2-2 Cold Draft Prevention (Heating Cycle)

The cold draft prevention function controls indoor fan speed so a strong draft of cold air will not blow out before the indoor heat exchange coils have warmed up.

STANDBY shows on the remote controller when the indoor fan speed is LL (very low) or OFF. This condition occurs in the following 3 cases:

During Thermo OFF (refer to 2-1 B). Room Temperature Control, Heating)

During the defrosting operation (refer to 2-10 Defrosting Control, Heating)

Until either the coil temperature E2 reaches 81°F or when a maximum of 6 minutes has past.

The indoor fan motor operates in L instead of LL for 3 seconds as it starts to give the fan an initial boost.

Chart Summary and Explanations

The main idea of this chart is to show that the indoor fan speed increases and gets closer to the set fan speed as the coil temperature E2 rises.

The indoor unit’s coil temperature is taken from sensor E2 located in the middle of the indoor heat exchange coil.

The dotted line shows that the indoor fan motor is OFF. When the temperature at sensor E2 falls below 50°F, the indoor fan motor stops running.

Sanyo XHS3632, XHS2432, CH2432, CH3632 service manual Cold Draft Prevention Heating Cycle

XHS3632, XHS2432, CH3632, CH2432 specifications

The Sanyo CH3632 is a cutting-edge air conditioning unit that exemplifies efficiency and innovation in climate control technology. Designed primarily for residential use, this model has attracted attention due to its combination of powering performance and user-friendly features.

One of the standout characteristics of the Sanyo CH3632 is its energy efficiency. With a high Seasonal Energy Efficiency Ratio (SEER), the unit consistently delivers cooling while minimizing energy consumption. This not only reduces monthly electricity bills but also contributes positively to environmental sustainability. Its environmentally friendly refrigerant further emphasizes Sanyo's commitment to eco-conscious designs.

The unit employs advanced inverter technology, which allows for variable-speed compressor operation. This means that instead of turning on and off, the compressor adjusts its speed based on the cooling needs of the space. This creates a more stable and comfortable indoor environment while ensuring quieter operation. The reduced noise levels make the CH3632 an excellent choice for bedrooms and living spaces where peace and tranquility are essential.

Another key feature of the Sanyo CH3632 is its dual filtration system, which combines a pre-filter with a HEPA filter. This system effectively captures dust, allergens, and other airborne particulates, ensuring that the air quality remains high. Homeowners can breathe easier knowing that their indoor air is cleaner and healthier.

Smart features are also integral to this model. The Sanyo CH3632 can be integrated with smart home systems, allowing users to control temperature settings via mobile apps or voice commands. This connectivity makes it convenient to manage cooling preferences from anywhere in the house, adding a layer of modern convenience to home comfort.

Installation of the Sanyo CH3632 is straightforward and can often be completed without extensive modifications to existing structures. Its sleek design allows it to blend seamlessly into various home aesthetics, making it an attractive addition to any space.

In summary, the Sanyo CH3632 is a highly efficient air conditioning unit that incorporates advanced technologies for optimal performance. With eco-friendly features, smart connectivity, and an emphasis on air quality, it sets a high standard for comfort in residential air conditioning solutions.
