Thanks. Found the one that will work for my application. Also, would you mind sharing a more detailed look at your final wiring at the control board?
I couldnāt find a more detailed photo in my library. Any particular part you were interested in? I can try to take some photos later tomorrow.
On Kensblog.com Equipment - Welcome to KensBlog he describes his kabola interface with his chilled water system. Specifically he has this diagram https://www.kensblog.com/wp-content/uploads/2019/12/tempered_water_interface_gb-70-1.jpg.
You can see that instead of putting the boiler directly in the main tempered water loop it has a separate loop that heats the main loop via heat exchanger.
Thatās a pretty typical hydronic install. The Chinook has a separate heat exchanger built into it to do just this, separated from the one that does the hydronic side.
Sorry, missed your response. Might have to look to see if thereās a notification setting for the messages. Anyway, just looking to do a clean install and I liked how you have the control panel and wiring set up. Iām running the supply lines right now and hope to set the heater in place soon so Iām measuring out distances and layouts for the best options. Any additional pics might be helpful and would be appreciated. Thanks.
Hi Phil,
I havenāt been back to the boat since the last message, and am trying to bring the new boat back home, so I might not get a picture for at least another week.
Notification settings can be found by clicking your picture icon in the upper right, clicking on the person icon, then Preferences, then Emails. By default I think it sends you email if someone replies to one of your messages directly, but you might have been able to turn that off when signing up.
Sounds good. The new boat looks nice, BTW. Looking forward to your future write ups on it.

Iām at the point where Iām running the wiring for the thermostats. However, the wiring diagram is a little confusing and Iām trying to figure out how to wire them up. The manual lists each zone as a colored lead but doesnāt say how the lead is wired to the thermostat or whether or not they should be fused. Any help you might offer on this would be appreciated. Thanks
I wasnāt able to take any further photos before the boat went to the new owners, unfortunately.
Page 6-5 of the Hurricane Chinook installation manual talks about the wiring for the thermostats. You need a 12v DC source that has a 1 amp fuse going to the thermostat. The return from the thermostat then goes to the appropriate zone wire for that particular zone.
Many heaters are set up this way where the thermostat energizes a 12v circuit back to the zone board or control system to indicate when heat is required.
I think I was just overthinking it. That makes perfect sense now that I run it through my head. For some reason I was thinking that the thermostat had to be grounded as well. But, hey, one less wire to pull is great news in my book. I canāt believe how much wire Iāve already run for this project. Iām just happy that Fisheries is a pretty simple ferry ride awayā¦ā¦

Hi Steve. Iām just finishing up the details on my install and Iām not at all happy with the cheap thermostats. I picked up one of the Aube thermostats that you installed but Iām confused to how that one is wired up. Any chance you could help me out with how to get it working?
Thanks
Hmmmm I donāt know that there would be any different wiring for the Aube than the standard ones that everyone uses. Itās essentially two wires, one positive (with the fuse that I had taken a picture of in the article) coming in to the thermostat, and a return going back to the zone that you want to activate. The Aube also require batteries, but most of them do that arenāt the super old mercury ones.
Thatās what I was thinking so maybe Iāve got a bad one. It wonāt call for heat and doesnāt allow me to change the temperature after I put the cover back on the unit. Iāll pick up another one and see if I run into the same issue. My other thermostats all work. The only problem Iām running into now is that zones 3 and 4 wonāt kick on the circulating pump unless zone 1 or 2 is actively calling for heat. Iāve set the jumper as per the instructions but still not having any luck. When those zones call for heat I get the green lights on the control board and voltage out to the fans but the loop isnāt circulating. Waiting on a call back from ITR to see if they have a solution.

Do you hear a click and see the little wavy lines on the display when the thermostat calls for heat? Make sure you are connecting the wires to the covered contact points under the top center portion of the thermostat. I saw someone connect the wires to the telephone / remote activation contact points which wonāt work.
There is no indication at all that itās calling for heat. Iām confident that itās wired correctly and Iāve checked it with one of the analog thermostats. Works fine that way. Iām pretty confident now that itās a bad unit. I have another one on the way that Iāll try out.

Quick question. Our unit has an automatic summer loop (thereās no physical valve) and weāve noticed when we run the water that the main cabin fan turns off. Does the same thing happen with your unit?
I ended up selling Rendezvous in December of 2021 which is where my Hurricane unit was installed, but I do not remember the main cabin fan going off when I ran the water at all. I used the water heating function all the time in the unitā¦
Wow, what an excellent post. I have a question regarding the āSummer Valveā and how it bypasses the heating fans. I assum that you have to close the loops going to the fans and then open the summer valve. My question that that will bypass the expansion tank! Do you not need the expansion tank in the summer loop?
Hi @Derick_Clack,
The summer loop is automatic with this system. You donāt have to close any valves or loops going to other places. Most of the other hydronic systems Iāve worked on or had on my own boats, including the one I have on Aruna, have manual valves that you have to close to the various loops to prevent circulating the coolant around the boat in the summer.
There is no expansion tank in this system. It is essentially built into the main unit, so you donāt have to do anything with the summer loop regarding the expansion tank.
Hi Steve. Thanks for responding so quickly. So my question is what is the summer valve in the picture for? How does the water not circulate to the the rest of the boat during summer?
