11.2 Digital inputs
The following volt-free contacts can be connected to digital inputs D1 and D2:
• Presence detector or window contact (for details of this function see Section 5).
• Safety thermostat electric heating coil / reheater (for details of this function, see
page 96).
• Safety thermostat outdoor temperature (for details of this function, see page 109).

Do not connect the same type of sensor/functions to more than one digital input.
The controller would ignore the second input.

The figures above illustrate the air circulation alarm function of the room controller:
• An alarm is only possible 30 s after the controller has given a fan command (fan start
phase).
• A closed alarm contact is ignored for 30 s (debouncing), only then an alarm message
is issued.
• An electric heater is disabled during the fan start phase (30 s).
• When an alarm message is issued, the electric heater is disabled immediately;
the fan will continue to run during the fan overrun time defined by P098.
