Why is the air flow low in my Reversomatic Heating System?
- S
  Stacy GonzalezAug 12, 2025
  Low air flow in your Reversomatic Heating System can stem from several causes: an improperly balanced HRV/ERV airflow (if your unit lacks built-in automatic electronic air-balancing), a clogged filter, an obstructed core, a blocked exterior fresh air supply, ductwork restrictions, or a low power supply. To resolve this, have a professional balance the unit, clean or replace the filter, clean the core, clear any blockage in the fresh air supply, inspect the duct installation, or have an electrician check the voltage if you suspect a low power supply.

What to do if my Reversomatic Heating System's wall mount shows error codes E1, E2, E3, E4, or E5?
- A
  abbottdevinAug 16, 2025
  Error codes E1, E2, E3, E4, and E5 on your Reversomatic Heating System wall mount indicate various issues. These include loss of communication with the control board, defrosting temperature sensor failure, airflow sensor failure or humidity sensor failure. Check the wall control connections. For error code E2, clean the temperature sensor; if the error persists, replace it. For error code E3, clean the airflow sensors and reinstall them; if the error continues, replace the airflow sensors. For humidity sensor failure replace humidity sensor. Also check for kinked ducts and heavy dust build-up on airflow sensors. Finally, a fan failure may be the cause, requiring replacement of the intake or exhaust fan.

What to do if I sense cold air from the supply of my Reversomatic Heating System?
- S
  Sean BrownAug 20, 2025
  If you're sensing cold air from the supply in your Reversomatic Heating System, it could be due to a blocked exhaust hood outside the house, an improperly balanced HRV/ERV airflow (for units without built-in Automatic Electronic Air-balancing), furniture or closed doors restricting air movement, or extremely cold outdoor temperatures. Clear any blockage from the exhaust hood, have a professional balance the unit, or install a duct heater to address the issue.

Why is there water in the bottom of my Reversomatic HRV Heating System?
- J
  Janice MackAug 23, 2025
  Water accumulation at the bottom of your Reversomatic HRV Heating System can be attributed to clogged drain pans, drain tube, drain pipe, and/or the P-trap, or check connections. Inspect these components for blockages and kinks, and ensure that water drains properly.

What to do if the defrost mode doesn't work on my Reversomatic Heating System?
- S
  Scott HarperAug 27, 2025
  If the defrost mode isn't functioning on your Reversomatic Heating System, the fresh air duct might be frozen, the HRV/ERV airflow could be improperly balanced (for units without built-in Automatic Electronic Air-balancing), the defrost damper motor might be defective, or the temperature sensor may be faulty, or improper defrost cycle. Remove any ice from the fresh air duct, have a professional balance the unit, replace the defrost motor or the temperature sensor, or check defrost cycle on wall control and reprogram.

Why are all 3 LEDs of the timer switch blinking on my Reversomatic Heating System?
- P
  Patrick ArnoldAug 31, 2025
  If all three LEDs on your Reversomatic Heating System's timer switch are blinking, it indicates that the control board is reporting an error or there's a lost communication with main control board. Check all wire connections on the timer switch and main control board.

What to do if the timer switch 20/40/60 minute light doesn't stay on in my Reversomatic Heating System?
- A
  Amanda ThomasSep 4, 2025
  If the 20/40/60 minute light on your Reversomatic Heating System timer switch doesn't stay on, it could be due to a loose connection or a defective switch. Check the connection and, if necessary, replace the timer switch.

What to do if there is no display on the wall control of my Reversomatic Heating System?
- D
  Donna EvansSep 8, 2025
  If there's no display on your Reversomatic Heating System's wall control, the wires might be damaged or there could be a loose connection. Check the continuity of the wires and replace them if necessary. Also, check the connections on both the main controller and the wall controller.
