The room temperature controller is part of the „Millenium KNX sensor program. It is a monoblock application
module which is suitable for installation in flush-mounted boxes according to BS 4662:2006+A1:2009. The device
is equipped with an integrated bus coupler.
The room temperature controller senses the current room temperature and regulates the heating or cooling. The
device also serves to control two-/four-pipe systems (2-/4-pipe fan coil units) and conventional air-conditioning
units. Additionally, further switch-control telegrams can be sent to KNX actuators to activate a connected
ventilation fan
Hotel management systems can gain direct access to the room temperature controller via KNX and activate
controllers in the room. The fan speed level can also be selected manually via a buttons (forced operation). This
makes it possible to very quickly adjust the temperature in a hotel room to the individual wishes of the guests. The
device supports the full function for international hotel applications. It can function in the operating modes
"heating/cooling", "only heating" and "only cooling".
For operation and display, the room temperature controller is equipped with push-buttons and a rotary control
element. An LCD display serves to indicate the current operating states and values. The use of simple symbols on
the buttons and in the display allows the room temperature controller to operated easily and intuitively.
The device has four control buttons:
• Fan speed level
Button function is freely parameterizable (switching, dimming, etc.)
• ECO mode
• Room temperature controller On / Off
The following table lists the options for use:
Special features
• Function illumination
• Freely programmable
• Day / night switchover of the LEDs
