ELECTRICAL - POWER WIRING

Power Connection

Line voltage connection is made by connecting the incoming line voltage wires to the “L” side of the contactor as shown in Figures 18. Consult Table 4 for correct fuse size.

208 Volt Operation

All residential 208-230 Volt units are factory wired for 230 Volt operation. The transformer may be switched to the 208V tap as illustrated on the wiring diagram by switching the red (208V) and the orange (230V) wires at

Blower Speed Selection

PSC (Permanent Split Capacitor) blower fan speed can be changed by moving the blue wire on the fan motor terminal block to the desired speed as shown in Figure

19.Units are shipped on the medium speed tap. Consult engineering design guide for specific unit airflow tables. Typical unit design delivers rated airflow at nominal static (0.15 in. w.g. [37Pa]) on medium speed and rated airflow at a higher static (0.4 to 0.5 in. w.g. [100 to 125 Pa]) on high speed for applications where higher static is required. Low speed will deliver approximately 85% of rated airflow at 0.10 in. w.g. [25 Pa].

Fieldld Wiring

Special Note forAHRITesting: To achieve rated airflow for AHRI testing purposes on all PSC products, it is necessary to change the fan speed to “HI” speed. When the heat pump has experienced less than 100 operational hours and the coil has not had sufficient time to be “seasoned”, it is necessary to clean the coil with a

HWG Wiring

The hot water generator pump power wiring is disabled at the factory to prevent operating the HWG pump “dry.” After all HWG piping is completed and air purged from the water piping, the pump power wires should be applied to terminals on the HWG power block PB2 as shown in the unit wiring diagram. This connection can also serve as a HWG disable when servicing the unit.

HEV/H specifications

The Heat Controller HEV/H series represents a significant advancement in heating technology, designed to provide efficient and effective climate control for both residential and commercial spaces. This innovative range of heat pumps combines cutting-edge features with user-friendly functionality to offer a reliable solution for modern heating needs.

One of the standout features of the HEV/H series is its advanced inverter technology. This system allows the heat pump to adjust its output based on the specific heating requirements of the environment. By varying the compressor's speed, the HEV/H maintains a consistent temperature while significantly reducing energy consumption. This not only lowers utility bills but also reduces environmental impact, making it a more sustainable option compared to traditional heating methods.

The HEV/H series is equipped with a high-efficiency heat exchanger, which maximizes heat transfer and enhances overall performance. This component ensures that the system can operate effectively even in colder climates, providing reliable heating throughout the winter months. Additionally, the unit’s low noise operation is designed to maintain a peaceful environment, making it suitable for bedrooms, offices, and other noise-sensitive areas.

Another notable characteristic of the HEV/H series is its smart control features. Integrated with Wi-Fi connectivity, users can conveniently manage their heating settings remotely via a smartphone app. This feature allows for customized scheduling and temperature control, ensuring optimal comfort and convenience. Users can also receive real-time notifications on energy consumption and system performance, enhancing user engagement and control.

The HEV/H series also emphasizes durability and longevity. Constructed with high-quality materials, the units are designed to withstand the rigors of daily use while requiring minimal maintenance. The incorporation of advanced filtration systems helps to improve indoor air quality by capturing dust and allergens, which is especially beneficial for individuals with allergies or respiratory issues.

In summary, the Heat Controller HEV/H series exemplifies modern heating technology with its combination of efficiency, control, and user-friendly features. Its inverter technology, high-efficiency heat exchangers, smart connectivity, and durable construction make it an outstanding choice for anyone seeking to enhance their indoor climate while being conscious of energy usage and environmental impact. Whether for a home or business, the HEV/H series is poised to deliver exceptional heating solutions tailored to diverse needs.
