Why is the MTA TAEevo015 tank water outlet temperature higher than expected?
- B
  Benjamin TuckerAug 18, 2025
  The tank water outlet temperature (BTWOT) in your MTA Chiller might be higher than expected due to several reasons. It could be that the thermal load is too high, in which case you should restore it to the preset limits. Alternatively, the ambient temperature might be too high; if the unit is in a closed space, try increasing the airflow to lower the ambient temperature. Also, check if the condenser fins are dirty and clean them if necessary. Make sure the front surface of the condenser isn't obstructed. A lack of refrigerant or compressor protection trips could also cause this issue; in these cases, get a technician to check for leaks and refill the system.

What to do if the high pressure switch tripped (HP) on my MTA TAEevo015 Chiller?
- Z
  Zachary RodriguezAug 21, 2025
  If the high pressure switch on your MTA Chiller has tripped, it could be due to several reasons. First, check if the fan is working; if not, repair or replace it. Also, high ambient air temperature can cause this, so ensure adequate ventilation. Recirculation of warm air due to incorrect installation can also be a factor; reposition the unit to avoid this. Dirty condenser fins or an obstructed condenser surface can also cause the high pressure switch to trip, so clean them if necessary. Finally, a thermal load that is too high can also cause the issue; reduce the load if possible.

What causes compressor protection trips on the MTA TAEevo015?
- W
  wcastilloAug 23, 2025
  Compressor protection trips on your MTA Chiller, indicated by alarm A09 or A10, can occur due to a high thermal load combined with a shortage of refrigerant. In this case, it's best to call a qualified refrigeration engineer to check for leaks and replenish the refrigerant. For three-phase units, an incorrect rotation direction of the scroll compressor can also cause this issue; if this is the case, invert two phases of the power supply.

Why is the low pressure switch tripping on my MTA TAEevo015 Chiller (Alarm A02)?
- Z
  zacharyscottAug 26, 2025
  If the low pressure switch is tripping on your MTA Chiller, indicated by alarm A02, it could be due to a lack of refrigerant. In this case, it's recommended to call a qualified refrigeration engineer to check for leaks and replenish the refrigerant charge. Another possible cause is a dirty filter upstream from the unit. If a filter is installed, try cleaning or replacing it.

How to fix a water differential pressure switch FLOW alarm (A08) on an MTA TAEevo015?
- J
  Justin MartinezAug 28, 2025
  A water differential pressure switch FLOW alarm (A08) on your MTA Chiller can be triggered by several issues. If a filter is installed upstream from the unit, it might be obstructed and needs cleaning. Also, the pump could be defective or rotating in the wrong direction (for three-phase supplies); check the pump's electrical supply and invert two phases if necessary. Another possibility is that the water inlet and outlet are inverted (for units without a hydraulic kit); if this is the case, invert them.

Why is there low water pressure at the pump outlet of my MTA TAEevo015 Chiller?
- C
  Christina ShawAug 31, 2025
  A low pressure drop (water pressure) at the pump outlet of your MTA Chiller can be caused by a water flow that is too high, indicating incorrect pump operation. Reduce the water flow to within the preset limits, for example, by partially closing a pump outlet cock. Reset the pump thermal protection and check the electrical absorption. The evaporator may also be obstructed due to dirt transported by the water. Depending on the type of dirt, clean the evaporator by running a detergent solution (that is not aggressive for steel, aluminum, and copper) or run a high water flow against the stream. Consider installing a filter upstream from the unit to prevent future issues.

What causes the A08 pump thermal protection alarm on my MTA TAEevo015?
- A
  Austin SchwartzSep 2, 2025
  The A08 pump thermal protection alarm on your MTA Chiller indicates that the pump's thermal protection device has tripped. This can happen if the water flow is too high; try resetting the thermal protection device and increasing the pressure drop in the hydraulic circuit, perhaps by partially closing the pump output valve. Another cause could be an obstructed grille through which the pump cooling air passes; reset the thermal protection device and free the grille. The pump itself could also be defective; in this case, reset the thermal protection device and replace the pump.

What should I do if the digital display and LEDs are off on my MTA TAEevo015?
- M
  Mary GonzalezSep 5, 2025
  If the digital display and all LEDs are off on your MTA Chiller, even though the main switch is on, the auxiliary circuit fuse may have tripped. Check the causes of the fuse tripping and replace the fuse. It could also be due to abnormal power consumption by one or more of the control board components. Try turning the unit off and on again. If this doesn't solve the problem, contact the nearest service center.

What does alarm A04 mean on my MTA Chiller and how do I fix it?
- R
  robin33Sep 7, 2025
  Alarm A04 on your MTA Chiller indicates a low water outlet temperature. This can happen if the value set by the parameter is lower than the temperature measured by the probe. Identify and remove the cause that provoked the BTWOT temperature decreasing to a value lower than Ar03. It can also be caused by too low water flow. Increase the water flow to resolve this.

What does it mean if my MTA Chiller displays alarm P1, P2, P3, or P4?
- A
  Alicia FosterSep 9, 2025
  If your MTA Chiller displays alarm P1, P2, P3, or P4, it indicates that the probe BEWOT, BTWOT, or BAT1 is damaged. Check that the temperature probe is correctly connected to the control board terminals and that the cable is undamaged. If necessary, replace the probe.
