value
Defines the max. heat output percentage of the boiler during
DHW phase compared to the max. heat output available
Defines the min. output percentage of the boiler in CH mode
Defines the max. output percentage of the boiler in CH mode

0 - Intermittent - In winter 'mode' the pump is controlled by the
room thermostat or remote control
1 - Continuous - In winter 'mode' the pump is always
energised, therefore always running
