Honeywell T7200D User manual

APPLICATION
The T7200D,E Thermostats provide electronic control of
24 Vac commercial single-zone heating, ventilating and air
conditioning (HVAC) equipment. The T7200 is field
configurable for automatic or manual changeover between
heating and cooling. The system and fan selections are
made by keyboard entry. All T7200 Thermostats require a
common wire to supply power.
RECYCLING NOTICE
If this control is replacing a control that contains
mercury in a sealed tube, do
not place your old
control in the trash.
Contact your local waste management authority for
instructions regarding recycling and the proper
disposal of the old thermostat.

the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After completing installation, use these instructions

T7200D,E SERIES 2000 COMMERCIAL MICROELECTRONIC THERMOSTATS
Do not install the thermostat where it can be affected by:
—drafts, or dead spots behind doors and in corners.
—hot or cold air from ducts.
—radiant heat from sun or appliances.
—concealed pipes and chimneys.
—unheated (uncooled) areas such as an outside wall
behind the thermostat.
Mounting Wallplate
The wallplate mounts horizontally on the wall or on a
2 in. x 4 in. wiring box. Position the wallplate horizontally
on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the wallplate (for appearance
only). The thermostat functions properly even when
not level.
2. Use a pencil to mark the mounting holes. See Fig. 2.
3. Remove the wallplate from the wall and drill two
3/16 inch (4.8 mm) holes in the wall (if drywall) as
marked. For firmer material such as plaster or wood,
drill two 7/32 inch (5.5 mm) holes. Gently tap
anchors (provided) into the drilled holes until flush
with the wall.
4. Position the wallplate over the holes, pulling wires
through the wiring opening.
5. Loosely insert the mounting screws into the holes.
6. Tighten mounting screws.
CAUTION
Electrical Shock Hazard.
Power source can cause electrical shock.
Disconnect power before wiring to prevent
electrical shock or equipment damage.
1. Loosen the terminal screws on the wallplate and
connect the system wires. See Fig. 3.
IMPORTANT
Use 18-gauge, solid-conductor color-coded
thermostat cable for proper wiring. If using
18-gauge stranded wire, do not use more than
ten wires. Do not use larger than 18-gauge wire.
2. Securely tighten each terminal screw.
3. Push excess wire back into the hole.
4. Plug the hole with nonflammable insulation to
prevent drafts from affecting the thermostat.
Fig. 2. Mounting the wallplate.
WIRING WALLPLATE
All wiring must comply with local electrical codes and
ordinances. Follow equipment manufacturer wiring
instructions when available. Refer to Fig. 4 and 5 for
typical hookups. A letter code is located near each
terminal for identification.

CAUTION
Possible Equipment Damage.
Fan must be running when system is
operating.
Configure heat pump and electric heat systems in
Installer Setup 2 to prevent equipment damage
caused by the system running without the fan.
IMPORTANT
Only configurable numbers are shown on the
device. Example: If the thermostat does not have
a system key, Installer Setup Number 12 will not
be displayed. Review Table 2 factory settings
and mark any desired changes in the Actual

Setting System and Fan (select models)
The system default setting is Heat. The fan default is set
so the fan operates continuously in the Occupied and
Recovery modes and with the heating or cooling equip-
ment in the Unoccupied mode. Use the System and Fan
keys to change the settings.
The system settings are:
Heat: Thermostat controls the heating.
Off: Both the heating and cooling are off.
Cool: Thermostat controls the cooling.
Auto: Thermostat automatically changes between
heating and cooling operation depending on the
indoor temperature.
The fan settings are:
On: Fan operates continuously.
Auto: Equipment controls the fan in the Unoccupied
mode. The Intelligent Fan™ operation (Installer
Setup number 17) offers three choices for the fan
operation in Occupied mode:
—fan turns on only when there is a call for heating
or cooling,
—fan operates continuously in Occupied mode,
—fan is on continuously in Occupied and recovery
modes.
Setting Temperature
Refer to Table 1 for the default temperature setpoints. See
Owners Guide, form number 63-4356, for complete
instructions on changing the setpoints.
Table 1. Default Temperature Setpoints.
INSTALLER SETUP
NOTE: For most applications, the thermostat factory-
settings do not need to be changed. Review the
factory-settings in Table 2 and if no changes are
necessary, go to the Installer System Test
section.
The Installer Setup is used by the installer to customize
the thermostat to specific systems. Installer Setup
numbers are listed in Table 2. The table includes all the
configuration options available.
A combination of key presses are required to use the
Installer Setup feature.
