These can then be fed directly into an output device, if this\n * is continuously variable, or they may be passed to node-red-contrib-timeprop nodes to generate\n * time proportioned on/off outputs.\n * There are two particular issues to be dealt with in a heat/cool application. Firstly is the fact\n * that the cooling device may be more or less powerful than the heating device. It is necessary\n * therefore to be able to adjust the gain of the system separately for heating and cooling. Secondly\n * is the highly non-linear response of some devices, notably refrigerant systems, that can have a\n * large effect initially, then this tails off. To compensate for this it is useful to have an \n * overlap range where both heat and cool are slightly on.\n *\n * To allow for these requirements two variables can be set below. The value of the power input value\n * where the heating starts to come on is determined by the variable heatMin.  Above this value the\n * heating will rise till it is fully on with an input of 1.\n * The cooling is fully on when value of the power input is 0, and falls till the cooling is fully\n * off at an input of coolMin.\n *\n * If the heating and cooling systems are of similar power then set heatMin and coolMin both to 0.5\n * in which case input values of 0.5 to 1.0 will map to heating outputs of 0.0 to 1.0,\n * and 0.5 down to 0.0 will map to cooling 0.0 to 1.0.\n * If, for example, the cooling system is more powerful than heating then they can both be set\n * to something like 0.7 which increases the gain in the heating region and reduces it\n * in the cooling region, to compensate for the different powers in the heating/cooling systems.\n * If some overlap is desired (so that both
