Disconnect Power To All Hvac Equipment And/Or Zone Control Panels - Aprilaire 8800 System Installation Manual

MODEL 8051, 8052 AND 8053 REMOTE TEMPERATURE SENSORS (OPTIONAL)
These sensors can be used directly with the Model 8800 thermostat or with support modules.
Model 8051 Flush Mount Sensor
FOR EASE OF INSTALLATION AND TROUBLESHOOTING DO THE FOLLOWING:
• Use Category-5 cable for all communication wiring.
• Check and recheck to ensure connection to the proper terminals before powering up the thermostats. Use wire color as a guide and be consistent.
• Use a Distribution Panel on all systems with more than one zone to simplify wiring and troubleshooting.

DISCONNECT POWER TO ALL HVAC EQUIPMENT AND/OR ZONE CONTROL PANELS

• If the thermostats are wired to a zone control panel, there is generally one set of input terminals supplying power to the thermostats and
dampers. This must be disconnected.
• If the thermostats are wired directly to HVAC equipment, the power must be shut off at the equipment. This can generally be accomplished by
turning off the disconnect switch located near the equipment. If an obvious disconnect switch is unavailable, you will need to turn the circuit
off using the fuse or circuit breaker. Remove the fuse or shut down the circuit breaker serving the equipment.
Failure to disconnect power could result in damage to the HVAC equipment or thermostats. Leave power disconnected until all other
electrical connections have been made and checked for accuracy.
