UV-SVP01A-EN 49
If a two-blink pattern remains after
an attempt to clear diagnostics,
the diagnostic condition is still
present and may affect the manual
output test. The diagnostic must
then be cleared using another
method.
(See “Resetting Diagnostics” on
page54.for more information.)
Test Procedure
The procedure for testing is:
1. Press and hold the Test button
for at least two seconds, then
release the button to start the
test mode.
2. When manual output test
mode begins, the controller
turns off all outputs and cali-
brates modulating end
devices closed.
3. Press the Test button once to
advance through the test
sequence.
Note: To help ensure accurate
testing do not press the test
button more than once per
second.
Alternatively, the manual output
test can be controlled over the
communications network by using
Rover.
When conducting the manual out-
put test via communications net-
work, the sequence must start with
Step 1 (
OFF), as shown in Table 26:
Test sequence for non face-and-bypass unit
configurations
and Table 27: Test se-
quence for face-and-bypass unit configura-
tions However, subsequent steps
may be conducted in any order.
1. Upon entering manual output test mode, the controller turns off all fan, DX, and electric heat outputs and drives all dampers and valves
closed (if required).
2. At the beginning of step 2, the controller attempts to clear all diagnostics.
3. If the unit is configured for a 3-speed fan, the medium fan speed output will energize at step 3. If the unit is configured for a 2-speed fan,
the fan remains on high speed at step 3.
4. If the unit is configured for a 3-speed fan, the medium fan speed output energizes at step 3. If the unit is configured for a 2-speed fan, the
low fan speed output energizes at step 3. If the unit is configured for a 1-speed fan, the fan remains on high speed at step 3.
5. If the unit is configured for a 1- or 2-speed fan, the exhaust fan output energizes on step 7. The exhaust fan output is shared with medium
fan speed.
6. After step 10, the test sequence performs an exit. This initiates a reset and attempts to return the controller to normal operation
