electrical shock and may result in severe personal injury or death.
* Risk of Electrical Shock
Ground the thermostat according to local, naonal, and regional regulaons.
Failure to ground the thermostat may result in electrical shock and severe personal injury and death.
* Risk of Electrical Shock and Property Damage
Insulate and secure each unused wire lead before applying power to the thermostat. Failure to insulate and secure each unused
wire lead may result property damage, electrical shock, and severe personal injury or death.
* Do not apply power to the system before checking all wiring connecons. Short circuited or improperly connected wires may
result in permanent damage to the equipment.
