This setting prevents your furnace/boiler from short cycling, so we recommend leaving this at 300 seconds to prevent any potential damage to your equipment. The system controller must lock out the compressor if the thermistor temperature exceeds 260°F (127°C). This is set to 300 seconds (5 minutes) by default. When the OD temp is in between these two set points, the system operates normally with compressor and aux heat strips as needed. Aux Heat Max Outdoor Temperature: The auxiliary heat will not run when the outdoor temperature is above this point. If you choose to configure staging manually. Cooler air may have less moisture, but there is a limit to how cold you want your system to get. Get in touch with our support team. Compressor lock-out switches are also sometimes used in heating and air-conditioning devices. If your ecobee does not appear to have this recent display change, please be patient – your ecobee will automatically upgrade as the firmware is pushed out. 4 GENERAL INFORMATION WARNING: Improper installation, or installation not made in Loud noises when the compressor is running. If you choose to configure staging manually, you will be able to select and customize values such as dissipation time, temperature deltas, and runtimes for both your heating and cooling equipment. Compressor replaced yesterday. Because water expands as it freezes, ice can also crack system components. NOTE: During "Away" periods or Custom Comfort Settings set to "I'm Usually Away", an additional 1°F/0.6°C degree differential will be added to your set temperature when deciding to call for heating or cooling. This is set to auto by default. 1-Hour Pickup! This is set to auto by default. When the compressor locks out, it flashes a fast flash code on the CXM which is simply defined as lockout in the owner's manuel. Heat Differential Temperature: The minimum temperature differential before engaging heat. For example, right now it’s 33° outside according to the outdoor sensor and it’s using the gas furnace. To access the THRESHOLDS menu on the thermostat: MAIN MENU > SETTINGS > INSTALLATION SETTINGS > THRESHOLDS. Compressor to Aux Runtime: The minimum number of minutes the compressor will run for before switching to auxiliary heat. Heat/Cool Minimum Delta: The minimum temperature difference between the desired Heat and Cool set points in Auto mode. We can help you design a compressed air system that will withstand your environmental conditions. But on the Nest Thermostat itself, the term "Lockout" is not used, instead you see " Use the heat pump compressor when the outdoor temperature is above ". List Price: $ 93.18. Before adjusting this setting, we recommend reaching out to the manufacturer of your heat pump/compressor to inquire about the safest setting. Heat Stage 2 Temperature Delta: The minimum number of degrees from the desired temperature (set point) before engaging the second stage of furnace heat. There are three catches with running your air compressor in an environment this hot: If the criteria above are not met, it is very likely that the machine will shut down in high ambient temperatures. Refrigerant has been added (2 gal). Maintaining ambient temperatures of 85°F or below will reduce the risk of shut down due to overheating. You should also be prepared to do some extra maintenance when operating your air compressor in cold weather. Page 24 Heat Pump: Both auxiliary and compressor lockout temperatures can be changed in the Heat Pump section of the Advanced Settings menu. I have a vision pro tstat with temp sensor outside. Premium quality fully synthetic oil must be used. Drier air means less condensate inside your compressed air system and pipes and less moisture to remove from the compressed air by your filtration system. Air compressor overheating is one of the most common causes of system failure. Two hard start capacitors have been replaced. 82 thermal Lockout in high stage. COMPRESSOR LOCK OUT SWITCH.
