Features
- Limit value monitoring for CO2 concentration and humidity
- Dewpoint alert e.g. for cooling ceilings and winter gardens to
prevent possible mould growth.
- Two binary inputs for connecting zero-voltage contacts.
- Logic gates for easy linking functions.
Sensor
- Up to four different limits can be set for the CO2-sensor.
- Adaptation to current sea level above NN.
- Up to two limits can be set for the humidity sensor.
Controller
- 5 operating modes: Komfort, standby, night, frost or heat
protection, and controller lock-out (e.g. dew-point mode).
- Heating/cooling functions: Heating, cooling, heating and cooling,
basic and additional heating, basic and additional cooling.
- Preset control parameters for common radiators or cooling units.
- Controller deactivatable (dewpoint operation) or controller or
operation of the controller can be blocked.
- Valve protection function (valve is opened cyclically every 24
hours).
- Control types: continuous PI control, switching PI control (PWM),
and switching 2-point control (on/off).
Inputs
- Free assignment of the functions switching, dimming, blind and
value transmitter to the inputs.
- Blocker for blocking individual inputs.
- Behaviour can be configured following bus voltage recovery.
- Telegram rate limit.
- Switching function: two independent switching objects are
available for each existing input and can be enabled individually,
command for leading and trailing edge can be set independently
(ON, OFF, CHANGE, no reaction).
- Dimming function: single-surface and double-surface operation,
time between dimming and switching, and dim-step size can be
set, telegram repetition and stop telegram transmission possible.
- Blind function: command can be set with rising edge (no
function, UP, DOWN, SW), operating concept can be
parameterised, time between short and long-term operation
adjustable, slat adjustment time adjustable.
- Value transmitter and light scene auxiliary unit function: edge
(button as NO contact, button as NC contact, switch) and value
with edge can be configured, value adjustment by pressing and
holding a button for value transmitters possible, light scene
auxiliary unit with/without memory function.
