Th e following set points are used for temperature control
Par3111: DHW Comfort set point (typically used in the daytime, when time bands have been set)
Par3112: DHW Economy set point (typically used at night, when time bands have been set)
Par3114: DHW Over boost set point (this value allows the DHW tank to be heated to a temperature above the
set point, either Comfort or Economy)
The DHW can be heated as following configuration by setting Par3102.
Par3102=0: Fill DHW tank with HP unit + heater in replacement mode (in this case the HP unit will be used
while this is able to heat the DHW tank, then operation will continue using the immersed heater).
Par3102=1: Fill DHW tank with HP unit only
Par3102=2: Fill DHW tank with DHW Electric heater only
