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 .
