figuration is needed .

The relays for pump and boiler are potential free contacts and can thus NOT be used as direct power
supply . Max . load is 230 V, 8 (2) A .

respective output .

The Away Function ensures a set room temperature fixed at 15°C for all Room Thermostats,
but it can be changed with the Danfoss Link™ CC .

nals for Away Function . When this switch is closed
(ON) the system will override all room thermostat
set points and change it to 15°C .
