Technical Description User Friendliness Our new CONDUCTOR in-house developed room control equipment is a natural result of our efforts to provide the user with a healthy indoor climate. Different rooms have different requirements, and this has motivated us to develop various applications. These applications are principally developed for the climate control of waterborne climate systems in offices, hotels, hospitals and conference rooms. This is more clearly described under the different applications: W1 (office with constant airflow), W3 (Hotel with occupancy-controlled airflow), W4.1 (Hotel/office...

Control function: Power supply: Inputs: Outputs: Communication: CONDUCTOR W1 Office with constant airflow The CONDUCTER W1 room control equipment is designed for controlling the indoor climate in offices. Since the room environment should be invigorating, and offer the highest degree of comfort possible, uniform temperature and a healthy indoor climate are significant necessities, regardless of the outdoor temperature and season. Individual variations in room level are also significant necessities. Digital controller, room unit, handheld terminal, thermoelectrical actuators, valves, cables and...

CONDUCTOR W3 Hotels or hospitals with occupancycontrolled airflow in fixed steps. The CONDUCTOR W3 is an application specially designed for controlling the indoor climate in hotel rooms and hospitals. Since the room environment should be peaceful, quiet and offer the highest degree of comfort possible, uniform temperature and a healthy indoor climate are significant necessities, regardless of the outdoor temperature and season. Individual variations in room level are also significant necessities. During certain times of the year, high humidity may also involve risk of condensation. CONDUCTOR...

CONDUCTOR W4 Situation-adapted, demand control of air, cooling energy and heating for maximum energy saving. CONDUCTOR W4 is an optimized application for controlling waterborne cooling and heating in combination with supply air. The W4.2 is able to control two supply air dampers and one extract air damper and is mainly intended for use in conference rooms. Since the number of occupants in conference rooms is relatively low while the number of people present at the meetings varies from meeting to meeting, a situation-adaptable indoor climate system is required for creating a healthy room climate...

CONDUCTOR Water first/then air Adaptable commissioning When the room is occupied, the room temperature is first regulated mainly by means of waterborne cooling. If waterborne cooling is not enough, the air volume is variably increased until the room air reaches the required room temperature. The air volume is regulated at the same time according to the CO2 level. If the CO2 level should exceed the preset max. permissible value, the controller will increase the airflow regardless of whether this is needed for regulating the room temperature for the purpose of ensuring proper air quality. If the...
