The Honeywell T280R is a temperature probe for the 5821 wireless temperature sensor and water sensor. When using the T280R temperature probe with the 5821 wireless sensor, you can monitor the temperature of refrigerators and freezers in restaurants, kitchens, laboratories and warehouses where cold temperature is critical. The T280R is also ideal for wine cellars, flower shops and butcher shops. The 5821 wireless temperature sensor can be programmed for either freezing temperature monitoring or refrigerator temperature monitoring when using the T280R temperature probe.
When programmed with the freezing temperature setting, an alarm will be triggered if the probe detects temperatures over 10° F for greater than (30) minutes. The wireless sensor will restore automatically when the temperature drops below 7° F for more than (4) minutes. When programmed to refrigerator temperature monitoring, an alarm will be triggered when the T280R detects temperatures above 42° F for more than (30) minutes and the alarm will restore when the temperature drops below 39° F for more than (4) minutes. These temperatures are hard coded into the programming of the 5821 wireless temperature sensor and cannot be changed. The (30) minute preset delay prevents false alarms due to normal openings of refrigerator or freezer doors.
You should mount the 5821 outside of the refrigerator or freezer and only install the T280R temperature probe inside to prevent a loss of wireless signal strength back to your wireless alarm system.
If you are using the T280R temperature probe with a 5821 wireless sensor, you cannot also use the 470PB water probe. Only (1) remote probe can be used with each 5821 wireless temperature and water sensor.
