aIf Installer Setup (0170) System Type is set to 2 pipe Fan Coil (8) or 2 pipe Fan Coil w/Aux Heat (9), the Y terminal will be used
for cooling and heating. If Installer Setup (0170) System Type is set to 4 pipe Fan Coil (7), the Y terminal will be used for cooling
only.
bWhen fan is in AUTO, it automatically selects the fan speed based on how far away the temperature is from the setpoint.
cIf Installer Setup (0170) System Type is set to 2 pipe Fan Coil with Auxiliary Heat (9), the W1 terminal will be used for reheat. If
Installer Setup (0170) System Type is set to 4 pipe Fan Coil (7),the W1 terminal will be used for heating.
aWhen the fan is in AUTO, it automatically selects the fan speed based on how far away the temperature is from the setpoint.
bConfigure O/B in Installer Setup. Based on last piece of equipment called (cooling=O; heating=B).
cIf Installer Setup (1070) System Type is set to 2Heat/1 Cool PTAC.
