thermostat wire. 

4.  When thermostat satisfied, connection 

between red and yellow broken at

Refer to Ladder Diagram and Wiring 
Schematic for relay locations. 
 Note: 

MaxAir

™ air handlers are equipped 

with a brushless dc fan motor. Speeds for 
heating, cooling and continuous run are all 
field selectable. Refer to

Heating Cycle 

1.   Thermostat calls for heat, connection 

is made between the (“R” terminal) red 
and (“W1” and or “W2” terminal) 
thermostat wires as set up by installer. 

2  Heating relay is energized; providing 

power to relay A1, circulating pump 
connection point.  After “15 second 
delay” to allow plenum to warm up, 
Fan motor starts at value selected by 
installer and corresponding W1 or W2 
input. If 2-stage timed heat is selected 
at control board, fan speed will not 

increase to the “W2” value until after a 
programmed 5 minute delay 

3  If R + D (optional aquastat circuit) are 

interrupted, motor remains at 
continuous low input value until circuit 
is made.  

4  When room temperature is satisfied, 

thermostat breaks connection 
between “R” and “W1” / “W2” wires. 

5  Relays are de-energized; pump stops, 

fan shuts off (or switches to 
continuous run speed when 
continuous run employed). 

 

Cooling Cycle 

Thermostat calls for cooling, 

connection is made between (“R” 
terminal) red (“G” terminal) green and 
(“Y1”or “Y2” terminal, factory bridged) 
thermostat wires, as selected by the 
installer.
