Method and apparatus for controlling a temperature regulation system

A temperature regulation system for use in controlling the temperature within the cabin of a vehicle, the temperature regulation system comprising:

• at least one temperature regulator;
• a first temperature sensor for measuring a first temperature, T1;
• a second temperature sensor for measuring a second temperature, T2;
• and
• a controller configured to receive measurements of T1 and T2 from the first and second temperature sensors,
• the temperature sensors being located within the cabin such that the first temperature sensor is located at a higher level than the second temperature sensor when the vehicle is on a level surface,
• the controller being configured to:
• receive an input indicative of time passed since start up;
• calculate a representative temperature, TR, wherein TR is calculated using T1 and T2;
• and operate the temperature regulator according to the calculated value TR for a predefined period of time after start up, and thereafter operate the temperature regulation system according to the measured value of T2.
