Disclosed are exemplary embodiments of apparatus and methods for remote testing of controllers such as thermostats, to detect incorrect climate control system configuration parameters. In an exemplary embodiment, a mobile device wirelessly connects with a remote thermostat and sends signal(s) to the thermostat instructing the thermostat to perform climate control function(s) in predefined sequence(s). The mobile device receives signal(s) from the thermostat indicating whether the thermostat is performing the climate control function(s) in accordance with the sent signal(s). Based on the signal(s) received from the thermostat, the mobile device determines whether the thermostat is configured with accurate climate control system configuration parameters.
