Initial Unit Start-up

Note: Start-up for the Terminal Unit Controller (TUC) may be found in WSHP-IOP-1. Start-up for the Tracer ZN510 controller may be found in WSHP-IOP-2. Start-up for the Tracer ZN524 controller may be found in WSHP-PRB002-EN.

Start-up with the conventional thermostat is included below:

1.Set the thermostat to the highest position.

2.Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.

3.Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized. Adjust water flow utilizing pressure/temperature plugs and comparing to tables contained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9-12ºF); blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction line should be cool with no frost observed in the refrigerant circuit.

4.Check the cooling refrigerant pressures against values in Table 7. (Page 75).

5.Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de- energize.

6.Leave unit off for approximately FIVE minutes to allow for pressure equalization.

7.Turn the thermostat to the lowest setting.

8.Set the thermostat system switch to the HEAT position.

9.Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water temperature decrease of approximately 5-9ºF leaving the heat exchanger should be noted. The blower and compressor operation should be smooth with no frost observed in the refrigeration circuit.

10.Check the heating refrigerant pressures against values in Table 7. (Page 75)

11.Set the thermostat to maintain the desired space temperature.

12.Instruct the owner on system operation.

GEV, GEH specifications

Trane has long been a leader in the HVAC industry, and their GEH and GEV series of heat pumps are a testament to their commitment to innovation and efficiency. These models are designed to provide substantial energy savings while maintaining exceptional performance, making them ideal choices for both residential and commercial applications.

The Trane GEH and GEV heat pumps feature advanced variable-speed technology, which allows them to adjust their output to match the current heating or cooling demand. This adaptability not only enhances comfort by maintaining a consistent indoor temperature but also leads to significant energy savings by reducing unnecessary energy consumption during partial-load conditions. By running more efficiently at lower speeds, these units reduce wear and tear on components, extending the lifespan of the system.

One of the defining characteristics of the GEH and GEV models is their high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. These ratings demonstrate the units' ability to provide efficient heating and cooling throughout the year, contributing to lower energy bills. The use of R-410A refrigerant is another key feature, as it is both environmentally friendly and efficient, ensuring that these systems meet stringent regulatory standards while delivering reliable performance.

Installation flexibility is another highlight of the Trane GEH and GEV series. These units are designed to work seamlessly with existing HVAC systems, making retrofitting straightforward. Their compact design allows for easy placement, even in tight spaces, without compromising performance. Additionally, Trane's commitment to quality is evident in the construction of these heat pumps, as they are built to withstand harsh weather conditions and provide reliable service year after year.

Moreover, both the GEH and GEV models are equipped with integrated smart controls that simplify operation and maintenance. These controls allow homeowners and facility managers to monitor energy usage, adjusting settings remotely and scheduling maintenance checks to maximize efficiency. This technology not only enhances user experience but also promotes energy conservation through intelligent management.

In summary, Trane's GEH and GEV heat pumps stand out for their variable-speed technology, high efficiency ratings, installation flexibility, and smart controls. These features make them an ideal solution for those seeking a reliable, energy-efficient heating and cooling option, reflecting Trane's dedication to performance and sustainability.
