d. Press "SYSTEM" to select the desired system test:

A. Cooling mode: Select "TE ST COOL" followed by “Next” and choose the hig hest stage available. Press

"T EST" to begin testing in the selected mode

B. Heating mode: Select "TE ST COMPR ESSOR H EAT" followed by “Next” and choose the hig hest stage

available. Press the "TEST" button to begin testing in selected mode

C. I f t he " TEST COMPRESSOR HEAT" option is not displayed, return to the home screen and make a large

call for heat of at least 10 degrees. Please Note: if OAT is less than Au xiliary H eat L ock ou t temp erature

setpoint the auxiliary heat may engage

e. Each test will run for a maximum of 60 minutes or until manually terminated
f. Wait at least 10 minutes before taking static pressure readings and inserting flow plate for TrueFlow plate

test. Listen to ensure fan has staged up completely

g. Wait at least 20-25 minutes before doing temp split readings for refrigerant test. The longer the system is

allowed to run, the more likely it will reach a steady state

b. A call for HEATING or COOLING will typically never force the unit into full compressor and fan speed. Use the

following steps to determine the percent of compressor speed the system is opera ting at :
A. If the Compressor Speed Widget is enabled, the thermostat will display the percent of compressor

speed on the home screen

B. If the Compressor Speed Widget is not displayed on the home screen, from the Service Menu (accessed

in Step 1a-1c) press “System Report”. The percent of compressor speed will be displayed as “%

c. For both methods A and B a bove, let the system run for at least 20 minutes to reach steady state. Supply
