DEHUMIDISTAT CONTROL SETTING & ADJUSTMENT

A dehumidistat wired in parallel may be used to maintain the relative humidity level during unoccupied times re- gardless of ambient temperature. By cycling an air conditioning system the relative humidity is maintained to help prevent high humidity levels which are associated with mold and mildew build-up.

CAUTION

Do not use parallel wiring if compressor is not equiped with low temperature protection. Oper- ating compressor without low temperature pro- tection will damage compressor and could cause personal injury and/or property damage.

1.A relative humidity environment of 50-55% is desir- able during the summer. To achive this the cooling thermostat would be set at a higher than occupied temperature or off. The dehumidistat will cycle the air conditioning system as required to maintain the rela- tive humidity setting.

2.An operational check can be made as follows:

a.Turn dehumidistat knob to "ON" position. The cooling system and blower should start.

b.Then rotate knob to desired setting.
