Nest Learning Thermostat IV  
TPI room thermostat, for use with on/off output heaters: An electronic room +2%  
thermostat that controls both thermostat cycle rate and in-cycle on/off ratio  
of the heater proportional to room temperature. TPI control strategy reduces  
mean water temperature, improves room temperature control accuracy and  
enhances system efficiency.

Nest Learning Thermostat VI  
Weather compensator and room sensor, for use with modulating heaters:  
A heater flow temperature control that varies the flow temperature of water  
leaving the heater dependant upon prevailing outside temperature and  
selected weather compensation curve. A room temperature sensor monitors  
room temperature and adjusts the compensation curve parallel displacement  
to improve room comfort. Control is achieved by modulating the output  
of the heater.
