430294ENG-Jun02 Introduction 3 The RS-30 has the most modern technology and serves as a weather / room temperature regulat with integrated hot water control and remote operating functions f the UltraGas Topgas boilers. With the most up to date micro electronics exclusive functions can be activated which guarantee the highest level of comft 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 infmation 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 f user and advanced user levels. The instructions are separated into two parts. Part 1 (user instructions) delivers all immediately imptant operating stages which are necessary f use and are selected with directly accessible operating keys. Part 2 (advanced instructions) these should only be used by the advanced user service engineer and relate to specific settings / heating parameters and are accessible by the covered operating keys.

Standard heating programs 1, 2 and 3 can be called up as desired and overwritten with different switch times and temperatures. Each standard program can thus be configured individually and sted under the same program number so that three different programs are available on demand. These can then simply be called up in the user operating level see page 6 f setting of the automatic program. Note: Programming of room temperatures is only possible if the relevant parameter has been enabled in the service level by an engineer. If this has not been done it is only possible to change the on / off times. In this case the room temperature will be the wks setting of 20ºC the crected value which has been set in the user level. The standard programs are lost when overwritten by customized programs. These are cancelled after a reset and replaced by the standard programs and therefe have to be recreated if needed.

Press key Boiler circuit Wks setting program 2 Boiler circuit Room level set to program 1 The actual room temperature values f each of these two operating types can be set independently to the automatic program if the relevant parameter has been enabled in the service level by an engineer. The value is set separately when calling up the operating type PARTY HEATING by using the and keys. These values remain sted f each further call of this operating type. Time Clock Programming It is possible to program up to three cycles / periods f each desired weekday. 1 Heating Cycle F heating each of these cycles has an on / off as well as a temperature indication f this time span. The temperature can only be adjusted if the relevant parameter is enabled in the service level. Between heating cycles the room temperature is regulated accding to the night temperature. 2 Hot Water Cycle F hot water each of these cycles has an on / off time. Between hot water cycles hot water heating is switch off. The temperature is set in the room level and cannot be changed f each cycle. Entering the time clock level Entering this level is achieved by simply pressing the key. The program 1, 2 3 which is set in the room level is shown. Boiler circuit Room level set to program 3 With the and the heating hot water circuit can be called up and is available f programming. Calling up of heating cycles With a further pressing of the key the first heating cycle of the selected program shows complete with indication of weekday, cycle number, on time, off time and temperature. Each value is called up with the key in series The - On time - Off time - Temperature key can be used to step backwards. The current value which can be changed with the and keys is shown blinking. Switch times can be altered in 5 minute intervals and temperatures in 0.5K increments in the range of 5-30ºC. The next heating cycle can be called up by pressing the key and the process repeated. Note: The on/off times of not used heating cycles should be set to 00:00 by simultaneously pressing the and keys. The 00:00 value does not refer to a clock time but only shows an undefined switch time. After programming the last heating cycle (Sunday cycle 3) the first heating cycle (Monday cycle 1) will follow.

Positioning with room sens When used with the unit sens activated the unit must be placed at a height of approximately 1.20 to 1.50 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, radiats etc. On walls where hot water pipes chimneys run. On outside walls which are not insulated. In cners, recesses, shelves behind curtains (insufficient air circulation). Near dos 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) 2x0.6 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 Befe connecting / wiring the power at the boiler must be off. The 2 ce 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. Refer to the electrical diagram supplied with the boiler.
