13 46.100/2 RDT 100 Operation The RDT 100 controller has software modules with fixed configurations and captive standard parameters. When selecting the control model, the software modules are linked to (for instance) a cascade controller with sequence output and shift. There are also modules for min./max. limitation, selection and external setpoint. All user parameters can be stored in the optional memory for documentation purposes or for copying when installations are similar. All parameters are captive. The sliding switch (Hand/Automatic/Service) controls the operating modes. Service In this mode, the controller is matched to the control task by selecting the appropriate control model, and the inputs and outputs and the additional functions are configured. Automatic Control mode with setpoint Xs1 internal or external; Xs 2 internal only. On entering this mode, the prevailing positioning signals are adopted. They can be set manually between 0 and 100%. Any adjustments to the control parameters are made in the Hand mode.

Δp s [bar]= Max. permissible pressure difference across the valve at which, in the event of a malfunction, the close/off pressure drive can close the valve. The pressure difference across the valve in control mode that can overcome the force of the drive. In this mode, a reduced serviceable life can be expected. Cavitation, erosion and pressure surges may damage the valve. The values stated apply only when the valve is fitted on the drive. Sauter Components T3

18 VXN /3 Operation Using an electric drive, the valve can be moved to any position. The valve closes when the valve spindle is extended. Can close either against the operating pressure using the AVM 104/114/124(S) actuator or the AVF 124(S) actuator with spring return. Closing with the operating pressure only with AVM 124(S) and AVF 124(S). The valve spindle is fixed to the drive spindle. This enables the valve to close either with or against the operating pressure. It also stops the plug from flapping about in the end position and, at the same time, hinders cavitation and erosion. Because there is no opposing spring pressure when the valve closes, the full force of the drive is available for the permissible pressure difference. Engineering and fitting notes The manual adjuster (accessory) is fitted onto the valve like a drive. The connection to the valve spindle is effected automatically when the valve is opened with the button. The control unit can be fitted in any position except facing downwards. The ingress of condensate, drops of water etc. into the drive should be prevented. In order to restrain contaminants in the water (e.g. welding beads, rust particles etc.) and prevent the spindle seal from being damaged, we recommend the employment of collective filters, e.g. for each floor or feed pipe. The composition of the water should be in accordance with VDI The valve and drive can be assembled without having to be set up; the drive adapts itself automatically to the valve stroke and to the stops as soon as power is applied. To prevent the flow of the medium from being audible in quiet rooms, the pressure difference across the valve should not exceed 50% of the stated values.

Telephone Fax Internet Manor Green Road, Epsom, Surrey KT19 8RA Specification /08/06 Unit Code Capacity [litres] Cased Diameter [mm] Height [mm] IT IT High Capacity Thermal Buffer System with Solar and UFH The system is designed to make maximum use of a boiler, solar panels, and UFH, where there is a desire to use solar as a heat source for the UFH where possible. The boiler is only called to provide heat for UFH if the flow from the cylinder drops below 55 C (installer/user adjustable). To recover the top section of the store for hot water, typically to C, the system uses a second cylinder thermostat, fitted higher than the first. The store, the boiler circuit, and the UFH circuit are all integrated in a single pressurised system, suitable for a maximum working pressure of 10 bar, but typically filled to 2 bar. Combining the systems this way allows for greater utilisation of boiler output, and overcomes additional temperature drops between the store and the UFH circuit when running on solar. Domestic hot water is provided at full mains pressure using the Hi-Flow heat exchanger assembly. Each assembly can provide up to 45 l/min of hot water, and more than one can be fitted if higher flow rates are required. Additional controls will be required (not shown) for high temperature isolation of boiler and solar panels under overheat conditions. Electric Immersion Heaters are optional, with the single flanged boss able to take heaters up to 30kW in single or three phase.

A feed and expansion tank is required at high level. Domestic hot water is provided at full mains pressure using the Hi-Flow heat exchanger assembly. Each assembly can provide up to 45 l/min of hot water, and more than one can be fitted if higher flow rates are required. Additional controls will be required (not shown) for high temperature isolation of boiler and solar panels under overheat conditions. Electric Immersion Heaters are optional, with the single flanged boss able to take heaters up to 30kW in single or three phase.
