Heat Pump With Electric Heat Operation (Continued)

Condition 2

If the Δ (delta) (set point temperature minus the ambient indoor temperature) is greater than 5 ˚F, then the unit will switch to electric heat, if available. The unit will continue to operate with electric heat until the heat demand is satisfied. Note that the electric heat switches on after the Δ temp passes 5°F and the heat pump switches off. Also note that the electric heat will run until the heat demand is satisfied. When another heat demand cycle is initiated, the heat pump will run unless the Δ temp is greater than the electric heat threshold.

Automatic Emergency Heat

If the sealed system fails with a bad reversing valve or anything that causes the indoor coil to get colder than the indoor ambient temperature:

1)If the indoor coil thermistor senses a 5 degree temperature drop as compared to the ambient temperature thermistor and this lasts up to 5 minutes, the control board will switch the unit to electric heat and continue heating with it.

2)At this point, error code 15 is generated; heat pump failure. Indoor coil temperature lower than indoor ambient temperature for 5 or more degrees for 5 consecutive minutes.

Note: It is Ok to continue to use the unit with the electric heater until the heat pump is repaired.

Electric Heat Operation in Cool with Electric Heat Units

When in the Heat mode, with and without Fan Mode Auto (Fan cycling):

If the indoor ambient temperature is below the Heat Demand Threshold (Heat Set Point minus 1.5 ˚F), turn on electric heat. If Ambient is 0.3 ˚F above the Heat Set Point turn off the electric heat.

System Mode Auto

This mode provides automatic change over between cool and heat. The auto mode runs based on the room ambient temperature vs. the Demand Thresholds. It is only available in Heat-Cool Unit.

Notes:

There is a buffer zone between the cool and heat set points where no heating or cooling is allowed to occur. It is critical that the Cool Demand Threshold be greater than the Heat Demand Threshold by a minimum of 3° while in the Auto System Mode. For example, if a user enters a value for the Auto Cooling Set Point that violates the minimum Δ 3° rule, the Auto Heating Set Point will adjust accordingly.

Automatic Change Over Delay (Cool with Heat Units)

The change over delay ensures that any system heating or cooling over shoot does not trigger an opposite demand cycle. The change over delay = 15 min. This timer blocks the opposite demand cycle from running until the timer expires. As an example, if the last demand was a cool cycle, and another cool cycle is requested, the timer will not block the request.

However, if the last demand cycle was a cool cycle, and heat cycle is requested, the timer will block the request until the

change over delay is expired.

SM18N30*, SS10N10*, SS15N30*, SS12N10*, SS14N10* specifications

Friedrich air conditioners, particularly models SS14N10*, SS12N10*, SS15N30*, SS10N10*, and SM18N30*, are renowned for their reliable performance, innovative technologies, and user-friendly features. Designed for both residential and commercial use, these units stand out due to their energy efficiency, advanced cooling capabilities, and versatile operation.

One of the standout features across these models is their energy efficiency. Equipped with high SEER (Seasonal Energy Efficiency Ratio) ratings, they help users save on energy costs while reducing their carbon footprint. Specifically, the SS14N10* and SS12N10* models excel in cooling efficiency, ensuring that the spaces they occupy remain comfortably cool even in the hottest conditions. This not only contributes to lower energy bills but also promotes environmental sustainability.

The cooling technologies integrated into these units include advanced inverter technology. This feature allows the compressor to adjust its speed according to the cooling demand of a room. As a result, these air conditioners maintain desired temperatures with minimal fluctuations, ensuring optimal comfort and significant energy savings. Models like SS15N30* and SM18N30* are particularly stellar in maintaining efficiency even during peak usage hours.

Moreover, these air conditioners are equipped with multi-stage filtration systems that enhance indoor air quality. The filters effectively capture dust, allergens, and other pollutants, resulting in cleaner and healthier air for occupants. This is especially important for individuals with allergies or respiratory issues.

User-friendly controls add another layer of convenience. Many models incorporate smart technology allowing users to control the units via mobile apps or home automation systems. This feature enables remote operation, scheduling, and real-time monitoring, making it easier to manage climate conditions effectively.

In terms of design, models like SS10N10* prioritize aesthetics without compromising functionality. They feature sleek, modern designs that seamlessly integrate into various decors, whether in a home or an office. Additionally, quiet operation technology reduces noise levels during functionality, enhancing comfort, particularly in bedrooms or quiet office environments.

Overall, Friedrich’s SS14N10*, SS12N10*, SS15N30*, SS10N10*, and SM18N30* models embody the brand's commitment to innovation and customer satisfaction. Their blend of energy efficiency, advanced cooling technology, air quality enhancement, and smart controls positions them as leaders in the air conditioning market, catering to diverse cooling needs while promoting a sustainable future.
