Product Overview
In Carrier's ComfortID system the 33ZCSECTRM is the secondary controller. It works with a primary 33ZCFANTRM VAV fan terminal zone controller, running a second terminal so one zone can be pressurized with a paired exhaust or return terminal, or run as dual duct with a paired secondary terminal. Each arrangement needs its own secondary damper and airflow sensor. It ships with a Carrier-labeled Belimo damper actuator.

Frequently Asked Questions
Does it work without a primary controller?
No. It is a secondary controller and needs a primary ComfortID zone controller on the same zone.
Is the actuator included?
Yes. The Carrier 907-990050-4 actuator built by Belimo comes with it.
Is there paperwork?
The Carrier mounting instructions sheet is included.
Is this the secondary controller or the fan terminal controller?
The secondary. The controller label and the box label both read 33ZCSECTRM, and it has never been installed. The fan terminal controller it pairs with is 33ZCFANTRM. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Some zones need a second opinion on airflow, and this is the controller Carrier built to give it. Pair it with its primary and let the room hold its pressure.
