Important information
For safety reasons the heating system must have a bypass
function. This is either built into the boiler or it must be
installed in the system.
Demount other heating control timers in the installation or
they will interfere with the Danfoss Link heating control
algorithm. If weather compensation is present it should be set
to constant comfort.
