HYDRAULIC SCHEMATIC Flow Flow Zone 1 Zone 2 Return Flow Cold Water Inlet Return Return Zone 1 Zone 2 UNVENTED INSTALLATIONS Failure to fit these essential safety devices will invalidate the warranty and create a dangerous installation. This may lead to property damage, injury or loss of life. Thermostatic control — The in-built immersion heater contains a high limit thermostat which is factory pre-set to 60°C. This Energy Cut Out Device should not be removed or bypassed. -
Page 7: Discharge Pipes From Safety Valves
DISCHARGE PIPES FROM SAFETY VALVES 3.5.1 TUNDISH INSTALLATION The discharge pipes must be routed to a tundish. The pipe diameter must be selected from the table below. For D1 (Valve to tundish), at least 15mm piping must be used. For D2 (downstream of the tundish), include the resistance created by each elbow or bend when calculating the length, and select an appropriate pipe size according to table 3 below. -

Disconnect the electrical supply prior to starting any work on or opening any cover on the Inoxstor. SYSTEM WIRING The Inoxstor is designed for use with Immergas Audax Air to Water heat pumps. An outline schematic of the system wir- ing is shown below. Audax Min C.S. -
Page 9: Audax Control Wiring
AUDAX CONTROL WIRING The Inoxstor is pre-wired and configured for use with two heating zones in addition to the provision of hot water. On the Inoxstor, the following is pre-wired: ▪ Audax Remote Controller ▪ Zone valves - Zone 1 and 2 ▪ Three way valve ▪ Hot Water Sensor ▪ Anti-legionella timer and Immersion Connect the Audax interface board on the Inoxstor to the Audax using three no cables: •... -
Page 10: Thermostat Wiring
THERMOSTAT WIRING The Audax interface board has two connectors marked TH1 and TH2 which may be used to control the Audax using a ther- mostat, chronostat, programmer or switch. Each of these terminals has four pins, three of which provide L, N, E, and a switched input. Applying 230V to the switched input will activate the zone valve and turn on the audax. -
Page 11: Control Using 230V Programmers
4.3.3 CONTROL USING 230V PROGRAMMERS Provide Live Neutral and Earth power supply from either TH1 or TH2. The 230V output for each zone should be applied to the SW pin on the TH1 or TH2 terminal. Terminal Power supply to programmer Power supply to programmer Power supply to programmer From zone 1 output on programmer... -
Page 12: Commissioning
COMMISSIONING It is important to follow the steps outlined below during commissioning of the Inoxstor. This refers to operation of the inoxstor itself. Read the Audax Instructions carefully for information on commissioning the heat pump and central heating circuit. Do not switch on the electrical supply or Audax Heat Pump until the unit has been filled with water and checked for leaks. Check that all installation, electrical and discharge pipe requirements have been met. -
Page 13: Checking The Operation Of Safety Valves
Repeat the procedure for the Temperature & Relief Valve, if installed. Note: The water discharged may be very hot. FILLING THE AUDAX AND CENTRAL HEATING SYSTEM Follow the Immergas Audax Instructions, "Installation of the Unit" section. Ensure that water quality guidelines are fol- lowed. -
