Caleffi hydronic zoning controls.

I often dread the call in the dead of the night at -20C, that someone somewhere has no heat. Problem, some zones were not heating sufficiently, or shut down completly resulting in a rather cool home. If you will notice the picture, of the knot of wiring, near the bottom of this article, you will notice the nightmare encountered in troubleshooting the no heat call. Hours of wire tracing was required in order to begin troubleshooting. The best option would have been to use a zone valve controller, offered by Caleffi products that would have been more suited for this situation.

We use a wide variety of Caleffi zone control equipment. Zone valves, actuators, radiant floor distribution manifolds and the Caleffi zone valve switching control.

Caleffi offers individual zone control actuators including standard zone valves. These zone valves come in numerous fitting options including solder, IP connections and now even Propress.

As shown, the connections are easily accessible, confirmation of thermostat and end switch communication.
Multiple pump outputs offer many pump switching options. And dedicated DHW and space heating temperatures.

Caleffi manufactures a composite plastic radiant floor manifold, shown on the left. It makes a heck of alot of common sense to utilize these quality Caleffi zoning products. Caleffi manufactures manifolds from brass or a composite plastic. Click here for more Caleffi radiant manifolds. There are numerous options available in radiant manifolds. They offer adjustment of the flow out of each zone including accurate flow indicators. Other options would include zone actuators for multi zone switching.   individual zone loop can be adjusted to match the zone flow needs.

Caleffi offers more out of the box usable hydronic equipment and components.

This nightmare junction box shown on the left is the most common method used to wire in zone valves or actuators. shows the knot of wiring that a boiler service technician may No, no, no this is not the industry best standard for zoning control. Imagine just having to unravel this knot of a mess to even begin troubleshooting.This just happens to be a boiler service technician worst nightmare. The new Caleffi ZVR series of zone switching control was the best solution with this particular situation.

Its would be simple common sense, would it not, if some form of zone switching control was used upon initial installation of the boiler system and controls. It is not common practice it seems for common sense to prevail. As was the case on this particular project.
