- Pay attention to the warnings in the installation and user manual. This way, misuse and the hazards
caused by it will be prevented.
- General maintenance of your appliance should be done each year at the beginning of the season.
Make sure to have E.C.A authorized services carry out maintenance procedures.
- Cleaning of the outer surfaces of the appliance should only be done with a damp cloth without using
detergent or any chemicals. Use of chemicals such as detergents etc. can cause corrosion and
contamination of your appliance.
The E.C.A KRONOS PT 24 room sealed combi boilers are intended for central heating and domestic hot
water use. KRONOS room sealed combi boilers work with natural gas.
With its design that makes service and maintenance easy, and dimensions of 720x400x330 mm, it
saves space in the places of use. It has an elegant look with its rounded lines and design.
The control panel is designed in an ergonomic structure. The operating functions, central heating
circuit and domestic water temperatures, fault status setpoints in case of possible faults, water
pressure information and current values can be viewed on the LCD.
The appliance's operating functions and safety are achieved from a single center, ‘controlboard’. The
controlboard controls the gas valve, fan, circulation pump and the 3-way valve. Presence of flame in
the burner can be monitored on the LCD screen.
The burner is made of stainless steel material resistant to temperature and thermal stresses. It works
quietly with its special design, and provides efficient and clean combustion as a result of homogenous
distribution of the gas. A perfectly insulated combustion chamber is designed in ideal dimensions
according to the burner, providing high efficiency and low gas emissions with minimal heat loss. In
addition, an aluminum recuperator has been used to transfer the thermal energy obtained by
lowering the waste gas temperature to water. In this way, more efficient operation of the device is
ensured. These features of the burner, the recuperator and the combustion chamber ensure fuel
efficiency and minimum noise level.
Three-speed circulation pump has an automatic purge valve and suitable for all installations. The
appliance has a 'pump over-run' feature that prevents heat accumulation at the installation. With this
feature, the circulation pump continues to run for a certain period of time after the need for central
heating and/or hot domestic water has ended.
High efficiency is achieved with a long-life, copper heat exchanger designed as thermal shock
resistant. In addition, there is a steel plate heat exchanger in the appliance to obtain comfortable and
efficient domestic hot water. Therefore, the installation water and the domestic water never mix.
With the safety systems in your appliance, both you and your appliance are fully safe. These safety
systems;
• Flue Safety
• Blowout Safety
• Overtemperature Safety (105°C)
• Domestic Water Overheating Safety (71°C)
• Central Heating Circuit Water Overheating Safety (95°C)
• High Water Pressure Safety (3 bar)
• Low Water Pressure Safety (0,8 bar)
• Low Voltage Safety (160V AC)
• Hot Water Accumulation Safety (by-pass cycle and pump over-run)
• Frost Safety (the electrical connection of the appliance must not be cut-off in order for the frost
safety to work.
• Pump Anti-Sticking Safety
• 3 Way Valve Anti-Sticking Safety
• Automatic Air-Purge Valve
• Expansion Tank
• Siphon Blockage Safety
