Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure thatcustomers are provided with the correct equipment for their needs, that it is installed, commissioned andserviced in accordance with the manufacturer’s instructions by competent persons and that it meets therequirements of the appropriate Building Regulations. The Benchmark Checklist can be used to demonstratecompliance with Building Regulations and should be provided to the customer for future reference. Installersare required to carry out installation, commissioning and servicing work in accordance with the BenchmarkCode of Practice which is available from the Heating and Hotwater Industry Council who manage andpromote the Scheme.Visit www.centralheating.co.uk for more information.ContentsAVANTA PLUS System Options ON / Off Control (Internal modulating)1.

IMPORTANT NOTE:The layouts illustrated in this brochure are for guidance only and do not constitute a full system design. All Mechanical and Electricalequipment must be installed in accordance with the instructions supplied, by a suitably qualifi ed Engineer and to the currentregulationsControls for the AVANTA PLUS and AVANTA 12v/18v/24v BoilersThe AVANTA series are fully condensing boilers using gas / air ratio controls to provide full modulation and can be operated in thefollowing modes. All boilers require a permanent 230v single phase 3 amp fused power supply plus controls as below:NOTE:The boiler is phase / neutral sensitive when used with external 230v controls.ON / OFF Controlfi xed fl ow temperature where the boiler modulates it’s output to match a fi xed fl ow set point using simple 230v switching controls:• Single or Two channel time clock (internal only available on the 18s/24s/24c/30s/28c/35c/39c)• Room thermostat• Cylinder thermostat• Diverting / mixing or isolating valvesMODULATING Controlfl ow temperature is directly controlled by the outside weather or inside room compensator to provide comfort conditions at all timesusing “OpenTherm®” controls:• Outside sensor• DHW sensor or cylinder thermostat• Room compensator• Digital time/weather or room compensator• Mechanical time/ analogue weather or room compensatorControls available from Broag as optional extras• S62432 Internally mounted two channel digital time clock kit (not for the Avanta 12v/18v/24v)• S62432c Internally mounted single channel digital time clock (for the Combi series only)• 50153 Outside sensor• S43946 DHW sensor• S59475 Room thermostat - Celcia 10• S59161 Room compensator - Celcia 15• 58222 Wall mounted Digital Time / Weather compensator - Celcia 20 (outside sensor not included)• TG001 Wall mounted Analog Time / Weather compensator - Theben• DA001 Wall mounted two channel 24 hour time clock (230v switching)• DA002 Wall mounted two channel 7 day time clock (230v switching)• KT806 Wall wireless room thermostat kitTypical controls by others• External mounted simple two channel time clock providing, 230v switched supplies to time control heating and domestic hotwater eg. typical Honeywell ST699 or similar• Cylinder thermostat eg. typical Honeywell L641 or similar• Room thermostat eg. typical Honeywell T6360 or similar• HTG and DHW zone valves c/w a single end switch (closes on valve fully open) eg.

When using the AVANTA PLUS Combi boiler, DHW is always set for constant operation (not timed) but can if required be changedto allow for time restriction using a two channel time clock. If required the AVANTA series can report a common alarm or boiler runcondition to an external control panel or BMS by using the connections on terminal block X7.Terminals 1 and 2 - Common alarmTerminals 1 and 3 - Boiler run / external gas valve / external pump relayThese are both volt free (max capacity 230v 1 amp ) and are open contacts which close on common alarm or boiler run respectively(see Installation and Technical booklet for futher opions).Pre and After Sales ServiceOur dedicated pre-and-after-sales teams are ready to give you the support you need.
