7.3.8 Difference thermostat function
This function allows a controller output to be controlled depending on
a pre-defined temperature difference.
When the temperature difference exceeds the defined "on" value, the
output is switched on until the temperature difference falls below the
"off" value. For optimised functionality, unloading of the heat source can
be limited to a particular temperature range, and loading of the heat
target can be limited to a maximum value.
It is also possible to limit the difference thermostat function to specific
times.
