General Information

(option) Boilerless Control/Electric

Heat

Systems that do not contain a boiler may contain a boilerless control with electric heat. Trane offers both a facto- ry mounted electric heat option, and a field mounted duct heater option.

If the 1/2 through 5 ton GEH and GEV unit incorporates the factory mounted option, the unit will ship from the fac- tory with an internally mounted nichrome open wire heating element, designed to start-up electric heat as the systems primary heat in the event entering water temperature falls be- low 55 F. Once the entering water tem- perature rises above 60 F, the boilerless controller returns the unit to normal compressor heating operation, and locks out the electric heater.

If the unit contains a cooling only heat pump design, the electric heat contac- tor is wired directly to the thermostat for primary heating, and the compres- sor contactor for cooling.

For units comprised of the field in- stalled duct heater option, the unit will ship from the factory with controls available to interface with the field provided electric heat selection.

Note: For geothermal applications, the boilerless controller has an adjustable setting of 25, 35, 45, 55 and 60 de- grees.

(option) Supplemental or

Boilerless Electric Heat

The 6 through 25 ton models which contain boilerless control electric heat or supplemental electric heat will con- tain the controls interface ONLY for field provided electric heat selection. The heater for this model shall be ex- ternal to the equipment by the contrac- tor for ease of installation. All power connections for the electric heater will be completely separate from the unit for field supplied electric heat.

Note: When the unit has boilerless control, the electric heat is not used as supplemental electric heat, but as a primary heat.

(option) Hot Gas Reheat

With the reheat option, the return-air from the space is conditioned by the air-to-refrigerant coil, then reheated by the reheat coil to control not only the space temperature, but to also re- duce the relative humidity of the space. When operating in the reheat mode (meaning the sensible tempera- ture has been met in the space), the humidistat signals the reheat relay coil to energize, allowing the high pres- sure refrigerant gas to flow from the compressor through the reheat valve, into the reversing valve, or reheat coil for dehumidification.

A switching relay has been provided for the reheat application to adjust the blower motor from normal operation to low speed when the hot gas reheat is energized (for 1/2 through 5 ton equipment only).

Notes:

A high static blower motor is re- quired to support the hot gas re- heat option for the 1/2 through 5 ton equipment.

Units containing the hot gas reheat option should not be used as a make-up air unit.

Water regulating valves should not be used with the hot gas reheat op- tion. Trane places a thermal expan- sion valve on all WSHPs as well as GSHPs to regulate refrigerant flow vs. water flow to the unit.

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.
