2 TECHNICAL SPECIFICATION Installation and Maintenance Please refer to the appropriate Product Manual. Connections Inlet and Outlet: 1 ¼ BSP standard. Flow Diagram 3 25 Standard: Hot inlet on right, cold on left, top outlet. Approvals Approved to ASSE117/CSA B125 WRAS approved (Water Regulations Advisory Scheme). Designed, manufactured and supported in accordance with accredited BS EN ISO 91:2 Quality Management Systems and BS EN ISO 141:24 Envitonmental Managenment Systems Operation In precisely controlling the temperature of circulating mixed water the Rada 32rmx performs two functions: Mixes hot water with cold and re-circulating water to a safe predetermined outlet temperature when any shower and washing points are in use. Maintains this temperature in the circuit when no draw-off is taking place. Flow Rate - l/min Flow Rate - l/min maintained Pressure bar Materials Base: Gunmetal, nickel plated. Cover assembly: Aluminium. Thermister cap: Phosphor Bronze Environmental Conditions Ambient temperature range: - 6 C. Ambient humidity range: - 1% R.H maintained Pressure bar The pressure loss/flow rate graphs are for the controller only at midblend and do not take account of pressure loss through check valves, in-line fittings, pipework or terminal fittings. When calculating the pump rate for the circuit allow.1bar for pressure loss through the Rada 32rmx at 1 l/min. Pressures Maximum static pressure: 1 bar. Maximum maintained pressure: 7 bar pressure loss. Performance Circuit temperature control: within ± 1.5 C of set temperature. Digital temperature display accuracy: ± 1 C within the range 3 C - 6 C. Electrical Supply voltage: 12 V AC via seperate transformer PT1 (1/11 V) or PT22 (22/24 V). Power consumption: 6 VA. Electronic circuitry protection: 5 ma quick-blow fuse (fitted). Cable entry: Base threaded to accept 2 mm conduit (not supplied). Applications The Rada 32rmx is designed primarily as the central temperature controller in the circulating system providing pre-mixed water for multiple shower and washing facilities where the hot water is supplied from a calorifier or stored hot water system. As can be seen from the schematic arrangement diagrams and the theoretical application diagram, this system can also allow both a high temperature circuit (for kitchens, laundries etc.), and a low temperature mixed water circuit for personal washing purposes to be supplied form the same low volume, high temperature type boiler thereby saving both space and energy. The Rada 32rmx can be used in schools, hospitals, factories, hotels, sports and leisure complexes, prisons, militray barracks, high rise buildings; in fact whereever water is required for showering or washing at safe, precise temperatures.

3 TECHNICAL SPECIFICATION Theoretical Application Diagram KEY * Where premises are under the regulatory Hot control of the Department of Health their guidance should be sought regarding the use Cold of re-circulating systems. Mixed Water Schematic Arrangement Unvented System High temperature circuit for kitchens etc. Key: See schematic diagrams opposite Temperature Selection and Control The improved accuracy possible with the Rada 32rmx control technology means that regardless of whether a circulating system is simply idling or maximum draw-off is taking place, blended water temperature drawn from the circuit will not vary by more than ±1.5 C of that set. The required temperature is set on site simply by adjusting an easily accessible setting screw on the controller body. It is maintained thereafter without the need for re-setting irrespective of changes in ambient temperature or in the temperature of hot and cold supplies. A 2 figure LED display on the controller housing gives a read-out of the mixed water temperature thereby providing an easy and positive means of setting the circuit. In addition, this digital readout has an intermittently-flashing display condition to indicate that the output blend temperature from the unit is out-of-range, i.e. that it is constantly outside ±1 C of the set temperature. This would normally advise of unsuitable supply conditions. How to get the best from the 32rmx The Rada 32rmx offers the capability of attaining a high accuracy of temperature control, both when outlets in the circuit are in use and when no draw-off is taking place. To achieve such control it is essential that: The circuit is designed and regulated in the manner prescribed The Rada 32rmx is installed in accordance with the installation instructions supplied with the product. High temp. circuit 7.5m minimum Optional to first outlet By-pass Valve Outlets Hot Pressure Water Relief Valve Blend