UNIT START-UP PROCEDURE

UNIT START-UP PROCEDURE

Note: Units have a five minute time delay in the control circuit that can be eliminated on the CXM control board as shown below in Figure 30. See controls description for details.

c.Verify that the compressor is on and that the water flow rate is correct by measuring pressure drop

through the heat exchanger using the P/T plugs and comparing to Table10C.

d.Check the elevation and cleanliness of the condensate lines. Dripping may be a sign of a blocked line. Check that the condensate trap is filled to provide a water seal.

e.Refer to Table 9. Check the temperature of both entering and leaving water. If temperature is within range, proceed with the test. If temperature is outside of the operating range, check refrigerant

pressures and compare to Tables 10 through

12. Verify correct water flow by comparing unit

pressure drop across the heat exchanger versus the data in Table10C. Heat of rejection (HR) can be

calculated and compared to catalog data capacity pages. The formula for HR for systems with water is as follows:

HR = TD x GPM x 500, where TD is the temperature difference between the entering and leaving water, and GPM is the flow rate in U.S. GPM, determined by comparing the pressure drop across the heat exchanger to Table 10C.

f.Check air temperature drop across the air coil when compressor is operating. Air temperature drop should be between 15°F and 25°F [8°C and 14°C].

g.Turn thermostat to “OFF” position. A hissing noise indicates proper functioning of the reversing valve.

6.Allow five (5) minutes between tests for pressure to equalize before beginning heating test.

a.Adjust the thermostat to the lowest setting. Place the thermostat mode switch in the “HEAT” position.

b.Slowly raise the thermostat to a higher temperature until the compressor activates.

c.Check for warm air delivery within a few minutes after the unit has begun to operate.

d.Refer to Table 9. Check the temperature of both entering and leaving water. If temperature is within range, proceed with the test. If temperature is

outside of the operating range, check refrigerant pressures and compare to Table 13. Verify correct water flow by comparing unit

pressure drop across the heat exchanger versus the data in Table 10C. Heat of extraction (HE) can be calculated and compared to submittal data capacity pages. The formula for HE for systems with water is as follows:

HE = TD x GPM x 500, where TD is the temperature difference between the entering and leaving water, and GPM is the flow rate in U.S. GPM, determined by comparing the pressure drop across the heat exchanger to Table 8.

e.Check air temperature rise across the air coil when

compressor is operating. Air temperature rise should be between 20°F and 30°F [11°C and 17°C].

f.Check for vibration, noise, and water leaks.

7.If unit fails to operate, perform troubleshooting analysis (see troubleshooting section). If the check described fails to reveal the problem and the unit still does not operate, contact a trained service technician to insure proper diagnosis and repair of the equipment.

8.When testing is complete, set system to maintain desired comfort level.

9.BE CERTAIN TO FILL OUT AND FORWARD ALL WARRANTY REGISTRATION PAPERS TO HEAT CONTROLLER.

Note: If performance during any mode appears abnormal, refer to the CXM section or troubleshooting section of this manual. To obtain maximum performance, the air coil should be cleaned before start-up. A 10% solution of dishwasher detergent and water is recommended.

ѥ WARNING! ѥ

WARNING! When the disconnect switch is closed, high voltage is present in some areas of the electrical panel. Exercise caution when working with energized equipment.

ѥ CAUTION! ѥ

CAUTION! Verify that ALL water control valves are open and allow water flow prior to engaging the compressor. Freezing of the coax or water lines can permanently damage the heat pump.

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.
