DIVERSITECH TOUCH SCREEN THERMOSTAT CONFIGURATION

ADVANCED SETTINGS – HUMIDIFICATION & DEHUMIDIFICATION

HUM FAN:

ON: fan runs when there is an independent demand to humidify. OFF:

fan only runs when there is a demand to humidify while heating or cooling. 

DH FAN:

ON: fan runs when there is an independent demand to dehumidify. OFF:

fan only runs when there is a demand to dehumidify while cooling.

DH REVERSE:

ON: DH relay is normally closed when relative humidity is above DH

set point. OFF: DH relay is normally open when relative humidity is above DH set point.

DH CONTROL COMPRESSOR:

ON: Thermostat will turn off the air conditioning

if either the dehumidify set point or the temperature set point is reached, whichev-
er comes first, both DH relay and compressor will turn off. OFF: DH relay is inde-
pendent of compressor activity (DH becomes a spare relay and can be used for a
variable speed fan or separate dehumidifier or air exchanger)

ADVANCED SETTINGS – HUMIDIFICATION & DEHUMIDIFICATION

®

OPERATING TIPS

Humidification Fan

should be 

set to on

when running steam or mist humidifiers. 

Humidification Fan

should be 

set to off 

when running drum humidifiers or any 

other humidifier that requires the furnace to run in order to make humidity. 

De-Humidification Fan (DH)

should be 

set to on

when running separate de-humid-

ification equipment. 

De-Humidification Fan (DH) 

may be 

set to off 

when using the air conditioning as a

means of de-humidification. It may advantageous in some environments to turn the
fan on independently when there is a call for 

DH

in order to distribute the humidity

level more evenly. 

The

DH REVERSE

function can be configured to meet the requirements of many

variable speed fans, consult the manual of your variable speed fan and determine
if an “open” or “closed” contact results in slowing fan operation.
