KNX object Control btn I/F 4-gang System 55 cream white

Description

The control function is used for single-room temperature control. The controller detects the current room temperature with an internal or external temperature sensor and computes an adjustment size using it and an adjustable setpoint temperature. Valve drives can be controlled with a constant adjustment signal or with a switching adjustment signal here.

The object regulator has no operating or display elements. 

Controller:

• 5 operating modes: Comfort, standby, night, frost/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/cooling units
• Controller can be de-activated (dew-point operation) or controller or operation of the controller can be blocked
• Automatic frost protection (detection of sudden drop in temperature) for use without window contact
• 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)
• Temperature detection via an internal and/or external sensor (average value calculation for large areas)

Inputs:

• Free assignment of the functions switching, dimming, blind and value transmitter to the inputs
• Blocker for blocking individual inputs
• Behaviour when the bus voltage returns can be configured separately for each input
• Telegram rate limiting
• Switching function: Two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, SW, no reaction)
• Dimming function: Single 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, CHANGE), operating concept can be configured (Step - Move - Step or Move - Step), time between step and moving mode can be set, slat adjustment time can be set
• Value transmitter and light scene auxiliary unit function: Edge (push button as NO contact, push 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
• Temperature sensor function: On channel of the push button interface can be used as an external temperature sensor for the room temperature controller.

Outputs:

• Independent switching of a maximum of 2 outputs
