33. W**G DEHUMIDIFICATION RELAY LOGIC BOARD
DEHUMIDIFICATION RELAY LOGIC BOARD
Cooling takes precedence over dehumidification. A cooling call cancels dehumidification.
First stage heating cancels dehumidification.
If jumper on RLB is set to “1-2 full-time dehumidification”, outputs will energize. This is the factory default
setting. If jumper is set to “2-3 occupied dehumidification only”, outputs will be off.
