System Test Mode

Touching the SYSTEM TEST MODE button on the ADVANCED 2/2 display will bring up the SYSTEM TEST screen, from

which technicians can verify the devices connected to the UbiquiSTAT.

NOTE:

Improper use of the testing mode can damage equipment connected to the HVAC system. Testing must only be

performed by experienced, accredited HVAC technicians.

During testing, all internal control logic is disabled and outputs will revert to inactive or zero percent.

• Relay Inputs (W1, W2, Y1, Y2, G, B/O, TC): Touching the Relay Outputs buttons activates the connected equipment

(after a three-second delay). Touching a heating or cooling relay button also activates the fan. Touching the fan relay

button again will then turn off the fan without turning off the heating or cooling relays.

• Analog Outputs (AO1, AO2): The mA output shows the actual signal from the output device. You can adjust the

analog outputs up or down in increments of 10%.

• Control Testing (Heat, Cool): Activate either button to simulate a large load for 10 minutes. Heat/cool lockouts will

be disabled, while discharge air limits will continue to operate. Affected AOs will operate at their maximum (manual

AO testing is disabled.)

• Input Readings (Temperature, Digital Inputs, Analog Inputs): Located in the bottom half of the screen, inputs are

updated every second. The temperature and analog inputs (T1, T2, T3, Internal, A1, A2) show the actual signal value.

The digital inputs D1, D2, D3) show the description and status.
