Solar pump operation time after starting panel defrosting
mode.
Default setting: 120s
Activating the detection of gravity heat convection from the
tank.
Default setting: NO.
Serpentine collector function.
By analysing panel temperature changes the controller
periodically activates the solar pump for the time set in this
parameter. It can measure the instantaneous temperature of
the panel and activate tank heating or panel overheating
protection function.
Default setting: 0s = function disabled.
Function protecting the solar panel from freezing. This
parameter determines the panel temperature below which the
solar pump is activated in order to protect the solar thermal
fluid from freezing or thickening. If tank temperature drops
below 4°C, the controller will switch off the anti-freeze
function. Selecting 10.0°C disables the function.
Default setting: 10°C = function disabled
ANTI-LEGIONELLA function involves periodic sterilization of
the tank. This parameter determines the set tank temperature
when this function is enabled. Sterilization starts weekly on
Monday at 11:00 a.m. It stops when the temperature reaches
the value set in this parameter.
