Anticipator control – Anticipator control
is used to turn off the heating equipment
before the room temperature actually
reaches the cut-out point.
Cut-in Point – The air temperature at the
thermostat at which it initiates action of
heating/cooling equipment.
Cut-out Point – The air temperature at the
thermostat at which it terminates action of
heating/cooling equipment.
Cycle rate – Cycle rate is the frequency
that heating or cooling equipment is turned
on during a certain period of time. Cycle rate
is often given in units of cycles per hour
(CPH).
Dehumidify – The process of removing
moisture from the air.
Dehumidifier – Device used to remove
moisture from the air.
Differential – Differential is defined as
the difference between the cut-in and
cut-out points as measured at the
thermostat under specified operating
conditions. For example, if the thermostat
turns the heating equipment on at 70
degrees F and turns the heating equipment
off at 74 degrees F, then the differential is
4 degrees F.
Humidifier – A device used to add
moisture to a space.
Humidistat – A control which is operates
the humidifier and is affected by changing
humidity.
Humidity – Moisture in the air.
Programmable thermostat – A thermo-
stat with the capability of automatically
adjusting temperature set point to pre-
selected settings at pre-selected times.
Setback – The automatic alteration of the
thermostat control point(s) by means other
than manually changing the temperature set
point.
Set point – The desired temperature
setting on an electromechanical or
electronic thermostat.
GLOSSARY OF TERMS DIVERSITECH TOUCH SCREEN THERMOSTAT INSTALLATION

DIVERSITECH TOUCH SCREEN THERMOSTAT OPERATION
THERMOSTAT OPERATION MODES
• Your DiversiTech thermostat can run in Program Mode or can hold a fixed
temperature.
•RUN PROGRAM: Your custom program settings will be initiated - 4 events per
day including the fan mode
•HOLD TEMPERATURE: Allows you to raise or lower the temperature setpoint
by touching the heat/cool - to lower + to raise
DIVERSITECH TOUCH SCREEN THERMOSTAT OPERATION
TEMPERATURE SETPOINTS
•AUTO, HEAT, COOL AND OFF
Based on your HVAC equipment you can quickly and easily select the mode
of operation - Automatic • Heat • Cool • Off
• AUTO – choose your heat and cool temperature setpoints – the temperature
will automatically adjust according to the requirement
• HEAT – choose your Heat setpoint
• COOL – choose your Cool setpoint
• OFF - no heating or cooling
•PROGRAM TEMPERATURE SETPOINT:
• Choose HEAT: Heat will appear with a temperature range, select your temperature
• Choose COOL: Cool will appear with a temperature range, select your temperature
• Choose AUTO: A combined heat/cool button will appear – when heat flashes
– choose your temperature setpoint, touch the button to toggle to cool, then
set your temperature setpoint.

DIVERSITECH TOUCH SCREEN THERMOSTAT OPERATION
HUMIDIFICATION AND DE-HUMIDIFICATION SETPOINTS
•DE-HUMIDIFY: Allows you to reduce and maintain the relative humidity to a spe-
cific setpoint. Please note that this feature functions in the Cool Mode only. Your
DiversiTech thermostat must be configured to control a cooling unit such as an
air conditioner of heat pump. Once you choose De-Humidify follow these easy steps:
• The DH setpoint with – and + icons allow you to lower and raise your setpoint
• Example of typical use of the De-Humidify function: If the current humidity is 70% your
DiversiTech thermostat will initiate the humidifier to function until Setpoint 50% in this reached.
In order to de-humidify you must set the de-humidify setpoint below the current relative
humidity. Your DiversiTech thermostat will both lower and regulate temperature to the cool-
ing setpoint while monitoring and lowering the room humidity.
• Since the De-Humidify feature uses the Cool Function of your Air Conditioner or Heat
Pump, your DiversiTech thermostat will turn off the air conditioning if either the dehu-
midifier setpoint or temperature setpoint is reached – which ever comes first.
DIVERSITECH TOUCH SCREEN THERMOSTAT OPERATION
HUMIDIFICATION AND DE-HUMIDIFICATION SETPOINTS
®In order to reduce condensation, humidity must be controlled and air
movement must be generated. As the exterior temperature drops, the
humidity level needs to decrease if condensation is to be controlled.
•HUMIDIFY: Allows you to raise and maintain the relative humidity to a specific set-
point. Once you choose Humidify follow these easy steps:
• The HUM setpoint with – and + icons allow you to lower and raise your setpoint.
• Example of the typical use of the Humidify Function: If the current humidity is 30% your
DiversiTech thermostat will initiate the humidifier to function until Setpoint 50% is reached.
In order to humidify you must set the humidity setpoint above the current humidity.

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)
DIVERSITECH TOUCH SCREEN THERMOSTAT CONFIGURATION
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.
