If you need additional help or prefer to speak with a representative, our Service Department is always available to assist you directly.
My unit won't turn on or turned off overnight, what should I do?
First, verify that the circuit breaker is supplying the correct voltage to the unit. Then, check the SmartPad or HMI for any fault indicators. If the issue persists or a fault is present, please contact our service department for further assistance.
My unit is not controlling humidity?
Begin by verifying that the unit is cycling correctly. Also, check the water setpoint, the actual water level in the unit, and the water output. Additional factors that may affect humidity control include improper damper operation or an incorrectly adjusted float valve. If the issue persists after these checks, please contact our service department for further assistance.
My SmartPad says Ace not detected, what does this mean and what should I do?
Inspect the wiring connections between the SmartPad and the Ace Board to ensure they are secure. This issue may indicate a faulty Ace Board, which could require firmware reinstallation or full board replacement. If the problem continues, please contact our service department for further evaluation and support.
What can cause condensation to form inside the stability chamber?
Condensation inside the chamber is typically caused by high humidity. Begin by inspecting all penetrations and room seals to ensure they are properly sealed. Next, check the door heat settings, as an increase may be necessary. If condensation persists after these steps, please contact our service department for assistance.
Why is there an issue with the chamber’s alarms not triggering during temperature or humidity deviations?
This issue may be due to alarms not being enabled. It can also occur if the alarm thresholds are set too high or if the high/low limits have not been configured. If the issue remains unresolved after reviewing these settings, please contact our service department for further support.
Why is my stability chamber taking longer to stabilize the set conditions?
Start by verifying the setpoints to ensure both the air and water heaters are functioning correctly. Then, check the damper and blower to confirm they are operating as expected. Finally, inspect the ductwork for any potential leaks. If the issue continues, please contact our service department for assistance.
How do I check for refrigerant issues in my stability chamber, and what are the signs of a leak?
How can I address a failure to calibrate the chamber’s sensors error correctly?
A reference sensor is required to recalibrate the unit. To obtain one, please contact our service department to inquire about purchasing a new sensor. Parameter’s Service Department also offers a Calibration Exchange Program, which provides recalibrated sensors on an annual exchange basis.
What are recommended cleaning agents for my Air Handling System?
Parameter Generation & Control recommends using Rydlyme for cleaning, particularly on heavily soiled evaporator coils. If you prefer to use a different cleaning agent, please contact our service department for a list of approved cleaning agents.
What are the differences in alarms and faults for my unit?
Faults are designed to shut the unit down in order to protect major components from potential damage. Alarms will sound and display an issue, but the unit will continue to operate. It is important to verify that alarms are not set to trigger faults in the SmartPad or HMI settings.
