Honeywell T7200D, T7200E Installation Instructions Manual

T7200D,E Series 2000 Commercial
Microelectronic Thermostats
INSTALLATION INSTRUCTIONS
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.
If this control is replacing a control that contains mercury in a sealed tube, do control in the trash.
Contact your local waste management authority for instructions regarding recycling and the proper disposal of the old thermostat.

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.
WALL
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.

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 equip­ment 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.

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. — To enter the Installer Setup mode, press and hold the
Heat/Cool Settings key while pressing both the increaseand decrease ▼ keys until the first number is displayed. All display segments appear for approximately three seconds before the number is displayed. See Fig. 8 and 9.
— To advance to the next Installer Setup number, press
the Unoccupied Temp key.
— To return to a previous Installer Setup number, press
the Heat/Cool Settings key.
— To change a setting, use the increaseor decrease
key.
— To exit the Installer Setup, press the Run Program
key. The Installer Setup is automatically exited if no key presses are made for four minutes.

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 column. When Installer Setup is com­plete, review the settings to confirm that they match the system.
