Smart Remote

The Smart Remote function is used for remote access to the controller via a
4-state signal.
DIn1 and DIn2 of the controller are digital switching inputs. The switching states are
On (contact closed) and Off (contact open).
Mode DIn1
SR off On
Normal operation Off
SR Plus Off
SR on On
The Smart Remote function is automatically deactivated when the power control
is carried out via the sensor module variant.
In the SR off operating status, the electric heating is switched off regardless of the
excess measured. The internal backup heating and the booster are blocked.
During normal operation, the automatic control is carried out depending on the
excess measured and with optional internal backup heating.
In the SR Plus operating status, the electric heating is operated at nominal power
regardless of the timer and the excess measured. Operation is stopped when the
switch-off temperature of the internal backup heating is reached at the allocated
sensor. Without internal backup heating, operation is stopped when the store max-
imum temperature is reached at S1.
In the SR on operating status, the electric heating is operated at nominal power
regardless of the timer and the excess measured until the store maximum temper-
ature is reached at S1.
