Quick System Setting Reference
H1 Emergency Disconnect:
(Remove pin to activate)
H2 Timer:
Activates auxiliary relay for 5 min
every 24 hours.
H3 Mode (Auto):
Blower output speed modulates
dependent upon static pressure.
H3 Mode (Manual):
Blower output speed operates at fixed
flow rate.
H4 Delay:
Cooling/20second, heating/30 second
fan delay, and 30 second post purge.
Note: If trim pots don’t modulate the blower speed,
check S/A Static Pressure pressure hose orientation
and make sure the t-stat call
is the same as the trimpot
being adjusted.

- Hertz will be displayed on the Variable Frequency Drive digital display.
- Outlet velocity is based on ideal noise levels.
- Static Pressure reading must be taken perpendicular to airflow, minimum
of 18” away from supply air collar of fan coil.
- Quick references should only be used to roughly set fan coil, not
to be used as primary fan coil set up method.
