Why is the Rehsler Kuhlsysteme Chiller tank water outlet temperature too high?
- K
  Kristin WilcoxAug 18, 2025
  The tank water outlet temperature might be higher than expected due to several reasons: * The thermal load might be too high. Try restoring the thermal load to within the preset limits. * The ambient temperature may be too high. If installed in a closed space, increase the air flow to lower the ambient temperature. * The condenser fins could be dirty. Clean the condenser fins. * The front surface of the condenser might be obstructed. Clear any obstructions. * There might be a refrigerant leak. In this case, a technician should check for leaks, eliminate them, and refill the unit. * The compressor protection may be tripping. If so, a technician should check for leaks, eliminate them, and refill the unit.

What to do if Rehsler Kuhlsysteme TAE K20 displays high pressure switch tripped (HP) Alarm A01?
- J

  If the high pressure switch has tripped and Alarm A01 is displayed, consider the following possible causes: * The fan might not be working. Repair or replace the fan and verify its heat protection. * The ambient air temperature could be too high. Reduce the ambient temperature by increasing local ventilation. * Warm air might be recirculating due to incorrect installation. Change the unit's position or remove obstructions to prevent recirculation. * The condenser fins could be dirty. Clean the condenser fins. * The front surface of the condenser might be obstructed. Clean the front surface of the condenser. * The thermal load might be too high. Reduce the thermal load if possible.

What to do if Rehsler Kuhlsysteme TAE K20 Chiller compressor protection trips and Alarm A09 or A10 appears?
- K
  Kenneth RamirezAug 22, 2025
  If the compressor protection trips and Alarm A09 or A10 is displayed, it could be due to: * A thermal load that is too high combined with a shortage of refrigerant. In this case, call a qualified refrigeration engineer to check for leaks and replenish refrigerant charge. * The rotation direction of the scroll compressor being wrong (only on three-phase units). If so, invert two phases of the power supply.

What to do if Rehsler Kuhlsysteme TAE K20 Chiller displays Water differential pressure switch FLOW alarm A08?
- B
  bevansAug 26, 2025
  If the water differential pressure switch FLOW alarm trips and A08 is displayed, check the following: * If installed, the filter upstream from the unit may be obstructed. Clean the upstream filter. * The pump might be defective or rotating in the wrong direction (for three-phase supplies). Check the pump's electrical supply and, if necessary, invert two phases. * If the unit lacks a hydraulic kit, the water inlet and outlet might be inverted. Invert the water inlet and outlet.

How to fix low pressure drop at pump outlet in Rehsler Kuhlsysteme Chiller?
- R
  Richard SmithAug 27, 2025
  A low pressure drop (water pressure) at the pump outlet may be caused by: * Water flow being too high or the pump working incorrectly (high flow, low discharge head, high absorption). Reduce 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 being obstructed by dirt transported by the utilization water. Depending on the type of dirt, clean the evaporator by running a detergent solution which 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.

What to do if Rehsler Kuhlsysteme TAE K20 Chiller displays low pressure switch tripped (LP) Alarm A02?
- A
  Angela CarrAug 30, 2025
  If the low pressure switch has tripped and Alarm A02 is displayed, the possible causes are: * Lack of refrigerant. Call a qualified refrigeration engineer to check for leaks and replenish the refrigerant charge. * The filter upstream from the unit is dirty, if installed. Clean or replace the water inlet filter, if installed.

What causes the Rehsler Kuhlsysteme TAE K20 Chiller digital display and LEDs to turn off?
- C
  Cody JonesSep 2, 2025
  If the digital display and all LEDs are off on your Rehsler Kuhlsysteme Chiller, even when the main switch is on, it could be due to: * The auxiliary circuit fuse tripping. Check the causes of the fuse tripping and replace the fuse. * 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 to do if Rehsler Kuhlsysteme Chiller shows Alarm P1, P2, P3, P4?
- D
  Devin GilmoreSep 4, 2025
  If Alarm P1, P2, P3, or P4 is displayed on your Rehsler Kuhlsysteme Chiller, it indicates that the BEWOT, BTWOT, or BAT1 probe 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.

How to resolve the Rehsler Kuhlsysteme TAE K20 Chiller Alarm A08 pump thermal protection?
- S
  Stephanie HullSep 6, 2025
  If the Rehsler Kuhlsysteme Chiller shows Alarm A08 for pump thermal protection, it may be due to: * The pump's thermal protection device tripping because the water flow is too high. Reset the thermal protection device and increase the pressure drop in the hydraulic circuit, for example, by partially closing the pump output valve. * The grille through which the pump cooling air passes being obstructed. Reset the thermal protection device and free the grille. * The pump being defective. Reset the thermal protection device and replace the pump.

What causes Alarm A04 on Rehsler Kuhlsysteme TAE K20 Chiller and how to fix it?
- M
  Mr. Benjamin Phillips MDSep 9, 2025
  If your Rehsler Kuhlsysteme Chiller displays Alarm A04, it indicates a low water outlet temperature. This can be due to: * The value fixed by the parameter is lower than the one measured by the probe. Identify and remove the cause which provoked BTWOT temperature decreasing to a value lower than Ar03. * Too low water flow. Increase the water flow.
