Most compressor manufacturers engineer their machine for a maximum of 105°F, which is the max rating of the motor insulation. This is set to 5⁰F/2.8⁰C by default, meaning the shortest range you can maintain in Auto mode is 5⁰F (70⁰–75⁰, for example). 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. Compressor Reverse Staging: With this setting enabled, you will also need to enable the Compressor Stage 2 Temperature Delta threshold setting listed above and set a temperature value. There is now the option to have the staging configured as Automatic or Manual. Compressor Minimum Outdoor Temperature: The compressor will not run below this outdoor temperature. Compressor to Aux Runtime: The minimum number of minutes the compressor will run for before switching to auxiliary heat. By default, Nest will lock out the Setting compressor and auxiliary heater when the outdoor temperature is above 50°F but will not lock out auxiliary lockout temperatures the compressor at any temperature. If you’re receiving many “Aux heat running” alerts, you may want to adjust this setting (after confirming with your heat pump manufacturer the lowest temperature your heat pump can safely function at). 1-Hour Pickup! Before adjusting this setting, we recommend reaching out to the manufacturer of your heat pump/compressor to inquire about the safest setting.

Check the oil levels and change compressor oil on a regular basis. Two hard start capacitors have been replaced. This means that if the ambient temperature is 85°F, the incoming air from the compressor to the dryer will be 100°F at full load. But how hot is too hot, and how cold is too cold? 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. In this case, you will need to bring the ambient temperature around the air compressor up to 45°F before restarting it. Threshold settings allow you to configure your HVAC equipment for greater efficiency and prevent damage to your equipment by controlling how the ecobee engages it. This mode is most useful if you live in a region where the temperature fluctuates regularly or you’re in the middle of a season change and you may need both heating and cooling at different times during the day. This is set to 0.5⁰F/0.3⁰C by default. Learn more: Can you use your air compressor in cold weather? Your ecobee will ignore this inaccurate reading to prevent your heating or cooling from running excessively. Aux Reverse Staging: With this setting enabled, you will also need to enable the Aux Heat Stage 2 Temperature Delta threshold setting listed above and set a temperature value. The system controller must lock out the compressor if the thermistor temperature exceeds 260°F (127°C). This is set to auto by default. Hot weather brings its own challenges for your compressed air system. This setting prevents your compressor from short cycling, so we recommend leaving this at 300 seconds to prevent any potential damage to your compressor. Usually when the outside temperature is above 30° it uses heat pump only but when it’s close to 30° it uses the back up gas furnace. Compressor replaced yesterday. Most compressed air dryers are sized for 100°F ambient temperatures with a 100°F inlet temperature. As with the low pressure cutout, the discharge temperature protection should have a manual reset feature for the highest level of protection. email@example.com. Learn more…. Humidity Correction: If you notice that the ecobee’s humidity sensor may be slightly off, you can adjust this + or – 10 % for a more accurate reading. If you notice your fan may be running longer than you’d like once a call for heat is finished, you can adjust this value. Loud noises when the compressor is running. Furthermore, when a compressor is fired up from a cold start, the oil is thick. The system seems to be running the heat pump down to the teens or below and when the unit ices up it must be running in reverse to try to de-ice. This is set to auto by default. If you’re receiving many “Aux heat running alerts,” you may want to lower this setting—this will maximize the use of your heat pump while limiting the use your aux heat. The oil sump tank must be filled to its maximum level.

Premium quality fully synthetic oil must be used. The ecobee will run the second stage of your aux heat if the current temperature is greater than the value designated in the Aux Heat Stage 2 Temperature Delta setting. Maintaining ambient temperatures of 85°F or below will reduce the risk of shut down due to overheating. Check ductwork for blockages, punctures, or debris buildup and clean vents and ductwork on a regular basis. When the OD temp is in between these two set points, the system operates normally with compressor and aux heat strips as needed. Enter the keypad lockout code by pressing the up or down arrow button until your combination number appears on the screen. If possible, control the ambient temperature in your air compressor room to maintain temperatures at 85°F or below. COVID-19 Update: Fluid-Aire Dynamics is here for you, 24/7/365, and even during this pandemic. Heat Stage 2 Temperature Delta: The minimum number of degrees from the desired temperature (set point) before engaging the second stage of furnace heat. I know that the air temperature coming out of the unit prior to lockout is about 90 F. Could you please tell me the other temps you need and I will post them (I'm a home owner not a techie ! The keypad lockout code is created when the thermostat is installed. This is why we say 85°F is the ideal maximum temperature. In a low temperature situation , the low pressure switch will tr ansition open afte r the compressor starts. Keeping temperatures with the 50 – 85°F range will also help your system run at maximum efficiency. Heat pump compressor lockout temperature? Need assistance? This damage can be very expensive to repair. Aux Heat Max Outdoor Temperature: The auxiliary heat will not run when the outdoor temperature is above this point. Refrigerant has been added (2 gal). Your ecobee will look at your 'Savings vs Comfort' setting to control your equipment staging. Low Entering Condenser Water Tem-perature When the entering water temperature sensor reads a water temperature below the minimum water temperature input into the controller. If you choose to configure staging manually. You can program it for compressor lockout below a certain OD temp and run only the aux heat strips. Keep oil cooler coils (and all system components) clean. This firmware version makes minor adjustments to the thresholds menu. d. NOTE- If no outdoor sensor is installed or enabled, lockouts will be displayed as OFF and are not adjustable. The compressor lock-out relay can operate only when the thermostat is set in the cooling mode. With this extreme cold, however, I've hit a problem.
