Avanta suggested schematics

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.
