How to fix a Carrier Chiller controller that doesn't reset during the balance procedure?
If the Carrier Chiller controller doesn't reset to the maximum or minimum set point during the balance procedure, the balancer might be using the thermostat for the control signal. In this case, provide an artificial signal instead of the thermostat's signal.
Why does the air valve stay in the wide open position on my Carrier Chiller?
If the air valve on your Carrier Chiller remains in the wide-open position, it might be due to a blocked velocity probe caused by an obstruction or insufficient supply air in the inlet duct.
What to do if the air valve stays in wide open position in Carrier 35E?
If the Carrier Heating System's air valve remains wide open, it might be due to a blocked velocity probe. Check for obstructions such as a sandwich bag. Another possible cause is insufficient supply air in the inlet duct.
Why pneumatic actuator does not stroke fully in Carrier 35E Heating System?
If the pneumatic actuator in your Carrier Heating System doesn't stroke fully, there could be a leak in the pneumatic line between the controller and the actuator, or the main air pressure at the controller might be less than 15 psi. Also, check for a leak in the diaphragm.
What to do if the controller does not reset to maximum or minimum set point during operation in Carrier 35E Heating System?
If the controller in your Carrier Heating System doesn't reset to the maximum or minimum set point during operation, it could be due to the thermostat not demanding maximum or minimum air volume or the main air pressure at the controller being less than 15 psi.
How to fix controller that does not reset to maximum or minimum set point during balance procedure in Carrier 35E Heating System?
If the controller doesn't reset to the maximum or minimum set point during the balance procedure for your Carrier Heating System, it's likely because the balancer is using the thermostat for the control signal. To resolve this, an artificial signal must be provided in place of the thermostat.
What to do if the pneumatic actuator doesn't stroke fully on my Carrier Touch terminal?
If the pneumatic actuator on your Carrier Touch terminal isn't stroking fully, there could be a leak in the pneumatic line between the controller and the actuator. In this case, the main air pressure at the controller might be less than 15 psi. Another potential cause is a leak in the diaphragm.
Why does the air valve stay in the wide open position on my Carrier Touch terminal?
If the air valve on your Carrier Touch terminal remains in a wide open position, it might be due to a blocked velocity probe caused by an obstruction, such as a sandwich bag. Another potential reason is insufficient supply air in the inlet duct.
