TABLE 14

DEHUMIDIFICATION RELAY LOGIC BOARD

NOTES:

Cooling takes precedence over dehumidification. A cooling call cancels dehumidification

Dehumidification takes precedence over 1st stage heating. The first stage heating call is redirected from compressor heating to electric heat.

2nd stage heating cancels dehumidification.
