Existing Applications
Remove the cover of the old thermostat. If it does not come
off easily check for screws.
Loosen the screws holding the thermostat base or subbase
to the wall and lift away.
Disconnect the wires from the old thermostat. Tape the ends
of the wires as you disconnect them and mark them with the
letter of the terminal for easy reconnection to the new
thermostat.
Keep the old thermostat for reference purposes until your
new thermostat is functioning properly.
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical connections
to avoid electric shock.
CAUTION: Risk of Property Damage.
Do not apply power to the system before checking all wire
connections. Short circuited or improperly connected wires
may result in permanent damage to the equipment.
IMPORTANT: Make all wiring connections in accordance with local,
national, and regional regulations. Do not exceed the electrical ratings
of the T701 Series Thermostat Controller.
Note: This thermostat is strictly a low voltage control. A compatible
relay board must be installed to isolate the 24 volt wires from the line
voltage to the fan.
