Thermostat Installation - Honeywell SERIES COMMUNICATING TB7600 Installation Instructions Manual

TB7600 SERIES COMMUNICATING RTU/HEAT PUMP THERMOSTATS
CAUTION
Electronic controls are static sensitive devices. Discharge yourself properly before manipulation and installing
the thermostat.
Short circuit or wrong wiring may permanently damage the thermostat or the equipment.
Anti-short cycling can be set to 0 minutes for equipment that has an anti-cycling timer. Do not set to 0 unless the
equipment has an internal anti-cycling timer or damage to equipment can occur.
All TB7600 Series thermostats are to be used only as operating controls. Whenever a control failure could lead
to personal injury and/or loss of property, it becomes the responsibility of the user to add safety devices and/
or alarm system to protect against such catastrophic failures.
