DIVERSITECH TOUCH SCREEN THERMOSTAT INSTALLATION
SELECTING A LOCATION
Install your DiversiTech thermostat approximately 5 feet (1.5 meters) above the floor in an
area with good air circulation.
Avoid the following locations:
• Hot or cold air from ducts
• Radiant heat for appliances or sun such as a skylight
• Unheated areas or uncooled areas:
for example an outside wall behind the thermostat.
6
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).
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.
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.

DIVERSITECH TOUCH SCREEN THERMOSTAT INSTALLATION
MOUNTING THE THERMOSTAT TO THE WALL
1. Make sure to turn off the power supply located at the electrical service panel.
All heating and cooling units should be OFF.
2. Remove the cover plate by pulling up the cover from the left or right side only.
3. Align the thermostat unit to the wall.
4. Mark the two locations for drilling the 3/16” holes required for the plastic screw anchors.
5. Remove the thermostat and drill the two 3/16” holes in these locations.
6. Insert the plastic gyproc screw anchors and tighten them securely.
7. Make the appropriate wire connections based on the specifications of the
household HVAC unit(s). Please refer to Wiring Table to determine the appropriate
wire connections.
8. Securely mount the thermostat unit to the wall with the two supplied screws.
9. Fit the cover plate back by clipping one side first (left or right) and than push down

ADVANCED SETTINGS – TIMER FEATURE
• Specify the number of minutes for which Stage 1 will function until Stage 2 is
activated to help raise (or cool) temperature (if the temperature set point is not
reached). This unique function avoids excess compressor wear in the case where
the necessary temperature set point is not met through setting of the Staging
Differentials. Set to “00” to disable.

®CALIBRATION OF TEMPERATURE
Your DiversiTech thermostat is rated for +/-1° temperature accuracy.
• If you have determined due to drafts, sunlight or other environmental factors that your
thermostat needs calibration, follow this easy guide. Common causes of offset are
lack of air circulation in the vicinity of your DiversiTech thermostat or skylights.

TROUBLESHOOTING
•Touch screen buttons do not function properly. Remove cover, press the reset
button located in the bottom left corner then accurately touch 3 target centers on
the screen when prompted.
•Air conditioning turns on in HEAT mode and heating turns on in COOL mode.
Reverse the OB valve (see “Advanced Settings” Page 31).
•PARTIAL LOCK and FULL LOCK do not function. You must not touch the screen
for 1 minute for DiversiTech thermostat to automatically lock.
•Thermostat appears normal until the screen becomes blank when the com-
pressor or heating system turns on. You need to connect the “C” wire. 4 wire
system will not function unless the heat and compressor contactors can supply enough
current to power the thermostat with only 4 wires, if you cannot hook up the “C”
wire another possible solution is to connect one 250 ohm 10 watt resistor in the
HVAC room, for cooling problems between C and W or in the case of heating prob-
lem between C and Y1.
•I forgot my PIN and cannot unlock the thermostat. Remove the cover plate, press
the reset button located in the bottom right corner, as soon as the message “touch
to reset password” appears touch the screen, your PIN will be erased and the ther-
mostat will unlock.
36
SIMPLE THERMOSTAT MODE
®DIVERSITECH THERMOSTAT CAN ALSO FUNCTION AS A NON-PRO-
GRAMMABLE THERMOSTAT AFTER IT HAS BEEN CONFIGURED.
• To enable “Simple Mode”, press the reset button (take off the thermostat face-
plate and press the reset button located in the bottom right-hand corner). The
message “Touch for simple thermostat” will appear. Touch the screen, and
DiversiTech thermostat becomes a simplified non-programmable thermostat.
• Please note that when changing to Simple Mode, you will not lose any of the
settings you have previously entered in the “Programmable Mode”.
• To revert back to the Programmable DiversiTech thermostat, simply press the
reset button and touch the screen when the message “Touch for Programmable
Thermostat” appears.
Simple Mode has the following basic features:

IMPORTANT NOTICE
®WHEN USING THIS THERMOSTAT WITH A GAS FURNACE
A COMMON WIRE (C) MUST BE CONNECTED.
•When working without a common wire:
Aconfirm in heat mode the cooling does not switch on or Bconfirm in cooling mode
the heat does not switch on.
• If test Aor Bfail or the thermostat shuts down in either heat or cool mode then it is
necessary to connect a common wire, (C), alternatively it may be possible to solve
this issue by simply connecting the 250 ohm 10 watt resistor between C and W (in
the case of a cooling problem – see B) or between C and Y1 (in the case of a heat-
ing problem - see A) at the HVAC equipment.
• When working without a common wire, Aconfirm that when there is a call for heat,
cooling does not also activate, and when there is a call for cool, heating does not
also activate.
• If using the configuration of Heat Pump and Furnace with no Common Wire con-
firm that when Heat Pump and Furnace are working together (both stages are oper-
ating at the same time) that the display does not go blank, if so you must use a
Common Wire.
• This thermostat is equipped to run with two separated power transformers if required
RC and RH. Terminals RC and RH are internally connected together however you
should wish to use two transformers simply cut with a blade the copper trace on
the printed circuit board located between the C and Y2 screw terminals.
