Problem Possible causes Possible solutions
Circuit breaker open

Reset the breaker.
Variable speed 1 or variable
speed 2 fan switches on, runs
at full speed, and then turns off. The hysteresis is not high enough.
The outside temperature is rising
and falling quickly. This happens
most often in the spring and fall.

Adjust the hysteresis setting or overlap the
variable speed 1 or variable speed 2 fan
settings. For more information, read
Configuring hysteresis on page 27.
Variable speed fan responds to
only a small portion of the 0 to
100% range
Incorrect motor curve

Configure the stage to use the other motor
curve. For more information, read
Configuring variable stages on page 32.
Curtain opens when it should
close or closes when it should
open
Incorrect wiring, the close and
open wires are reversed.

Correct the wiring. For more information,
read Connecting curtain machines on page
16
Staged heater cycles on and off The heater set points are too
close to the variable speed fan set
points.

Adjust the set points to be farther apart. For
more information, read Programming
variable cooling stages on page 49, or
Programming variable heating stages on
page 51.
The heater is too large for the
room

Replace the heater with a smaller output
unit.
The stage is set up as a duty
cycle

Configure the relay as heating. For more
information, read Configuring relays for

Check the power and circuit breaker for the
load.
Faulty equipment

Manually test the equipment and repair or
replace it if necessary.
Blown relay
