ELECTRONIC CONTROL BOARD FEATURES

The new Friedrich Vert-I-Pak has state of the art features to improve guest comfort and conserve energy. Through the use of specifi cally designed control software, Friedrich has accomplished what other Manufacturer’s have only attempted – a quiet, dependable, affordable and easy to use Vert-I-Pak.

Below is a list of standard features on every Friedrich VPAK and their benefi t to the owner.

Quiet Start/Stop

The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing

or stopping immediately. Upon call for cooling or heating the unit fan will run for fi ve seconds prior to en-

Fan Delay

ergizing the compressor. Also, the fan off delay allows for “free cooling” by utilizing the already cool indoor

 

coil to its maximum capacity by running for 30 seconds after the compressor.

 

 

Remote Thermostat

VPAK units are controlled by a wired remote wall thermostat.

Operation

 

 

 

Internal Diagnostic

The new Friedrich digital VPAK features a self diagnostic program that can alert maintenance to compo-

nent failures or operating problems. The internal diagnostic program saves properties valuable time when

diagnosing running problems.

 

 

 

Service Error Code

The self diagnosis program will also store error codes in memory if certain conditions occur and correct

themselves such as extreme high or low operating conditions or activation of the room freeze protection

Storage

feature. Storing error codes can help properties determine if the unit faced obscure conditions or if an error

 

occurred and corrected itself.

 

 

Random

Multiple compressors starting at once can often cause electrical overloads and premature unit failure.

The random restart delay eliminates multiple units from starting at once following a power outage or initial

Compressor Restart

power up. The compressor delay will range from 180 to 240 seconds.

 

 

 

Heat Pump Units

The new Friedrich VPAK uses a digital thermostat to accurately monitor the outdoor coil conditions to allow

 

Digital Defrost

the heat pump to run whenever conditions are correct. Running the VPAK in heat pump mode save energy

Thermostat

and reduces operating costs. The digital thermostat allows maximization of heat pump run time.

 

 

 

Instant Heat

Heat pump models will automatically run the electric heater during compressor lock-out to quickly provide

heat when initially energized, then return to heat pump mode. This ensures that the room is heated quickly

without the usual delay associated with heat pump units.

 

 

 

 

The room air sampling feature maintains a balanced temperature throughout the room by circulating the

Room Air

air for 90 seconds once every 9 minutes that the unit is not running when it is set to cooling or heating

mode. By circulating the air, the unit can detect hot or cold areas in the room and operate the unit to cool

or warm the room as necessary. This function is only available when the fan mode is set to ‘AUTO’ during

 

 

COOL or HEAT Mode.

 

 

 

All electronic VPAK units have low voltage terminals ready to connect a desk control energy management

Desk Control Ready

system. Controlling the unit’s on/off operation from a remote location like the front desk can reduce energy

 

usage and requires no additional accessories at the VPAK.

 

 

Indoor Coil Frost

The frost sensor protects the compressor from damage in the event that airfl ow is reduced or low outdoor

temperatures cause the indoor coil to freeze. When the indoor coil reaches 30°F the compressor is

Sensor

diabled and the fan continues to operate based on demand. Once the coil temperature returns to 45°F the

 

compressor returns to operation.

 

 

Auxiliary Fan Ready

The VPAK features a 24V AC terminal for connection to a relay that may be used to operate an auxiliary

fan to transfer air to adjoining rooms. Auxiliary fans can provide air conditioning to odd shaped rooms.

R410A specifications

Friedrich R410A is a refrigerant blend that has become a cornerstone in the HVAC industry, particularly for air conditioning systems. This hydrofluorocarbon (HFC) is known for its efficiency and environmentally friendly properties, making it a popular alternative to older refrigerants like R22.

One of the main features of R410A is its exceptional thermal efficiency. It has a higher cooling capacity compared to R22, which allows for smaller and more efficient equipment. This efficiency translates to reduced energy consumption and lower operating costs for users. Additionally, the higher pressure capability of R410A enables the design of more compact systems, which is particularly beneficial for residential and commercial applications where space is often limited.

R410A is characterized by its zero ozone depletion potential (ODP), which is a significant advantage over its predecessors. This makes it a more environmentally responsible choice, aligning with global initiatives to phase out substances that harm the ozone layer. However, it is essential to note that while R410A does not deplete the ozone, it does have a global warming potential (GWP) of approximately 2,088, making it less favorable in terms of climate impact compared to natural refrigerants.

In terms of technology, R410A is typically utilized in systems that are designed specifically for this refrigerant. Equipment compatible with R410A often features advanced components that can handle the higher pressures required. Many modern air conditioning systems equipped with R410A also incorporate variable-speed compressors and advanced electronic controls, enhancing overall performance and comfort.

Additionally, R410A systems often come equipped with variable refrigerant flow (VRF) technology, which allows for precise temperature control in multiple zones of a building. This versatility makes R410A an ideal choice for both residential and commercial installations, providing optimal comfort throughout various spaces.

In summary, Friedrich R410A stands out due to its high energy efficiency, zero ozone depletion potential, and suitability for modern HVAC technologies. As the industry moves towards more sustainable practices, R410A serves as a reliable refrigerant that balances performance with environmental responsibility. It’s a significant choice for anyone looking to invest in efficient and eco-friendly heating and cooling solutions.
