T7350 Commercial Programmable
Thermostat
FOR SINGLE- OR MULTI-STAGE CONVENTIONAL/
HEAT PUMP SYSTEMS
APPLICATION
The T7350 Commercial Programmable Thermostat
controls 24 Vac commercial single zone heating,
ventilating and air conditioning (HVAC) equipment. The
T7350 consists of a thermostat and subbase. The
thermostat includes the display and keypad for 7-day
programming. The subbase includes equipment control
connections. The subbase mounts on the wall and the
thermostat mounts to the subbase.
MERCURY NOTICE
If this control is replacing a control that contains
mercury in a sealed tube, do not place your old
control in the trash. Dispose of properly.
Contact your local waste management authority
for instructions regarding recycling and the
proper disposal of an old control. If you have
questions, call Honeywell Customer Care Center
at 1-800-468-1502.
INSTALLATION
When Installing this Product...
1.
Read these instructions carefully. Failure to follow
them could damage the product or cause a
hazardous condition.
2.
Check ratings given in instructions and on the
product to ensure the product is suitable for your
application.
3.
Installer must be a trained, experienced service
technician.
4.
After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Electrical Shock or Equipment Damage
Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply before installation.
Location
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.
IMPORTANT
To avoid electrical interference, which can
cause erratic performances, keep wiring runs as
short as possible and do not run thermostat
wires adjacent to the line voltage electrical
distribution systems. Use shielded cable. The
cable shield must be grounded only at the
controlled equipment case.
Subbase
WHEN USED TO SENSE ROOM TEMPERATURE
Install the thermostat about 5 ft. (1.5m) above the floor in
an area with good air circulation at average temperature.
(See Fig. 1.)
WHEN NOT USED TO SENSE ROOM TEMPERATURE
When using the remote-mounted temperature (and
humidity) sensor(s) to sense ambient conditions, install
the thermostat in an area that is accessible for setting
and adjusting the temperature and settings.
CAUTION
Equipment Damage Hazard.
Can damage the TIM connection beyond
repair.
Disconnect the TIM cable prior to opening or
closing the thermostat cover.
NOTE: Allow sufficient clearance below the thermostat
to plug in the TIM cable.
Install the remote-mounted sensor(s) about 5 ft. (1.5m)
above the floor in an area with good air circulation at
average temperature. (See Fig. 1.)
If multiple remote sensors are required, they must be
arranged in a temperature averaging network consisting
of four sensors. (See Fig. 2.)
