Locking the IC902 Thermostat
The thermostat can be locked to prevent tampering of the thermostats parameters. There are two types of locks.

tank sensor offset calibration „CA1‟). System status parameters can still be viewed and level 1 parameters can
be accessed and changed.

each time level 1 parameter access is required.
Note: Both locks may be activated to prevent tampering with all parameters. In this case only system status
parameters can be viewed.
