Button
The main function of the button is to switch on the pump. Pressing the button will
turn the pump on, releasing the button will switch it off. It can be actuated anytime
regardless of the controller’s function mode. It is used to test the pump. The other
function is the alarm reset, which turns the alarm sound off.
Jumper
During winter time, if the temperature drops below the given value, the collector
turns the pump on to avoid water/antifreeze to get frozen in the system. The
function of the jumper is to set whether the system is filled with antifreeze liquid or
not.
In case the controller is set to antifreeze mode, during winter time when the
temperature of the collector reaches -20 °C, it will start the pump and will run it
until the temperature of the collector reaches -15 °C. When the antifreeze mode is
off, the pump will start at -5 °C and will switch off at 0 °C to avoid the freezing of the
water in the system.
Holiday switch
By switching the vacation mode on with the holiday switch at the bottom of the
controller, it can be ensured that the system keeps the temperature of the tank on
a certain level where the water cannot be overheated while not in use. This
happens during the night, by the pump automatically switching on when the
temperature in the water tank is higher then 40 °C and the temperature in the
collector is lower then 40 °C. The pump is running until the temperature of the
water tank cools down to 40 °C.