Circuit Gate Valve F Pump Rada 32rmx Cold Main Pressure Reducing Valve Vented System Stop Valve Cold Main Cold Cistern High temp. 7.5m minimum circuit to first outlet Outlets Optional By-pass Valve Blend Circuit Hot Water F Pump Rada 32rmx Direct reading flow Strainer Lockshield Valve Gate Valve Check Valve F measurement and Mira Thermometer setting valve Cold Water Hot Water Mixed Water Six Critical Requirements Temperature Drop/Minimum Circuit Return Flow Rate A temperature drop around the circuit of at least 2 C is essential to allow the controller to modulate. Monitor by checking the thermometer at the end of the circuit return with the thermometer at the first drawoff point (It is recommended that these two thermometers are calibrated against one another by first putting them in ablutionary temperature water to establish any variances). A minimum circuit return flow rate of 1 l/min, set under idling conditions, is required to create the necessary mixing turbulence in the controller (Higher circuit return flow rates are permissible provided they do not prevent a 2 C temperature drop around the circuit). The use of a flow measuring and setting valve is recommended to ensure that this minimum circuit flow always exists. Auxiliary Fittings Other fittings required in the circuit, particularly check valves and gate valves, must be positioned as shown in the schematic diagrams. With the exception of 11/4 Rada check valves at the hot inlet of the Rada 32rmx and on the cold water supply, their size will depend on the pipe diameters necessary to meet the flow rate demands of the circuit. High Temperature Circuit Return If the hot water storage is also used to supply a high temperature circuit, as shown, this must return to storage after the check valve on the return from the mixed water circuit to prevent high temperature water entering the mixed water circuit. The high temperature circuit must be fitted with a check valve in the return to prevent mixed water entering this circuit. Water Pressure After allowing for frictional losses through check valves, in-line fittings, pipework and terminal fittings, the available remaining pressure should be sufficient to cater for the maximum draw-off rate allowing for diversity of use..

4 TECHNICAL SPECIFICATION Note! The pressure loss/flow rate graphs shown overleaf refer only to the Rada 32rmx at mid-blend temperature. The cold feed to and outlet pipework from the hot water storage should be sized to ensure that the inlet pressures to the Rada 32rmx remain nominally equal when there is a demand for hot water elsewhere in thebuilding. First Outlet The first draw-off point on the circuit must be at least 7.5m minimum after the Rada 32rmx to ensure complete water mixing. Electrical The Rada 32rmx requires 12V AC. supply. A separate transformer is available for this purpose, reference Rada PT1 (1/11V) or PT22 (22/24V). SAFETY FEATURES: Should the power supply to the valve be interrupted the proportioning mechanism automatically moves to the full cold position, thereby shutting down the hot supply to the circuit. On resumption of power supply the Rada 32rmx will resume normal operation. The Rada 32rmx transformer and circulating pump should be wired into the boiler programme to ensure that the valve and pump are only operative when hot water is available. Additional Considerations Circuit By-Pass It is good practice to make a by-pass connection between the hot water feed to, and the outlet side of, the Rada 32rmx. The opening of the lockshield gate valve in the be wired into the boiler programme circuit to ensure that by-pass permits the temporary use of the circuit during Rada 32rmx maintenance, albeit with uncontrolled temperature. Safety Precautions Under normal operating conditions, the Rada 32rmx automatically compensates for changes in the temperature and pressure of hot and cold supplies and is designed to shut down the hot water supply should either the cold water or power supply fail. Where additional safety precautions are advisable such as in institutions for handicapped persons, it is recommended that a failsafe device be installed as a further safeguard. A solenoid valve, which stays open when energised should be fitted on the hot supply to the Rada 32rmx and controlled by a thermal switch fitted immediately prior to the first draw-off point. The Rada 32rmx transformer should also be controlled by this switch, i.e. wired in parallel with the solenoid valve. Electrical Input Voltage: 23V 5/6Hz. Output Voltage:13.5V ± 5% at 44mA continuously rated. Regulation: Better than 28%. Protection: 13 C self-resetting thermal cut-out in primary winding.
