CONVENTIONAL THERMOSTAT WIRING
The (-)H2V series air handler is shipped with “On Demand Dehumidification” (ODD)
turned OFF. On Demand Dehumidification is used in conjunction with a traditional
24VAC thermostat equipped with an on-board humidity sensor. Activate ODD by turning
DIP switch 7 ON. ODD operation is controlled by the indoor humidity sensed at the ther-
mostat. Operation is:
Normal Humidity (humidity BELOW the thermostat set point):
H
igh Humidity (humidity ABOVE the thermostat set point):
The (-)H2V air handler is programmed to provide maximum efficiency and optimum
humidity removal. When high humidity is detected, the air handler reduces cooling air-
flow defined in Table 6.
IMPORTANT: The DIP switches are active only when using conventional a 24VAC ther-
mostat. If using the Comfort Control
2
System™, refer to Section 5.4 for adjusting air-
flows.
NOTE: ODD airflow adjustments are active for cooling operation only. They are ignored
when the heat pump is in heating mode or when electric heat is activated.
6.16 COOLING DELAY PROFILES (-)H2V
Cooling delay profiles are not available when the H2V air handler is controlled using a
conventional 24VAC thermostat. These profiles are available only when the air handler
is wired for the Comfort Control
2
System™. Refer to Section 5.4 for the Comfort Control
2
Cooling Delay Profiles.
