TABLE 12
DEHUMIDIFICATION RELAY LOGIC BOARD
NOTES:
1. Cooling takes precedence over dehumidification. A cooling call will cancel dehumidification.
2. Dehumidification takes precedence over first stage heating.
3. A second stage heating call cancels dehumidification.
4. The relay logic board has a jumper on it to choose between full-time dehumidification and occupied dehumidification only. With
the jumper in the 1-2 position dehumidification is available full-time. With the jumper in the 2-3 position dehumidification is
available only when the room is occupied. The room is considered occupied when the A1 terminal is energized.
5. These outputs will be energized if the jumper is in the full time dehumidification position. They will be off if the jumper is in the
occupied dehumidification only position.
