The voltage-free digital input provides the following configuration options:
• Close for ECO (default)
• Open for ECO
• Close for OFF
• Open for OFF
• Changeover: Toggles stage 1 control between heating and cooling.
• Disable cooling: Disables the cooling stages if ON (condensation protection)
• Contact alarm
• Bus
• Close for BOOST
• Open for BOOST
Close for ECO ⁄ OFF
Link the voltage-free digital contact to an external timer, for example,
to switch the controller into OFF mode while the timer is counting down.
When the system switches from open (comfort mode) to closed (ECO-/OFF mode),
the operating mode only changes after the timer has counted down.
Open for ECO ⁄ OFF
Use the voltage-free digital input to enable ECO or OFF mode when the contact opens. In this operating mode,
it can be used to connect a window switch, door card switch or PIR sensor. When the system switches from
closed to open, the operating mode changes only after the timer configured in the parameter "Digital Input
Delay" has counted down.
Changeover
You can use the digital input for priority switching from heating to cooling mode (see chapter "Changeover").
The controller works in heating mode if the contact is open, and in cooling mode if the contact is closed.
Disable cooling (condensation protection)
When the digital input closes, the cooling control circuits are set to 0 % to prevent condensation.
In this mode, the digital input is normally connected to a condensation sensor.
NOTE: Configuring the digital input against condensation has priority over the operating mode of the resistance
input against condensation (RI1 and RI2).
Contact alarm
When the digital input closes, the display shows a "DI contact alarm" message.
Bus
The digital input is used for monitoring purposes via the bus.
No further effects on the unit control.
Close/open for BOOST
The digital input switches the controller into boost mode until it re-disables boost mode.
When boost is enabled via the digital input, the display shows "Boost" instead of the target temperature.
NOTE: The parameter "Digital Input Delay" applies to all the configurations mentioned.
