SHK 200S / SHK 200S-6 i METROAIR L
The conductor connecting the devices must be con-
nected to the power supply clamp (TB) at METROAIR
L and to clamp (X0) at SHK 200S / SHK 200S-6 .
Connect the phase (brown), neutral conductor (blue),
communication (black and grey) i protective (yellow-

Emergency Mode Thermostat
When the controller automation is in the emergency
mode (SF1 is set as ), only the most necessary
functions are active.
• Domestic hot water is not heated.
• Constant temperature in the supply pipeline;
more information to be found in the Chapter
Emergency Mode Thermostat.
In the emergency mode, the supply temperature is set
using a thermostat (BT30). It must be set according to
the demand of the circuits in operation. The available
regulation range is between 6 and 67°C. Remember
that for floor heating, the settings must be min. 20°C,
max. 35-45°C in order to preserve heat comfort in the
room and assure effective system operation.
