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)

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.
