How to troubleshoot a DriSteem Vapor-Logic with no green power light?
- R
  Robert MartinSep 4, 2025
  If the green power indicator light on your DriSteem Control Systems is off, check for proper supply voltage to ensure there is control voltage. If voltage is absent, inspect the heater fuses for any opens and check for voltage present at the transformer. Also, verify if the transformer secondary circuit breaker has tripped, check for any wiring shorts, and reset the breaker.

How to fix a DriSteem Vapor-Logic Control Systems keypad/display that doesn't energize?
- R
  Rebecca GarciaSep 2, 2025
  If the keypad/display on your DriSteem Control Systems does not energize, begin by checking the main fuse, main line safety switches, and heater fuses to ensure supply voltage to the unit is present. Next, verify that there is a proper 24 VAC supply, checking the transformer voltage characteristics and wiring. If voltage is absent, inspect the transformer circuit breaker and reset if needed. Also, check if the humidifier over-temperature thermostat is open and reset the manual switch located above the heater below the terminal cover.

Why is my DriSteem Control Systems unit not performing automatic drain?
- J
  Jennifer Cummings MDSep 1, 2025
  If your DriSteem Control Systems unit is not performing the automatic drain sequence, first verify that your humidifier is equipped with an automatic drain system and that it is enabled in the Setup menu. Then, check for a drain fault, a plugged drain valve, or a plugged drain pipe, and clean the drain valve piping if necessary. If the automatic drain sequence is malfunctioning, review the auto drain/flush settings in the Setup menu. Ensure that 24 VAC is present at terminal block P17 (drain) and at the drain valve. If voltage is present but the valve does not open, the automatic drain valve may be defective and require replacement.

What to do if there is no remote fault indication on DriSteem Vapor-Logic?
- G
  George QuinnAug 27, 2025
  If there is no remote fault indication on your DriSteem Control Systems, there are a few things to check: 1. Ensure that field wiring is installed to a remote fault indicator from the VAPOR-LOGIC terminal block J7. 2. Check if the field-supplied remote fault indicator lamp is burned out and replace if necessary. 3. Verify relay continuity (VAPOR-LOGIC terminal J7) for contact closure, as the remote fault VAPOR-LOGIC relay may not be switching.

What does it mean when the VAPOR-LOGIC red indicator light is on continuously on DriSteem Control Systems?
- J
  Joy AlvaradoAug 27, 2025
  If the VAPOR-LOGIC red indicator light is continuously on for DriSteem Control Systems, it may be due to a disruption in the VAPOR-LOGIC microprocessor. Verify proper control cabinet wiring and press the "RESET" button to reset the VAPOR-LOGIC control board.

Why can't I enter new parameters into the microprocessor through the keypad on DriSteem Vapor-Logic?
- F
  Frederick HollowayAug 26, 2025
  If you cannot enter new parameters into the microprocessor through the keypad on your DriSteem Control Systems, ensure that the digital display is not in "AUTO" or main menu format. Press the "MODE" key to enter the main menu, and then press the "ENT" key to access data in the selected main menu item. If new parameters are out of range, press the "CLR" key to start over and enter parameters within the acceptable range.

How to troubleshoot a VAPOR-LOGIC red indicator light that is off on DriSteem Control Systems?
- N
  Nicole SotoAug 25, 2025
  If the VAPOR-LOGIC red indicator light is off on your DriSteem Control Systems, it could be due to several reasons: * First, check for proper supply voltage. * Second, inspect the heater fuses for voltage at the transformer. * Third, see if the transformer secondary circuit breaker has tripped; if so, check for wiring shorts and reset the breaker. * Finally, verify proper control cabinet wiring and try pressing the "RESET" button to reset the VAPOR-LOGIC control board in case of a microprocessor logic disruption.
