Question I had was is there a list off all the codes? I checked the control suppliment and they dont list any of these special codes. I was also looking for the code to turn off the boost. If I get this set up right i dont need the boost feature. I monitor all the temps with a prolipix thermostat. I can tell right away if there is no heat gain in the unit. http://www.weil-mclain.com/downloads/literature/ultragas/ultracontrolsupp.pdf I am going to try that tomorrow.. this is at a rental house that I own.

While holding the STEP button press and hold the MODE button. Hold both buttons together for several seconds until CODE is displayed. Release buttons. CODE stays on the display. 3)NOTE: If CODE is not displayed after several seconds release the buttons and press MODE button several times to return to STBY. Repeat step 2 again. Once CODE is displayed: 4) Press STEP button once. 5) Use the + or - buttons to make the display show C-05. 6) Press the STORE button. 7) Press the mode button several times until PARA is displayed. 8) Press the STEP button until P-5 (or P-05) is displayed. This is the outlet water temperature the boiler tries to maintain whenever the outside temperature is higher than 32 degrees ( the fixed setting on the curve). 9) Use the + or - buttons to make your desired adjustment to this temperature. 10) Press the STORE button to save this change. 11) Press the MODE button until STBY is displayed to exit. This should make the change you are looking for. You can experiment with this setting to accomplish your desired heating preference. Good Luck Kirk Rich

I guess I could make it 190F but what I really am looking to do is shift the left side of the curve up so that at 55F or so I hit 120F. If I could do that I would then want to turn the boost off. Is that possible? I already have that set at 185F. I guess I could make it 190F but what I really am looking to do is shift the left side of the curve up so that at 55F or so I hit 120F.

This is the setting that the water temp will operate when the outside temp is 32 or lower. It also changes the curve (Fig.5 page 10) to a steeper response in relation to lowering outdoor temperatures.

I checked through the control suppliment and see where you set the design temp and the target temp at the design temp but I dont see anywhere to set miniumn water temp. I am running Slantfin, thinfin baseboards and they really like 120 degrees or more. I find on warmer days it starts off with the target temp too low and it take about 30 minutes before target temp kicks up via the boost feature before the the room temp starts to rise. I use proliphix termostats monitored by intherma.com(highly recommend) and it is really easy for me to see the temp not go anywhere for a while and then ramps up hard as the target temp starts to rise. Is there a way to set a miniumn target temp on the series 2? If I can get that to work properly I would love to turn the boost feature off but I dont see a way to do that either.

This has happened a few times to me there is a parrameter for this but if you donot have the controll supliment you will not be able to change it yourself. Lisa, is there any way you would be willing to e-mail some pictures of your boiler so I could have a look at them. In no way should a seal have been removed from anything on your boiler. I realy think your boiler is piped incorectly. I hope you can get your boiler fixed before it gets to cold. FIND SOMEONE THAT KNOWS HOW TO SERVICE THE ULTRA John, No you should not take out the storage tank and put in a instant heater. Your system should work fine if piped correctly. What size pump is on the hot water tank? What size tank and pipe is piped into your tank from the boiler? What type of water tank do you have? What size piping is going in and out of your boiler? You also said renovated house, what do you have for heaters fintube baseboard, radiators,radiant. And I am going to assume you have a serries 3. Take a look at the boiler piping manual and see if it looks like your piping. A little more info will help figure out what is happening. Dave, Do you have city water or well water. Are you using circulators or zone valves (If zone valves there should be 1 system circulator (system circ may not be running) ? Do you have castiron radiators (they have lots of build up in them that may plug the passages in the boiler if not purged and flushed)? Is there a flow controll on the supply side of the boiler (that could be stuck). What size pipe do you have in and out of your boiler? I will check back later to see if I can help. IT IS VERY IMPORTANT TO HAVE A SERVICE THECH THAT KNOWS WHAT THEY ARE DOING WITH THE ULTRA BOILERS. Some companies install these and have no clue how to fix them. If you cant find a good tech go to a plumbing/heating wholesaler around you and ask them if they know of any one that knows how to work on them. Kevin,

Just started having problems. Other day had E-29 code. Pressed reset button and yesterday boiler kicked on and ran for 6 hours. Then getting 0-76 code (I believe this is standby with current water temp in system). Today restarted boiler and it ran for approx 4 hours. The code is again 0-70+/_ . I believe it gets stuck in standby mode. When I press reset boiler appears to attempt to start as blower fan is spinning but will not accellorate and no ignition visible. It is always returning to the O mode. Any ideas? Also I was away when system was installed and didn't realize 30 day warranty requirement and just registered my system the other day (19 months after installation) Will my warranty coverage start anytime soon? Tks, Paul Hi Kirk:

The first few weeks it worked fine. Then it began to lock out and the error code was water flow. So my plumber contacted Weill Mclein and they told him to replace the pump. He installed a TACO. They also replaced the board for us free of charge. It worked for awhile and then it began locking out daily for high temp. So my plumber followed their techs directions and he changed some of the parameters. It worked fine for about two weeks and now it is locking out all the time. Our plumber suggested taking the water heater offline and putting in a instantaneous water heater so it will not rely on boiler. What do you think or know about this?? We are afraid to leave the house when it gets cold fearing the boiler will lock out and our pipes will freeze??? John Hello- we installed the Ultra 155 boiler in our newly renovated house.
