The boiler pump can function in two ways.
0 Intermittent - The pump is controlled according to the heating
request of a room thermostat or remote control
1 Continuous - In 'Winter' mode the pump runs continuously
If the reading of the external sensor is not correct it is possible to
adjust the reading to correlate with the true outside value
