- If configured as Normally closed: notification if connection status is
open. If the status switches to closed, the notification disappears.
There is no direct application operation based on the universal contact
status change.
– Outside air temperature
– Room air humidity
– Presence detector
– Condensation monitor. If the thermostat receives an input from a
condensation monitor, it will display a notification on the mobile app. The
thermostat does not alter operation based on this input.
– Room air quality
● Change input signal types based on the assigned input type. The following
signal types are supported:
NOTICE! If the corresponding application hasn't been configured, some
inputs may not be selectable.
– Digital input, normally open or closed
– 1k Ohm @ 32 F Ni RTD (LG-Ni1000)
– 1k Ohm Pt. RTD (385a)
– 1k Ohm Pt RTD (375a)
– Type 2 Thermistor
– 0 to 10 V*
● Set sensor evaluation mode if an external sensor is connected to either
terminal X1 or X2. You can use either the built-in and external sensors, or the
external sensors, for controlling and monitoring. The former is selected by
default. However, if no physical external sensors are connected to any control
inputs or if the input values are invalid, only the built-in sensors are used
instead to provide values for the thermostat. If external sensors are connected
and can provide valid values with the built-in sensors, the thermostat reacts
differently depending on the type of the external sensor:
– Displays the average value if it is an external temperature or humidity
sensor.
– Takes the higher value if it is an external VOC sensor.
– Enable presence detection related functions no matter whether it is the
external or the built-in presence detection sensor detects that someone is
in the room.
● If the selected equipment type is Heat pump, decide if the heat pump shall be
switched off below a certain outside air temperature. If yes, specify the default
temperature value. Note that an external outside air temperature sensor is
required to be connected with the thermostat to get the outside temperature.
● If the selected equipment type is Heat pump and auxiliary heating is allowed to
operate when the heat pump is running, you can decide if the auxiliary heating
device shall be switched off above a certain outside air temperature. If yes,
specify the default temperature value. Note that an external outside air
temperature sensor is required to be connected with the thermostat to get the
outside temperature.
● Configure the output as a humidifier, humidifier free-standing, dehumidifier,
dehumidifier free-standing or an outside air damper.
● Activate or deactivate dehumidification. If the output is not configured as a
dehumidifier or dehumidifier free-standing, the thermostat takes use of the heat
pump or cooling system to dehumidify the space. However, the heat pump
turns off cooling (if cooling operation is running) whenever there is a
dehumidification command.
● Activate or deactivate ventilation. Only when the output is configured as an
outside air damper can the ventilation function be activated. The ventilation
function is mainly used to improve the room air quality when the room is
detected to have worse air quality than the configured room air quality setpoint
under the Optimization page.
