ReliaTel Test Mode
Resistance Test
Specific operating states can be selected by applying an appropriate resistance from TEST 1 to
TEST 2.
Operating modes can be changed in any order by applying the correct resistance values. Operation
in any one mode is limited to 60 minutes as with the jumper method.
*Optional components
**defrost cycle in test mode runs for at least 1 minute, up to 10 minutes, depending on outdoor ambient and outdoor coil temperature.
Reheat step is valid only with dehumidification option and will be step 5 of the test.
Step Test
By placing a jumper from TEST 1 to TEST 2 for 2 continuous seconds nominal, allowing the unit
to energize the mode for at least 2 seconds, then placing the jumper again, the unit can be scrolled
through modes as in method 1 but more quickly. Unused states, such as Heat 2 when no Heat 2 is
present, shall be skipped.
Note: 27.5-50 ton units see test mode chart Table 17 on page 53 and Table 18 on page 54.
