NOTE - Units equipped a Variable Frequency Drive (VFD) are designed to operate on balanced, three-phase power. Operating units on unbalanced three-phase power will reduce the reliability of all electrical components in the unit. Unbalanced power is a result of the power delivery system supplied by the local utility company. Factory-installed inverters are sized to drive blower motors with an equivalent current rating using balanced threephase power. If unbalanced three-phase power is supplied, the installer must replace the existing factory-installed inverter with an inverter that has a higher current rating to allow for the imbalance. Refer to the installation instructions for additional information and replacement information.

Objective: Outline the unit functions as a result of room thermostat or zone sensor demands. Given: When economizer is present, it will function as an integral part of the unit cooling system. When not present, unit will function as if economizer is present but outdoor ambient is high and sensed as not suitable. UNIT OPERATION WITH 2-STAGE THERMOSTAT (2 COOL AND 2 HEAT STAGES, Y1, Y2, W1, W2) Supply Air Blower Speed
Unit has following supply air blower speed setting:  Ventilation speed  Cooling Speed - Low  Cooling Speed - High  Heating speed  Smoke speed (Used only in smoke removal option - not discussed)
¹ Unit Features An Economizer And Outdoor Air Is Suitable
Cooling - Thermostat Mode (Y1, Y2) Y1 Demand: All compressors are off, supply air blower is on low cooling speed to minimize blower power consumption, economizer modulates (minimum to maximum open position) to maintain 55°F supply air temperature (default unit controller setting). Y2 Demand: All compressors are off, supply air blower is on high cooling speed providing higher cooling capacity, and economizer modulates to maintain 55°F supply air temperature. If economizer stays at maximum open for 3 minutes, compressor 1 is energized while supply air blower stays on high cooling speed providing maximum cooling capacity.
¹ O utdoor air suitability is determined by the energy state of outdoor ambient (enthalpy or sensible) and its ability to achieve the desired free cooling effects. Outdoor air suitability can also be determined by a third party controller and provided to the rooftop unit via a network connection.
Unit Does Not Feature An Economizer Or Outdoor Air Is Not Suitable
Y1 Demand: Compressor 1 operates, and supply air blower operates at low cooling speed. Y2 Demand: All compressors operate and supply air blower operates at high cooling speed.

Unit has following supply air blower speed setting:  Ventilation speed  Cooling Speed - Low  Cooling Speed - Medium  Cooling Speed - High  Heating speed  Smoke speed (Used only in smoke removal option - not discussed)
¹ Unit Features An Economizer And Outdoor Air Is Suitable
Cooling - Thermostat or Zone Sensor Mode (Y1, Y2, Y3) Y1 Demand: All compressors are off, supply air blower is on low cooling speed to minimize blower power consumption, economizer modulates (minimum to maximum open position) to maintain 55°F supply air temperature (default unit controller setting). Y2 Demand: All compressors are off, supply air blower is on high cooling speed providing higher cooling capacity, and economizer modulates to maintain 55°F supply air temperature. If economizer stays at maximum open for 3 minutes, compressor 1 is energized while supply air blower stays on high cooling speed providing maximum cooling capacity. After compressors are energized the economizer stays at maximum open. Y3 Demand: Compressors 1 and 2 are energized while supply air blower stays on high cooling speed.
¹ O utdoor air suitability is determined by the energy state of outdoor ambient (enthalpy or sensible) and its ability to achieve the desired free cooling effects. Outdoor air suitability can also be determined by a third party controller and provided to the rooftop unit via a network connection.
Unit Does Not Feature An Economizer or Outdoor Air Is Not Suitable
Y1 Demand: Compressor 1 operates at part load and supply air blower operates at low cooling speed. Y2 Demand: Compressor 1 operates at part load with compressor 2 ON, and supply air blower operates at medium cooling speed. Y3 Demand: All compressors operate and supply air blower operates at high cooling speed. Defrost Mode
Coil Sensors (RT48 - Circuit 1 and RT49 - Circuit 2) and Ambient Sensor (RT17) provides input to the Lennox® CORE Unit Controller to initiate a defrost cycle if needed. Coil sensors are located on a return bend for each circuit on the front of the outdoor coil. Ambient sensor is located on the inside of the corner mullion on the back of the outdoor coil section. If a coil sensor measures a temperature below 35°F during mechanical heating mode, defrost logic is enabled. The system will constantly monitor coil and ambient temperatures and will initiate a defrost cycle if the controller determines that the target temperature difference between the coil and ambient temperature has been satisfied, or when the accumulated run time with coil temperature below 35°F reaches 6 hours. Defrost will not be activated on more than one circuit at the time. If the ambient sensor fails, or the circuit is in uncalibrated state, the controller will switch to time/temperature defrost operation. Electric heat is energized during a defrost cycle to maintain discharge air temperature.

Heating Mode: Thermostat or Zone Sensor W1 Demand: A first-stage heating demand (W1) will energize compressors 1 and 2 and the outdoor fans.
NOTE ­ L1 & L2 reversing valves are de-energized in the heating mode. Units With Optional Electric Heat: An increased heating demand (W2) will energize electric heat. Electric heat is also energized during the defrost cycle (W1) to maintain discharge air temperature.
Modulating Outdoor Air Damper
The minimum damper position for "occupied low blower" and "occupied high blower" is adjusted during unit setup to provide minimum fresh air requirements per ASHRAE 62.1 at the corresponding supply air blower speeds.
 When supply air blower is off or the unit is in unoccupied mode, the outdoor air damper is closed.  When unit is in occupied mode and supply air blower is operating at a speed below the "midpoint" blower
speed, the outdoor air damper is at minimum "low blower" position.  When unit is in occupied mode and supply air blower is operating at a speed equal to or above the
"midpoint" blower speed, the outdoor air damper is at minimum "high blower" position. NOTE - The "midpoint" blower speed is an average of the minimum and maximum blower speed (minimum speed +
maximum speed divided by 2). Power Exhaust Operation
NOTE - POWER EXHAUST OPERATION IS THE SAME FOR ALL CONTROL OPTIONS MSAV® models are equipped with 2-stage power exhaust fans. Power exhaust fans operate when economizer outdoor air dampers are 50% open (adjustable). Power exhaust operates in 1st stage (one fan) up to 70% of supply air blower speed. 2nd stage power exhaust fans (both fans) operate when supply air blower speed is above 70% (adjustable) of full speed.
