How do I recommission the Passiv Smart Thermostat?

Firstly, go to the Passiv Programmer and hold down the up and down buttons together to enter the installer menu. Navigate to and select the option to 'Rerun commissioning'. Once you have confirmed that you wish to recommission the system you'll be able to go through the commissioning process again and adjust any previous mistakes. 

Note: You can check what was set during the commissioning process at any time by selecting 'System Summary' from the installer menu.
