HUMIDIFICATION — HOW IT WORKS
DISPLAY, BASIC AND PRECISION—These modes allow user control
of relative humidity between 15 and 45%. Individual humidification
control mode conditions are as follows:
DISPLAY Only mode indicates humidification is OFF.
BASIC mode also requires presence of heating demand [Y for HP
heat, or W for gas heat (W may be energized with G de-energized)].
— humidification mode has been enabled
— the unit is in HEAT mode
— humidification demand exists (24V present at H).
PRECISION mode indicates:
— humidification mode has been enabled
— the unit is in HEAT mode
— humidification demand exists (24V present at H).
BASIC DEW POINT CONTROL mode (requires outdoor temperature sensor installation) will change the
humidification set point based on:
— outdoor temperature
— user-defined dew point adjustment setting.
PRECISION DEW POINT CONTROL mode (requires outdoor temperature sensor installation) will operate when the
following conditions are met:
— outdoor temperature
— humidification mode has been enabled
— humidification demand exists (24V present at H)
— the unit is in HEAT mode.
