INSTRUCTIONS Type MCS4/OCS4-10 67022D 07/16 (LOA) MCS4-10 OCS4-10 English CENTRAL CONTROLLER, CS4TM Comfort System4™ is a complete control system for electric heating in your house. The Central Controller is the master thermostat, which controls and monitors all the thermostats and relay modules in the different rooms, up to 32 rooms. All thermostats and relay modules in the Comfort System4™ are programmed from the Central Controller. You can groupe the units in the house with up to 5 different time schedules from the Central Controller. The time schedules are pre-programmed for easy Plug & Go installation. The Central Controller features a built-in room sensor and is supplied with a floor sensor for controlling the floor heating in the room concerned. PRODUCT PROGRAMME MCS4/OCS4-10 Central Controller with build-in room sensor, incl. floor sensor WARNING – Important Safety Instructions Disconnect the power supply before carrying out any installation or maintenance work on this unit and associated components. This unit and associated components should only be installed by a competent person (i.e. a qualified electrician). Electrical installation must be in accordance with appropriate statutory regulations. INSTALLING THE CENTRAL CONTROLLER The unit is designed for flush mounting in a wall socket. A baseplate for external wall mounting is available. Fig. 1: 1.Slide the power button down to Off “0”. 2.Release the front cover ONLY by inserting a small screwdriver into the hole on either side of the thermostat. Fig. 2 + 2a: 3.Connect the wires in accordance with the diagram. 4.Mount the thermostat in the wall socket. Please ensure that the adapter plate is properly clipped on the thermostat. 5.Fit the frame and carefully press the cover onto the thermostat. Ensure that both the power slide button on the cover and the power switch pin are down. DO NOT open the controller by releasing the four fixing clips on the back. MOUNTING OF SENSOR The terminals for the sensors contain a safety extra-low voltage (SELV) circuit, allowing the sensors to be placed as close to the floor surface as necessary without the risk of electric shock, should the sensor cable become damaged. Sensor cable recommendations • The sensor cable may be extended up to 30 m by means of a separate two-core cable. • The two wires from the sensor to the thermostat must be kept separate from high voltage wires/cables. Place the cable in a separate pipe or segregate it from power cables in som other way. Never use two vacant wires in a multi-core cable. • Shielded cable: Do not connect the shield to earth (PE). Fig. 3: Mounting of floor sensor The floor sensor is used for comfort temperature regulation in rooms on the basis of floor temperature. It is recommended that the cable and sensor be placed in a non-conductive installation pipe embedded in the floor. The end of the pipe must be sealed and the pipe placed as high as possible in the concrete layer. The floor sensor must be centred between loops of heating cable. PLACING THE THERMOSTAT. The room sensor is used for comfort temperature regulation in rooms. Fig. 4: The thermostat should be mounted on the wall approx. 1.6 m above the floor in such a way as to allow free air circulation around it. The thermostat must never be covered by a curtain or similar. Draughts and direct sunlight or other heat sources must be avoided. Fig. 4a: Observe the minimum distance of 0,5m, from large metal surfaces, electronic equipment, electric motors, etc. Fig. 4b: To ensure good wireless transmission without interference, all wireless units in the Comfort System CS4TM should always be placed with min. 1,0m between them. SETUP CENTRAL CONTROLLER The first time you switch the power interrupter to ON “I”, basic settings must be set. The menu will automatically guide you through the process. 1.Choose “language”, “time” and “date” with the up and down buttons and confirm with OK. 2.“Please select schedule for this thermostat” Name the time shedule with a specific name from the list called “Zone” and confirm with OK. 3.“Please activate thermostats for connection” You can now connect the thermostats/relay modules in the system to the Central Controller. Confirm with OK. PROGRAMMING See user manual for CS4TM for further options and how to plan you system. FIG.5: SENSOR RESISTANCE If the sensor is disconnected or short-circuited, the heating system is switched off. The sensor can be checked against the resistance table. ERROR CODES / STATUS E0:Internal error. The unit must be replaced. E1: Built-in sensor fault. E2: External sensor fault. E5: Internal overheating. Inspect the installation. E6: Communication error. E8: Wrong application in the thermostat or the time schedule.
