430294ENG-Jun02 Introduction 3 The RS-30 has the most modern technology and serves as a weather / room temperature regulator with integrated hot water control and remote operating functions for the UltraGas or Topgas boilers. 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 1 (user instructions) delivers all immediately important operating stages which are necessary for use and are selected with directly accessible operating keys. Part 2 (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.

It is possible to return to the default display at any time using the information key. 2 - Time clock level In the time clock level the individual program times can be customized. 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 stored 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 for 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 works setting of 20ºC or the corrected 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 therefore have to be recreated if needed.

430294ENG-Jun02 Advanced User Instructions 11 Room temperature correction for PARTY and HEATING with variable temperature parameter enabled. For operating types:

- PARTY - HEATING

The room temperature is set to automatic works setting of 20ºC or the corrected value which has been set in the user level. The actual room temperature values for 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 or HEATING by using the and keys. These values remain stored for each further call of this operating type. Time Clock Programming It is possible to program up to three cycles / periods for each desired weekday. 1 – Heating Cycle For heating each of these cycles has an on / off as well as a temperature indication for 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 according to the night temperature. 2 – Hot Water Cycle For 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 for each cycle. Entering the time clock level Entering this level is achieved by simply pressing the key. The program 1, 2 or 3 which is set in the room level is shown.

The heating curve gives the boiler 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 0.1 increments every 1 or 2 days is recommended.

Blinks if auto adaption is set in service level parameters (do not change)

22 Advanced User Instructions 430294ENG-Jun02 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. Recommended values: Floor heating: 0.3 ….. 1.0 Radiator heating: 1.2 ….. 2.0 Convection heating: 1.5 ….. 2.0 Heating curve graph
