Bed microclimate control based on sampling

A method for controlling a microclimate of a mattress, comprising:

• activating a heating element to heat air;
• activating a reversible fan in a direction to supply the heated air to a top of the mattress;
• controlling the reversible fan in an opposite direction to draw an amount of air from the top of the mattress for a predetermined period time;
• detecting a temperature of the amount of air drawn from the top of the mattress;
• and
• activating the heating element and the reversible fan again whereby activation of at least one of the heating element and the reversible fan is adjusted based on the temperature detected
• wherein activating the reversible fan in the direction comprises supplying the heated air to the top of the mattress over a first period to control a microclimate at the top of the mattress,
• wherein controlling the reversible fan in the opposite direction comprises sampling air temperature at the microclimate over a sampling period by reversing airflow to draw air from the mattress to a temperature sensor, and
• wherein activating the heating element and the reversible fan again comprises supplying air to the mattress again over a second period whereby air is supplied in a manner different than during the first period as a function of the air temperature sampled while airflow was reversed.

A method for controlling a microclimate of a mattress, comprising:

• activating an air conditioning element to condition air;
• activating a reversible fan in a direction to supply the conditioned air to a top of the mattress;
• controlling the reversible fan in an opposite direction to draw an amount of air from the top of the mattress for a predetermined period time;
• detecting a temperature of the amount of air drawn from the top of the mattress;
• and
• activating the air conditioning element and the reversible fan again whereby activation of at least one of the air conditioning element and the reversible fan is adjusted based on the temperature detected,
• wherein activating the reversible fan comprises:
• activating the reversible fan in the direction to supply the conditioned air to a top of the mattress for a first period of time to control a microclimate at the top of the mattress,
• wherein controlling the reversible fan in an opposite direction comprises:
• controlling the reversible fan in the opposite direction to draw an amount of air from the top of the mattress for a second period time, the second period of time being shorter than the first period of time, and
• wherein activating the air conditioning element and the reversible fan again comprises:
• activating the air conditioning element and the reversible fan again for a third period of time whereby air is supplied in a manner different than during the first period of time as a function of the detected temperature of the air drawn during the second period of time.
