Product Highlights
Description
The VA33 spacer ring A3019900 is required for adapting A3023522 to older style Wirsbo Brass Manifolds.
Uponor is transition from 2 Red & 2 Yellow wires to 2 Yellow, (1) Black and 1 (White) Wire. Please follow the specific installation instructions based on which model actuator you receive
The Uponor Thermal Actuator is a slow-opening thermal actuator that provides individual loop flow control on a multi-zoned manifold and features an end switch for activation of relay (pump), heat plant or other auxiliary devices.
Uponor's new Thermal Actuator, four-wire features a new design with lower power consumption (1 watt) and includes three adapter rings for compatibility with all of Uponor's radiant manifolds, including:
- Engineered Polymer (EP) Heating Manifold
- Stainless-steel Manifold
- TruFLOW Jr. Manifold
- TruFLOW Classic Manifold

Pretty poor actuator -- they have two major problems
Perfect Replacement
Products came as expressed and delivered promptly.
Would buy again
Easy installation
Great Product
Good alternative
It Works! but watch that you power up device before trying
The actuators are good but the adaptor rings are hard to fit
I did buy this product 3 times and its great
I would buy again

Q: My A2870100 adaptor ring won't fit on wirsbo manifold (about 15 years old} Looks not to be deep enough. Trying to replace A3020522 motorized valve acuator with Upnor A3023522
Asked by wandug 11 years ago

Verified Reply- SupplyHouse StaffWhen connecting to a Wirsbo manifold, ring A3019900 must be purchased in addition to the actuator. The included rings are for the current model manifolds.
Q: color of wires. 2 red? 2 yellow. which is power and which is end switch?
Asked by gene 11 years ago

Verified Reply- SupplyHouse StaffThe red wires are the end switch .Yellow are to the system.
Q: Can this actuator be installed upside down?
Asked by norcal06 11 years ago
Add your answer
Verified Reply- Supplyhouse StaffNo, the manifolds themselves should be installed upright.
Q: installed the new actuators but some of them pop off the valve body, adapter ring threads on maybe 1/2 turn any insight?
Asked by NV 11 years ago
Add your answer
Verified Reply- Supplyhouse Staffyou may need the correct adapter ring for the actuator/manifold
If you have an older Uponor TrueFlow manifold, you also need a brass adapter ring (A2630028). Nowhere is this mentioned in the descriptions.
Q: I bought 2 thermo-actuators to replace 2 motorized actuators. Only one of the "old" motorized actuators is bad. Can I use one motorized and one new thermo-actuator that are controlled by different thermostats? (same aquastat )
Asked by ginger 12 years ago
Add your answer
Yes. Mechanically they work the same. Ron
Ginger, Yes, you can mix zone valve and actuator types on the same circuit, as long as they are all 24V and you check to make sure the total power draw of all actuators, relays, etc. does not exceed what your transformer can supply. The heat-actuated valves will operate much more slowly than the motorized ones. Tom Wills
Q: We are going to replace our Wirsbo motorized actuators. Do we need to buy the spacer rings? It looks like there is already a spacer ring under the old actuators but we haven't taken anything apart yet.
Asked by house whiff 12 years ago
Add your answer
Not sure what spacer rings you're referring to (perhaps wave washer?). But the ones I bought were complete. Just screw them on and hook up the wires. Good luck.
No spacer rings are required
No. I didn't need to buy a spacer ring when I replaced my actuators. Sent from my iPhone
All I bought was the actuators and they worked
I use this to simply replace the old unit...use everything in the box. My system only requires two wires, so I only use two of the four wires in this unit. --rd
Q: A310522 Valve Question: Is there a way to RESET the Valve like it was from the box? The furnace had to be turned OFF at the main power box while the Valves had the Manifold OPEN and the pumps ON when the furnace Igniter malfunctioned. The Valves did not return the Manifold to the CLOSED position at that time. When power was reapplied, the Valves did NOT move – stayed where they were. I turned the power back off and removed the Valves to see if they would return to their OFF position to no avail. Are they jammed / broken?
Asked by Keith 13 years ago

There are 2 types of actuators. One with a metal knob to adjust the valve and one with a plastic top that can't be adjusted. If you have the one with the metal knob it has to be adjusted to the open position when it's energized. If you screw the metal knob all the way down the manifold valves won't close. Hope this helps.
Q: We presently have Wirsbo Motorized Valve Actuator Part #2052382 & are wondering if this part will work it its place.
Asked by Don @ Adamanda 13 years ago

Don@Adamanda’s, I am a home owner who does his own maintenance on our residential Wirsbo system. The motorized and thermal actuators from Wirsbo are generally interchangeable. Functionally they are similar with the thermal actuators being slower to open and close than the motorized version. In my experience the thermal actuators have been a longer-life part than the motorized actuators. (Our system is seventeen years old and I have replaced all of our actuators with thermal actuators.) Good luck!
Q: Does this product have a warranty.
