Winter/summer operation
There are different options for changing
between winter and summer operation.
2-pipe installations
Manual changing between sun (winter) and
snowflake (summer) operation on the panel.
Jumper position (1-2)
External changing via 230 V AC -signal on
input IN2 from a dominant system or heat
pump (CHANGEOVER). In the event of a
signal the fan convector changes to summer
operation. Jumper position (2-3).
4-pipe installations
Automatic changing between winter and
summer operation according to diagram
"Function diagram with neutral zone". Valves
are required for heating and cooling (on/off)
and a hot water circuit and cold water circuit
must be available.
• Jumper position (1-2)
• DIP-1=OFF
• DIP-2=OFF
When the fan convector is set to summer
operation and is switched off, i.e. switch
on the control panel is at 0 (OFF), a timer
activates the fan for operation for 2 minutes
every 15 minutes.
