409ENG-Dec0 Introduction The TopTronic RS-0 room station serves as a decentralized information center with remote interrogation and remote operating functions and can be used with all equipment versions of the TopTronic system. With the most up to date micro electronics exclusive functions can be activated which guarantee the highest level of comfort with the minimum energy usage. This is achieved with adaption and optimization functions which match heating energy to the exact building requirements. As well as these room temperature related functions a variety of equipment specific information is available which can be read within the living room and when necessary adapted to individual circumstances. This encompasses dates, on/off switching of the heating cycle with differently regulated room temperatures, actual values and diagnostic fault messages of the boiler. Operation of the unit is easy to understand and is limited to a minimum of operating elements which are separated for user and advanced user levels. The instructions are separated into two parts. Part (user instructions) delivers all immediately important operating stages which are necessary for use and are selected with directly accessible operating keys. Part (advanced instructions) these should only be used by the advanced user or service engineer and relate to specific settings / heating parameters and are accessible by the covered operating keys.

Advanced User Instructions 409ENG-Dec0 Works setting:.4 Range: 0.0.5 Change with or With this parameter it is possible to change the slope of the heating curve for the boiler circuit (see graph). The heating curve gives the (boiler and / or mixed circuit) flow temperature / outdoor temperature ratio. The curve should only be reset with minimum changes spread out over a certain period of time to enable the regulator to react (by nature a heating installation is very slow to react). Corrections of 0. increments every or days is recommended. Note: The room station should be placed in the room that most accurately represents the temperature of the building. Thermostatic radiator valves when fitted properly should only serve to deregulate foreign heat sources and therefore should be fully open. During the regulation phase all foreign heat source should be switch off and ventilation should be kept to a minimum so as not to disturb the regulation process. When the heating curve is correctly set the room temperature should remain constant regardless of outside temperature. If automatic adaption is set in the service level the value will blink and is constantly corrected. In this case it must not be manually altered.

409ENG-Dec0 Installation / Technical Data 7 Installation Positioning without room sensor If there is no room sensor or the room sensor has not been activated the unit can be placed as desired. Positioning with room sensor When used with the unit sensor activated the unit must be placed at a height of approximately.0 to.50 m in a place representing the temperature of all rooms. It is advisable to choose an internal wall in the coolest room which is used in the day. The unit may not be positioned: In direct sunlight (take note of the position of the sun in winter) Near any equipment which produces heat like televisions, wall lights, radiators etc. On walls where hot water pipes or chimneys run. On outside walls which are not insulated. In corners, recesses, shelves or behind curtains (insufficient air circulation). Near doors which lead to unheated rooms. In rooms which are regulated with thermostatic valves. Mounting Open the cover and loosen the screw inside. Lift the unit off the back plate. Secure the back plate with the screws provided. The data bus cable must be threaded through the lower part of the back plate. With a data bus cable of over 50m cable of types JY-(ST) xx0.6 or LI YC T (TP) xx0.75 must be used. The screening must be connected to the earth terminal of the boiler. Note: on new installations use a box behind the room station. Electrical Connection Before connecting / wiring the power at the boiler must be off. The 4 core bus cable is connected to the 4 pole terminal on the back plate. After the wiring is complete the room station is slotted in from above and screwed to the back plate. Note: by incorrect wiring the remains in VERSION indication for approximately minute and then goes to fault indication. Technical Data Wiring: 4 pole screwed terminals on back plate for mm max wire cross section. Bus Interface: RS485 Power supply: From central unit Color: White RAL 906 Fixing distance: 60mm ( hole fixing) Wall Fixing: x mm dia x 8 long Weight: 70g Operating Temperature: -0 o C.+50 o C Storage Temperature: -5 o C.+60 o C Indication: Alpha numeric text indication as well as symbols
