belonging to the same thermostat group signals an open contact (open window, for example).
In this mode any setpoint values sent from the control unit in automatic operation are ignored.
• antifreeze (written
Min
, icon ) : used to set a minimum temperature level to avoid damage
to pipework or prevent the temperature from falling below a safety level.
• nighttime reduction (written
rED
, icon
): the temperature is set according to the set-point
for nighttime reduction.
• timed nighttime reduction (written
rED
, icon
): the temperature is set according to the
set-point.
• automatic (written
Aut
, icon ) : the temperature will be adjusted automatically according
to the setpoint received from the control unit.
• manual (written
MAn
): used to set switching the system on and off manually.
• timed manual (written
