– 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.
