Honeywell Tradeline T834C Mode D'emploi

TRADELINE
The T834C Heating-Cooling Thermostats provide 24
to 30 Vac control in heating-cooling systems. An spdt
mercury switch makes R to W on a temperature fall for
heating, and R to Y on a temperature rise for cooling.
Integral switches control HEAT-OFF-COOL system op-
eration and AUTO-ON fan operation. See Fig. 1. Models
available for gas or oil heat/ conventional cooling systems
with common or separate R terminals and for single-stage
heat pump systems.

3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Disconnect power supply before beginning in-
stallation to prevent electrical shock or equip-
ment damage.
LOCATION
Locate the thermostat about 5 ft [1.5 m] above the floor
in an area with good air circulation at average temperature.
Do not mount the thermostat where it can be affected by:
— drafts or dead spots behind doors or in corners.
— hot or cold air from ducts.
— radiant heat from the sun, fireplaces, or appliances,
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall
behind the thermostat.
MOUNTING AND WIRING
Disconnect power supply before beginning installation
to prevent electrical shock or equipment damage.
All wiring must comply with local codes and ordinances.
The T834C can be mounted directly on a wall or
vertical outlet box. Use the 193121A Mounting Plate As-
sembly (order separately) to mount on horizontal outlet box
or cover marks left by old thermostat. If mounting plate
assembly is used, review instructions provided with assem-
bly before wiring and mounting thermostat.
To wire and mount thermostat:
1. In replacement applications, check the existing ther-
mostat wires for cracked or frayed insulation. Replace any
wires in poor condition. If the wire is plastered into the
wall, make a hole next to the wires and loosen the wires so
they can be pushed back into the wall later.
2. In new installations, run wiring (if necessary) to the
thermostat location.
3. Connect the wires to the terminals on the back of the
thermostat. See Figs. 2-4 for internal schematic and typical
hookup diagrams.
4. Remove thermostat cover by pulling outward on
bottom edge of cover until it snaps free of the thermostat
base. Carefully remove and discard the foam plastic ship-
ping insert that protects the switch and bimetal assembly
during shipping.
5. Set the adjustable heat anticipator indicator to
match the current draw of the primary heating control (see
Heat Anticipator Setting).
6. Push excess wire back through the hole and plug
any opening with insulation to prevent drafts that may
affect thermostat performance.
