired temperature value in order to perform specific tests.
For security reasons there is a timeout that will set the Out of Service property back to false after 15 minutes.
This value can be modified to between 0 and 120 minutes (see proprietary property #1002).
