Verify that the return fan IGVs, if so equipped, return to their fully closed position. If equipped with single- stage

 

 

analog humidi®cation control, verify that the modulating valve goes to its fully open position. If equipped with

 

 

two stages of humidi®cation, use an ohmmeter to verify that the reading across the 1st stage normally-open

 

 

relay contacts is less than 10 ohms.

 

HUM2 %

Verify that the reading across the 1st stage normally-open relay contacts is greater than 1000 ohms.

 

HUM2TEST

If equipped with two stages of humidi®cation, use an ohmmeter to verify that the reading across the 2nd stage

 

normally open relay contacts is less than 10 ohms.

 

 

 

AOTC %

If equipped with two stages of humidi®cation, verify that the reading across the 2nd stage humidi®cation nor-

 

mally open relay contacts is greater than 100 ohms.

 

 

 

AOTCTEST

Verify that the analog device connected to this output strokes to its 100% position.

 

DOTC X

Verify that the analog device connected to this output strokes to its 0% position.

 

DOTCTEST

Using an ohmmeter, verify that the reading across the DOTC (Discrete Output Temperature Control) normally

 

open relay contacts is less than 10 ohms.

 

 

 

DTCC X

Using an ohmmeter, verify that the reading across the DOTC normally open relay contacts is greater than 1000

 

ohms.

 

 

 

DTCCTEST

Using an ohmmeter, verify that the reading across the DTCC (Discrete Timeclock Control) normally open relay

 

 

contacts is less than 10 ohms. Proceed with the testing of electric heat stages (Table 21). If the unit is not

 

 

equipped with electric heat, exit the Quick Test mode as described below:
