PRODUCT DESIGN This section gives a basic description of cooling unit operation, its various components and their basic operation. Ensure your system is properly sized for heat gain and loss according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent. CONDENSING UNIT The condenser air is pulled through the condenser coil by a direct drive propeller fan. This condenser air is then discharged out of the top of the cabinet.
PRODUCT DESIGN The ASX & ASXC [16 & 18], ASZ & ASZC [16 & 18], DSX & DSXC [16 & 18] and DSZ & DSZC [16 & 18] series split system units use a two-stage scroll compressor. The twostep modulator has an internal unloading mechanism that opens a bypass port in the first compression pocket, effectively reducing the displacement of the scroll. The opening and closing of the bypass port is controlled by an internal electrically operated solenoid.
PRODUCT DESIGN CAPACITY CONTROL - LEGACY MODELS During the compression process, there are several pockets within the scroll that are compressing gas. Modulation is achieved by venting a portion of the gas in the first suction pocket back to the low side of the compressor thereby reducing the effective displacement of the compressor. See Figure A. Full capacity is achieved by blocking these vents, increasing the displacement to 100%.
SYSTEM OPERATION COOLING The refrigerant used in the system is R-410A. It is a clear, colorless, non-toxic and non-irritating liquid. R-410A is a 50:50 blend of R-32 and R-125. The boiling point at atmospheric pressure is -62.9°F. The check valve at the indoor coil will open by the flow of refrigerant letting the now condensed liquid refrigerant bypass the indoor expansion device.
SYSTEM OPERATION When the thermostat is satisfied, appropriate commands are sent to the UC control. The compressor relay and outdoor fan relay is de-energized. The compressor high stage solenoid is de-energized if it was energized. The UC control sends an appropriate command to the indoor unit to deenergize the indoor blower motor. If room thermostat fan status is set to be “on”, then indoor blower would run continuously rather than cycling with the compressor.

SYSTEM OPERATION EXPANSION VALVE/CHECK VALVE ASSEMBLY IN COOLING OPERATION EXPANSION VALVE/CHECK VALVE ASSEMBLY IN HEATING OPERATION Most expansion valves used in current Amana® Brand Heat Pump products use an internally checked expansion valve. This type of expansion valve does not require an external check valve as shown above. However, the principle of operation is the same.

SERVICING SEQUENCE OF OPERATION MBR/AR*F WITH SINGLE STAGE HEAT PUMPS This document covers the basic sequence of operation for a typical application with a mercury bulb thermostat. When a digital/electronic thermostat is used, the on/off staging of the auxiliary heat will vary. Refer to the installation instructions and wiring diagrams provided with the MBR/AR*F for specific wiring connections and system configuration. 3.0 Cooling Operation MBR/AR*F WITH SINGLE STAGE CONDENSERS 1.0 Cooling Operation 1.
SERVICING the “W3” demand is satisfied, the room thermostat will remove the 24Vac from HR2. The contacts on HR2 will open between 30 to 70 seconds and heater elements #3 and #4 will be turned off. On most digital/electronic thermostats, “W3” will remain energized until the first stage heat demand “Y” is satisfied and then the “G”, “Y”, “W2” and “W3” demands will be removed. 5.
SERVICING if the heater assembly contains a second heater element, HR1 will contain a second set of contacts, M3 and M4, which will close and turn on heater element #2. Note: If more than two heater elements are on the heater assembly, it will contain a second heat sequencer, HR2, which will control the 3rd and 4th heater elements if available. For the 3rd and 4th heater elements to operate on a second stage heat demand, the PJ4 jumper on the VSTB inside the MBE/AEPF must be cut.
SERVICING 4.4 As the temperature indoors increase, it will reach a point where the second stage heat demand, “W2”, is satisfied. When this happens, the room thermostat will remove the 24Vac from “E/W1” of the MBE/AEPF. The contacts on HR1 will open between 30 to 70 seconds and turn off both heater element(s). The heat pump remains on along with the blower motor because the “Y” demand for first stage heat will still be present. 4.
SERVICING “Y1”. The MBE/AEPF removes the 24Vac from “Ylow/ Y1’ at the condenser and the compressor and condenser fan are turned off. The blower motor will ramp down to a complete stop based on the time and rate programmed in the motor. 2.0 Heating Operation 2.1 On a demand for heat, the room thermostat energizes “W1” and 24Vac is supplied to terminal “E/W1” of the VSTB inside the MBE/AEPF unit.
SERVICING VSTB will turn on the blower motor and the motor will ramp up to 60% of the speed programmed in the motor based on the settings of dip switch 1 and 2. The VSTB will supply 24Vac to “Y” at the heat pump. The compressor will start on low stage and outdoor fan will start on low speed on a “Y1” heating demand but the blower motor will deliver only 60% of the programmed cfm for high speed heating operation. 4.
SERVICING 5.6 When the defrost cycle is terminated, the contacts of the HVDR relay on the defrost board will close to start the outdoor fan and the contacts of the LVDR relay will open and turn off the reversing valve and electric heater(s). The unit will now be back in a normal heating mode with a heat pump demand for heating as described in the Heating Operation in section 4. See section 5.4a. SEQUENCE OF OPERATION AVPTC/MBVC with Single Stage Condensers (24VAC Legacy Wired Systems) 1.
SERVICING at the integrated AH control. Thermostat "G" and "Y" contacts remain closed. 2.5 Upon receiving a demand for auxiliary heat, the control determines the appropriate airflow demand for heat pump + auxiliary heat operation and operates the ECM blower motor at that airflow demand. The control determines which airflow demand is greatest and applies that demand when operating the ECM blower motor. 2.6 The system operates at single stage heat pump heating plus auxiliary heat. 2.
SERVICING 2.5 Upon receiving the high stage auxiliary heat demand, the control operates the ECM blower motor at the high stage auxiliary heat airflow. 2.6 Upon satisfying the thermostat, the "W1" thermostat contacts (or "W1" and "W2" contacts) open, removing 24VAC from the integrated air handler control and outdoor unit. The compressor and condensor fan motor are immediately de-enerized.
SERVICING 3.2 Removing the thermostat demand for continuous fan opens the "G" contacts, removing 24VAC from the integrated air handler control. The integrated AH control immediately de-energizes the ECM blower motor. 4.0 Defrost Operation 4.1 The control in the outdoor unit determines when a defrost cycle is needed. Upon determing that a defrost cycle is needed, the outdoor control de-energizes the condensor fan motor and energizes the reversing valve.
SERVICING AVPTC/MBVC with ASZC/DSZC Heat Pump and CTK0* Communicating Themostat The AVPTC or MBVC air handle/modular blower matched with an ASZC or DSZC condensing unit and CTK0* communicating thermostat constitute a network. The three components, or subsystems, making up the system communicate with one another with information passed between all three components. This leads to a somewhat non-traditional manner in which the system components receive commands for system operation.
SERVICING The air handler/modular blower is commanded to end auxiliary heat operation. The air handler control deenergizes the electric heat sequencer outputs. The ECM blower motor remains energized until any blower OFF delay timing has expired. Outdoor Temperature Below the Heat Pump Balance Point 2.1 The CTK0*** thermostat sends a request for the outdoor air temperature to the heat pump. The heat pump returns an outdoor air temperature that is below the balance point temperature.
SERVICING NOTE: The temperature rise table is for sea level installations. The temperature rise at a particular KW and CFM will be greater at high altitudes, while the external static pressure at a particular CFM will be less. HIGH VOLTAGE! Disconnect ALL power before servicing or installing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. CFM 1. Disassemble and remove the heating element(s). 2.
