5 Service

CAUTION: Requires a qualified service person because electrical shock hazard is present.

5.1 Circuit Breaker Trips

Check For Short In Wiring:

Turn off the 7-day timer by moving all the spades out. Turn off all the remote timers and the dehumidistat (if used). If the circuit breaker trips, locate a short in the wiring. If the circuit breaker does not trip, activate the 7-day timer. If the circuit breaker then trips, check the blower motor.

5.2 Blower Operates on One Speed Only

Operates On Low Speed Only:

If the blower operates only on low speed, deactivate the 7-day timer so that unit is not running. Activate one of the optional controls and then check for voltage to the relay coil (terminals 7 and 8). See Figure 4. If voltage is not present, check for a loose wire or a defective optional control. If voltage is present, check for voltage between relay terminal 4 and ground. If there is no voltage, the relay is defective. If there is voltage at terminal 4 and the motor does not operate, the high speed winding of the blower motor is defective. Replace the blower.

Operates On High Speed Only:

High speed operation of the blower has priority over low speed. Verify that all the optional controls are in the off position. If the blower operates on high speed constantly, check for voltage between relay terminals 7 and 8. If voltage is present, one of the optional controls is not opening and is defective.

If the blower operates only on high speed (when the optional controls are activated) and is off the rest of the time, check that the segments on the 7-day timer are moved to the center of the dial, thus calling for low speed ventilation. If the blower does not run with the segments in and the optional controls off, check for voltage between timer terminal 5 and ground. If terminal 5 does not have voltage, the timer is defective. If terminal 5 has voltage and relay terminal 5 does not have voltage, the relay is defective. If relay terminal 5 has voltage, the low speed winding of the blower motor is defective.

5.3 7-Day Timer Does Not Advance

Check for voltage between timer terminals 1 and 2. If voltage is present and the timer does not advance, the timer motor is defective and the timer must be replaced.

5.4 Fan Motor

If the blower motor fails to operate when voltage is present at its leads, the motor is defective and the blower must be replaced.

5.5 Warranty

The Quiet-Vent is guaranteed for two years from the date of installation against all manufacturing defects provided the Quiet-Vent has been installed, operated, and maintained as stated in this manual. This warranty is limited to the repair or replacement of the equipment, F.O.B. MADISON, WI. Call the factory at 1-800-533-7533.

Quiet-Vent Ventilation System specifications

The Therma-Stor Products Group Quiet-Vent Ventilation System represents a significant advancement in indoor air quality technology, specifically designed for residential and commercial applications. This innovative system addresses the growing demand for effective ventilation solutions that minimize noise while maximizing performance. With a focus on customer comfort, sustainability, and efficiency, the Quiet-Vent is a standout choice for those seeking to improve their indoor environments.

One of the main features of the Quiet-Vent Ventilation System is its whisper-quiet operation. This is achieved through advanced engineering and sound-dampening technologies that significantly reduce the noise associated with typical ventilation systems. Users can enjoy fresh, filtered air without the disruptive sounds that often accompany traditional systems, making it ideal for bedrooms, offices, and shared living spaces.

The system incorporates state-of-the-art filtration technologies that effectively capture airborne pollutants, allergens, and particulates. With high-efficiency particulate air (HEPA) filters, the Quiet-Vent ensures that the air being circulated is clean and healthy. This is particularly beneficial for households with allergy sufferers or those concerned about indoor air quality due to external pollutants.

Another noteworthy characteristic of the Quiet-Vent system is its energy efficiency. The design includes an energy recovery ventilator (ERV), which transfers heat and moisture between incoming and outgoing air streams. This process helps maintain balanced humidity levels while reducing energy consumption, translating into lower utility bills and a reduced environmental footprint.

The Quiet-Vent is also designed with user-friendly controls, making it easy to monitor and adjust settings to suit individual preferences. Optional smart technology integration allows for remote operation and scheduling, providing convenience for modern users who rely on automation and smart home devices.

Durability and reliability are critical components of the Quiet-Vent’s design. Built with high-quality materials, the system is engineered to withstand the test of time, requiring minimal maintenance. This feature ensures peace of mind for homeowners and business operators alike.

In conclusion, the Therma-Stor Products Group Quiet-Vent Ventilation System is a sophisticated solution for anyone looking to enhance their indoor air quality. With its quiet operation, advanced filtration technologies, energy efficiency features, user-friendly controls, and durable construction, it stands out as a top choice for effective ventilation without compromise. This system represents a significant leap forward in creating healthier, more comfortable indoor environments.
