When the new minimum HPV valve set point has been reached or the current set point is greater than this
minimum value, the action to increase the gas cooler set point is started. It should be noted that this is not
linked to the percentage of heat recovery demand, but rather is applied once a minimum demand threshold
is exceeded.
