Vl. ELECTRICAL OPERATION

COOUNG CYCLE

With the disconnect on "ON" position, voltage is supplied to the primary of the control transformer and crankcase heater. The control transformer reduces the voltage from 230 or 208 to 24 volts for the low

voltage and the thermostat circuit. With a single-stage cool/single-stage heat t_Lh_mostat set in the cooling _o_ition, current is supplied from one side of the 24 volt secondary of the control transformer to the "R" terminal of the thermostat. The other side of this transformer connects to the main contractor

coil through the high pressure control. When the thermostat calls for"COOLING', current from the "R" terminal is switched on to the =Y" terminal causing the compressor contactor to be energized. The main contactor closes the contacts in the high voltage circuit. The completion of this circuit will start both the outdoor fan motor and the compressor.

The indoor fan relay which is internally wired from "G" to "Y" in the thermostat sub-base is also energized and starts the indoor fan motor. The system will operate normally and begin to cool.

HEATING CYCLE

With the thermostat set in the heating mode, the "B" terminal energizes the reversing valve relay. With a call for heat the compressor contactor is energized "W" to =Y"through the jumper wire in the control panel. The indoor and outdoor fan motors are started in the same manner as in the cooling cycle. The reversing valve is always energized whenever the system switch on the thermostat is in the heat position. This eliminates the =swish" at the end of each cycle. Only in the de-ice cycle will the "swish"

occur.

VII. RESISTANCE HEATERS

Resistance heaters are available as an optional field-installed accessory for self-contained heat pumps. Resistance heaters are recommended for areas where winters are severe, because as the outdoor temperature falls, the amount of heat available in the air decreases, making it more difficult to capture. This fact of nature causes the heat pump capacity to fall at a time when the heating requirement rises. Resistance heaters can compensate for this difference in capacity.

Heat pumps with resistance heaters require a single-stage cool/two-stage heat thermostat. With the two-stage thermostat, the resistance heaters are energized if the thermostat is turned more than two degrees higher than the indoor temperature, or the indoor temperature falls more than two degrees below the thermostat setting. The heaters will also be energized during the defrost cycle.

Heat Pump specifications

Goetti Air Conditioning Heat Pump systems represent a significant advancement in climate control technology, offering efficient heating and cooling solutions for residential and commercial properties. These innovative systems are designed to provide year-round comfort while maximizing energy efficiency and minimizing environmental impact.

One of the main features of Goetti heat pumps is their advanced inverter technology. This system allows for variable speed operation, meaning the pump can adjust its output to match the heating or cooling needs of a space more precisely. This results in significant energy savings, as the system can operate at lower speeds most of the time, consuming less power while maintaining a constant temperature.

Moreover, Goetti heat pumps utilize eco-friendly refrigerants that adhere to the latest environmental regulations. This commitment to sustainability not only helps reduce the carbon footprint of the system but also ensures that users are compliant with existing and future environmental standards. The use of these refrigerants contributes to the overall efficiency of the unit, as they improve heat transfer and reduce energy consumption.

Another characteristic of Goetti heat pumps is their exceptional durability and reliability. Constructed from high-quality materials, these systems are designed to withstand various weather conditions, ensuring optimal performance even in extreme temperatures. The robust design not only extends the lifespan of the heat pump but also reduces maintenance costs, as fewer repairs are needed over time.

Goetti offers heat pumps in a range of sizes and capacities, making it easy for consumers to find the perfect fit for their specific needs. Additionally, many models come equipped with smart technology, allowing for remote operation and monitoring through mobile applications. This feature enables users to optimize their energy usage, set schedules, and ensure that their comfort needs are always met, regardless of their location.

The noise level of Goetti heat pumps is also commendable. With advanced noise reduction technologies, these systems operate quietly, ensuring a peaceful indoor environment. This aspect is particularly beneficial for residential applications, where noise can be a significant concern.

In summary, Goetti Air Conditioning Heat Pump systems are a testament to innovation in climate control technology. With their advanced inverter technology, eco-friendly refrigerants, robust construction, and smart features, they offer a reliable and efficient solution for heating and cooling needs. Emphasizing sustainability, performance, and user convenience, Goetti continues to lead the way in creating comfortable living and working environments.
