A local thermostat for controlling an HVAC unit may include a controller programmed to execute a remote access function for remotely accessing and communicating with at least one remote thermostat over a communication channel. The remote access application may be configured to display at least one thermostat setting of at least one of the remote thermostats on the display of the user interface of the local thermostat. In some cases, the remote access application may allow a user to change one or more thermostat settings of at least one remote thermostat using the user interface of the local thermostat.

Thermostat with remote access feature

Methods and apparatus for automatically changing between heating and cooling in an HVAC system. In one example, an HVAC controller may monitor the temperature of an inside space of a building, and may switch the HVAC system to cooling when the temperature of the inside space rises above a high switch-point temperature, and may cool the inside space to at least below the high switch-point temperature. The HVAC controller may also switch the HVAC system to heating when the temperature of the inside space falls below a low switch-point temperature and may heat the inside space to at least above the low switch-point temperature. In some cases, after switching to heating or cooling, the HVAC controller may cause the HVAC system to heat or cool the inside space, respectively, to substantially the set-point temperature.
