    Mastertemp 400 service heater and HLS leds on

    After looking at wiring diagram some more realized there are 2 sensors on the other side of manifold lower one is HLS. Jumped the lower one and heater starts and runs fine now. So I am ordering new HLS sensor from Amazon. I was jumping AGS sensor earlier which is on other side... While I'm at it...

    Mastertemp 400 service heater and HLS leds on

    Heater has been working fine for past year since fixing gas flow issue (thank you to this forum for helping me troubleshoot and solve that issue). Now I am back for more advice. Heater does not fire and service heater led is on. Immediately after turning on power the PS led comes on, then a...

    Pentair IC40 and low chlorine level, nitrates?

    Yes water restrictions still in place at least for outdoor water watering I believe pools too. I should only need to remove 10% to get the salt down to 3600 and CYA to 80. Or maybe I can just add liquid Clorine for next couple months to keep at 5ppm and deal with later this summer.

    Pentair IC40 and low chlorine level, nitrates?

    And they were wrong on salt too. I checked it using K-1766 kit and I get 3800. The SWG is registering 3950. So I am done with Leslie's they were the ones that told me to add 2 bags of salt in the spring. I guess another example of them just trying to sell more chemicals - I'm sure no surprise...

    Pentair IC40 and low chlorine level, nitrates?

    You're right their test was way off. I just tested myself used up my last R0013 and I get CYA of 90. Also last night before posting I added 1 bag of their "powder plus" and the SWG has been running 100% for past 12 hrs. Just checked FC is now 5ppm and CC is 0. I'll read up on SLAM now. I am...

    Pentair IC40 and low chlorine level, nitrates?

    Yes I am getting some light green algae in the deep end of the pool that easily brushes off, which I know from experience is due to lack of chlorine. I test it and its 0 so not much surprise there! I have Taylor k2006 kit using the sbd titration test so i know my test is accurate. My CYA is...

    Pentair IC40 and low chlorine level, nitrates?

    I'm having problems this season with the system being able to keep chlorine in range. System is about 3 years old. First year worked great consistently had 2-3ppm all summer with IC40 set at 25%. Second year started out ok but then I had to increase output to 50% to keep chlorine in range then...

    Pentair mastertemp 400 cycling due to low gas flow?

    Yep it was the brick. Got a replacement today, plugged it in and now I can connect local and from mobile app again. So now just need to install the new thermostat this weekend and then will be 100% operational again, and just in time usually April is when it gets warm enough here to start...

    Pentair mastertemp 400 cycling due to low gas flow?

    I'll give it a try. But when I ran the updater last time it could not find the brick to update it. I'll check support site make sure I have latest versiond and try again. Sent from mobile using Tapatalk

    Pentair mastertemp 400 cycling due to low gas flow?

    Ok thx that's good to know for future reference. No groove on this one. The plumbers that came out to look, and the gas company when they replaced the meter did not catch it either. Sent from mobile using Tapatalk

    Pentair mastertemp 400 cycling due to low gas flow?

    I found this diagram online it actually acts as a temperature controlled mixing valve when the outlet temp reaches 120 or higher the thermostat opens and allows "cool" inlet water to bypass the heater coils thus lowering outlet temp into safe range. How a Gas Pool Heater Works Sent from...

    Pentair mastertemp 400 cycling due to low gas flow?

    Yeah that's what I immediately realized when I saw it too, looks like it's been this way since the beginning. And check out the position of the bolt compared to the open valve position it has to be at an angle I have never seen that before on a valve like this usually the bolt shroud be square...

    Pentair mastertemp 400 cycling due to low gas flow?

    Seems my brick is bricked. I called pentair today they said it has not connected to their system since the fall. I had a problem with last year too tech support did some updates while remotely connected to my PC that fixed the problem for a few months before it failed again. This time I think...

    Pentair mastertemp 400 cycling due to low gas flow?

    Important point. Yes I use Pro Dope on all gas threads. This is not a typical DIY project and should only be done by someone with proper plumbing experience. Sent from mobile using Tapatalk
