KTRRB-117.169, room temperature controller, heating / cooling, plaster, 230 VAC, 3-stage fan output 0... 10 V or dynamic 0... 10 V

Room temperature regulator, heating / cooling, plaster, 230 VAC, 3-stage fan output 0... 10 V or dynamic 0... 10 V

The KTRRB-117.169 air-conditioning controller has been specially developed for the control of EC- blower convectors, EC- fan coils and other EC-fan-supported air-conditioning systems in 2 or 4-pipe systems with current-free closed valves. The KTRRB-117.169 is used as a single room temperature controller with internal sensor or as an external control unit with optional remote sensor. The optional external flow sensor is used for automatic switching of the controller in heating or cooling mode in 2-pipe operation, depending on the flow temperature, alternatively this input can be used as H / K switching contact. 3-stage fan output 0-10 V with adjustment of the individual fan stages or dynamic 0-10 V for the control of EC fans. Ventilator operation in neutral zone AN / OFF can be selected. In the case of a sensor break or a fuse, the heating is controlled with a 30% switch-on time to avoid cooling or freezing damage in the room. With an internal switch, the available contact input can be configured as an EC contact or a standby contact. ECO- function: If this function is chosen, it is controlled in the heating operation to a 3K lower and in the cooling operation to a 3K higher temperature. Standby function: If this function is selected, the controller is switched off (frost protection continues to be active). For cleaning / wall mounting or by means of an adapter plate on a UP can.
