FAQ ("Frequently Asked Question")

Q1: I've seen part numbers for the 6 zone controller as PFMZ-06-001 and PFMZ-06P-001. Are these different products? What the "P" stand for?
A1: Navien tech support has confirmed that they used both item number schema interchangeably in the past. Examples:
PFMZ-02-001, PFMZ-03-001, PFMZ-04-001 and PFMZ-06-001. However, as of 2018, they are using only the item numbers containing the P, and references to the item numbers without the P are no longer shown on Navien's resources. The manual refers to this item as FMZ.

Q2: Will this zone controller turn the zone pumps OFF if the Navien NHB boiler turns off when the outdoor temperature exceeds the preset point in the boiler? Right now I am using a generic controller, and when the boiler turns off because the outdoor temp is higher than what I have the boiler set at, then the zone pumps will continue to run even though the boiler is off.
A2: Yes, the SmartZone+ will turn zone pumps off in response to outdoor temperature sensor signals. That is one of the functions it is designed for.

Q3: Will this zone controller control zone valves?
A3: No. For that we recommend a Taco zone valve controller.

This zone pump controller works great with the navien boiler. One thing to note is that this doesnt come with the navi link cable (which it should in my opinion). They do that because this unit can be used interchangeably with other boilers, but still, for the money spent on this item, a cord should not make or break navien's bank.

Advantages: Works great for a navien boiler. Can be used to control a generic boiler with a boiler pump if needed.

Disadvantages: Doesnt come with the communication cable
