HONEYWELL Draught Regulator

Product detailed description

Honeywell draught regulator for ATMOS boilers

A mechanical thermostatic regulator that controls boiler output without electricity. It senses the flow water temperature and, via a chain, continuously closes or opens the air inlet damper to the combustion chamber – the hotter the water, the less air the boiler receives.

Application

The regulator is fitted into the boiler's weld-in socket and connected to the control damper by the chain. It is used, for example, on ATMOS DC18S gasification boilers. After replacement, set the chain length according to the instructions so that the damper just closes when the required temperature is reached.

Frequently asked questions

• How can I verify that the "HONEYWELL Draught Regulator" fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation from the rating plate of your appliance (boiler, storage tank, water heater) with the compatibility stated directly in the name of this product (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 applicable) - we will be happy to verify compatibility for you.
• Why is it important to use the original/compatible part rather than a universal substitute? Parts such as seals, sensors or safety components (safety valves, thermal fuses) are generally sized precisely for the parameters of the specific appliance (pressure, temperature, electrical resistance of the sensor) - an incorrect part can cause reduced functionality, leaks, or, in the case of safety components, a real safety risk.
• Must this part be installed by a professional? For simpler, mechanical parts (e.g. seals, covers, small accessories with no connection to electricity, gas or the pressure circuit), a skilled DIY enthusiast can usually manage the replacement after disconnecting the appliance from the power supply and the piping. However, for any intervention in the gas, electrical or pressure part of the appliance (e.g. sensors directly in the combustion chamber, safety valves, electrical modules), we always recommend a service technician - especially if the intervention could affect the warranty of the entire appliance.
• How do I know this part is worn and needs to be replaced? Common signs are visible wear/cracking (on seals and rubber parts), water or flue gas leakage at the part, an error message on the control display (for sensors and electronic modules), or clearly reduced functionality of the appliance (e.g. irregular combustion with burner parts). If in doubt, it is safest 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 normally subject to wear (seals, fuses, small mechanical parts) and whose failure would mean a shutdown of heating or water heating, keeping a stock is a reasonable precaution - especially for an older appliance, for which it may be harder to source the part quickly.
