What to do if the Price Control Unit actuator does not operate for Variable Volume Valves?
If the actuator isn't working, check these items: * Confirm that power is being delivered to the unit. * Verify the control signal. * Ensure the disconnect switch (if equipped) is not open. * Check if the fuse (if equipped) is blown. * Make sure there are no obstructions in the ductwork.
What to do if the Price Control Unit heat cycles on and off?
If the heat is cycling on and off, consider these possibilities: * **Automatic Temperature Limit-Switch:** Increase airflow to allow coils to cool faster; the switch will automatically reset. Also, check to see if airflow to coils is unobstructed. * **Manual Temperature Limit- Switch:** Use the metal reset tab (if applicable) and press it toward the switch to contact and reset it. Airflow should be increased, and check to see if airflow to coils is free.
What to do if pressure is in alarm on Price Control Unit module, but airflow is present?
If the pressure alarm is active but airflow exists, take these steps: * Measure static pressure across the valve on available brass tees to confirm the pressure reading. * Ensure that red tubing runs from the valve inlet to the high (red) port and the green tubing runs from the valve discharge to the low (green) port. * Verify that the valve is installed in the correct airflow direction. * Ensure the tubing is not clogged with liquid or foreign debris.
What to do if actual airflow does not match airflow feedback in Price Control Unit?
If the actual airflow doesn't match the feedback, check the following: * Confirm static pressure is within the specified range. * Confirm that there is no blockage inside the duct or valve. * Confirm that there is no damage to any tamper proof paint. * Verify that there are no ductwork leaks before or after the valve. * Verify that the valve is installed in the correct orientation and airflow direction.
What to do if my Price Control Unit has no heat?
If your unit isn't producing heat, consider the following: * **Disconnection Switch:** Check to see if the door interlock is active. * **Fuses:** Use a Digital Multimeter (DMM) to measure resistance (R) of each fuse; it should read a negligible amount. If R is in MΩ, the fuse is likely blown. Order a new fuse from the replacement list. * **Wiring:** De-energize the panel and trace wires with the wiring diagram to check for loose, broken, or burned wires. * **Transformers:** With primary voltage active, use a digital multimeter to measure the secondary: it should be 24V ± 2V. If not in this range, replace the transformer. * **Automatic Temperature Limit-Switch:** Increase airflow to allow coils to cool faster; the switch will automatically reset. * **Manual Temperature Limit- S...
