AS2012 Kit (for Older Boiler Design)

Product detailed description

Sensors and probes for coordinating the buffer tank, burner and boiler - AS2012 Kit (for older boiler design).

- used to control the A 25/A 45 burner of a boiler fitted with an induced-draught fan, a boiler-circuit pump or a solar heating pump, based on the temperatures of three sensors on the buffer tank with a solar heat exchanger and in cooperation with a sensor on the solar panel. The set of four sensors consists of three KTF20 water sensors with a 6m cable and one flue-gas (solar) sensor up to 400 °C with a 5 m cable, a solar pocket/well, four tin connector sleeves for quick wire connection, an AD 03 module for controlling the boiler's induced-draught fan and the boiler-circuit (solar) pump from the A 25 burner, and one connector for the DCxxSP(X), CxxSP boiler. This kit is designed for DCxxSP(X), CxxSP boilers (up to serial number 343500) with the function of automatically starting the pellet burner after the log wood has burned out, or for the DxxP boiler with the function of controlling the burner according to three temperatures on the buffer tank with a solar heat exchanger.

Note: For the 2018 model design of the DCxxSP(X), CxxSP boilers, it is sufficient to additionally purchase just one AGF2 solar sensor and one KTF20 sensor with a 5 m cable for the solar function.

FAQ

• How can I verify that "AS2012 Kit (for Older Boiler Design)" fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation from your appliance's (boiler, tank, water heater) rating plate with the compatibility stated directly in this product's name (brand Atmos) and in its technical parameters above. If in doubt, send us the exact type designation of your appliance (including the serial number, if available) - we will be happy to verify compatibility for you.
• Why is it important to use an original/compatible part rather than a universal replacement? Parts such as seals, sensors or safety components (safety valves, thermal fuses) are usually dimensioned precisely to the parameters of a specific appliance (pressure, temperature, sensor electrical resistance) - the wrong part can cause reduced function, leaks, or in the case of safety components, a real safety risk.
• Does installing this part require a professional? For simpler, mechanical parts (e.g. seals, covers, small accessories not connected to electricity, gas or the pressurised part) a handy DIY person can usually manage the replacement after disconnecting the appliance from power and the mains. However, for any intervention in the gas, electrical or pressurised part of the appliance (e.g. sensors located directly in the combustion chamber, safety valves, electronic modules) we always recommend a service technician - especially since such work could affect the validity of the warranty on the whole appliance.
• How do I know this part is worn and needs replacing? Common signs are visible wear/cracking (for seals and rubber parts), a leak of water or flue gas at the part, an error message on the controller display (for sensors and electronic modules), or an obviously reduced function of the appliance (e.g. irregular combustion for burner parts). If in doubt, the safest option is to have the condition assessed by a service technician during the regular annual inspection.
• Is it worth keeping this part at home as a spare? For parts that are subject to normal wear (seals, fuses, small mechanical parts) and whose failure would mean a heating or hot water outage, keeping a spare on hand is a sensible precaution - especially for an older appliance for which the part may be harder to source quickly.
