Value position to heat pool

Bought a house with Hayward pool system. I think it is aquadyne and an air spa but not sure. The controls to turn spa on are valves and the heater is a Hayward that has standby spa and pool. I know how to heat spa and turn spa on but not sure how to heat pool. Do I just change settings on Hayward heater to pool or do I have to turn the valves as well?

SOURCE: I have a Hayward H series spa/pool heater. It will not light.

IF stands for ignition failure, one possible cause is that the two sparker prongs are not spaced properly, i have seen this before several times. The correct distance for them to be spaced apart is the width of two quarters side by side... not like this....OO, the other way so the are flat. To access that you have to take out the heat exchanger, which requires unhooking high limit switches in the back, unhooking the pressure switch, thermostat wire, and plumbing...just remember where everything goes. Before you do that though check this simple thing...there are a number of brass orifices that shout gas to the burners, use a 7/16 wrench to take off the one that is to the extreme left, which is on the igniter side of the heater, inspect the orifice to see if there is blockage, like a spider web or something. If it is blocked, clean it out and also look down the burner itself to see if it is free of blockage. And because we all make simple mistakes.......make sure the gas is on.

SOURCE: MIni-Max 400 heater cycling

sounds like you may have a water chemistry problem more than a heater problem. High pH coupled with the heat of the exchanger in the heater will allow the calcium in the water to precipitate and scale the tubes of the exchanger. Make sure your water is balanced, pH 7.4-7.6. Water balance factors include pH, total alkalinity, calcium, TDS, and temperature. Use the langlier saturation index to determine your water balance. If your water is balanced, you may have a bad thermal governor. If you hear the heater water hammer and bang around and then shut off, you definitely have a scale buildup in the heat exchanger tubes. Hope this helps...

SOURCE: I have Jandy RS4 system with 4-button poolside

Pull the cover off the control panel. You will probably find a button which would be accessible from outside the panel with a paper clip or pencil but is unlabeled. On the board itself by the button, in small letters it should say "reset". Push the button and see what happens.

SOURCE: my hayward heater gives a LO error when trying to

One of your limits is not working or not wired up. An easy way to check the limits - Water pressure switch, Hi limits, air pressure switch all of which have 2 wires going to them. Unplug one item and connect the 2 wires together ( paper clip works fine ) Then retest, if problem does not go away remove paper clip and reconnect wires and move to the next limit. The limits are located in the black plastic header. Always make sure water is flowing through the heater at all times while checking the limits.

How do I turn on the heat and the spa in the pool?

You must first make sure the filter pump is on and running (primed). If you have a pool spa combo, you will need to turn on the heater by making the desired temperature higher than the current temperature. This is a call for heat. You must then move the suction and return valves to **** and return to the spa. This is accomplished either by moving the valves manually or by putting it into spa mode if you have a control system. You didn't say whether or not you have a manual or automatic system.

My filter and pump will not retain the prime after turning off. Its a pantera sand filter. I can hear an air hissing sound coming from the multi valve port

Either you have a bad spider gasket inside the multiport valve or a bad threaded fitting going into it. Check for leaks around the multiport and backwash line. You'll have to take apart the multiport valve to make sure the spider gasket is not damaged or out of place. Make sure to install the multiport valve in the same position. You can get a replacement gasket at most pool supply stores or online.

Turned the temp for the spa up to 100 but it heated the pool too!?!

If you have automatic valves that switch over to run the spa, make sure that the valves turn completely to where they are supposed to be. Normally it will be about 180 degrees from where they are when in pool mode. If you have to change the valves over manually, make sure they're in the proper position. The only time this can happen is if the valves are not in the right position allowing the heated water to return to the pool. The thermostat on the heater will heat the water to the prescribed temperature no matter how you have the valves set. So if you place it on spa mode, it will heat whichever body of water that is flowing through it to that temp. If you have an automation system, double check the valves. That is probably where your problem lies.
