Millenium 6124/08-981-500/AMD70053-AN Room Thermostat Controller

Product code: 613400309
The room temperature controller is part of the Millenium KNX sensor program. 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. The fan speed level can also be selected manually via a buttons (forced operation). 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. Requires Mounting Frame and Frame supplied as a separate part.
