When I change the temp. setting it keeps heating at original temp

Hi,

please check that the control panel can control other things outside of the temperature. If this is the case, then maybe the pool components (ie thermostat) were not added properly or are incompatible with your control panel. If the control panel does control anything, then the full re-installation needs to be done. Thank you.

Not much info here but SL could be the mode setting. Typically modes are SLEEP, ECONOMY and STANDARD. Standard maintains your set temp at all times even if it has to turn on outside of normal filtration cycle. Economy only heats during a filtration cycle, and sleep will only heat within 10 degrees of set temp and only in filtration cycle. This cycle is really only useful while going on vacation or other extended periods of non-use. Not sure how to help change modes without knowing what spa pack you have but you should be able to find the owners manual on line with a little research.

when the temp drops 1 degree, it will begin to heat up again. you may need a better cover, especially if it's cold outside. i would set it lower (like 100) and then when you know you are going to use it, turn it up and give it an hour or 2 to heat up...i used to have a timer on my old one and i loved that bc i had it set to heat up each night "just in case i wanted to use it"

The system has one temp but the heater temp should be turned all the way up outside on the unit as well

I had the same problem last year, I talked to a spa guy and he stated that the temp sensor was probably covered in bio crud. He also stated that the tub should be cleaned with a hot tub flush. After doing that I have not had a problem with the temp settings.

The heater may be wired just fine. The aqualink uses its water temp sensor to call for heat based on what you've set the thermostat to on the aqualink. However, most heaters have built in thermostats that over-ride the aqualink. Those thermostats come factory defaulted not to go over 94. Check your heaters manual on how to adjust the thermostat on the heater. Your heater should have its thermostats set to 104 and the aqualink will control the actual temp of the water by calling for heat based on what you've set the thermostat on the aqualink for. Hope this helps.

IF when the spa control calls for heat and it trips the breaker when the heater comes on then you have a bad heating element and it will need to be changed.
Disconnect the power to the spa. Disconnect the two wires going to the heater and then turn the spa back on.
If the spa stays running without the heater attached then that will be your source of trouble. New heater and you will be all fixed up.

There are many variables to this......

How big is your pool how big is your solar system.

Solar temps don't rise quickly ever, and definitely not when the temp is only 75 outside.

You need 80-90 degrees or more on the roof to see quicker results, if the water temp is currently at 70 and it's 75 degrees outside and 80 on the roof you will barely get any change.

You will also lose the heat at night due to lower temperatures.

Once it's hotter outside and warmer at night you get the gains and keep them.

Hope this helps

I believe the unit you are describing is a heat pump. Heat pump are great when the temperature isn't below 30 With low ambient temps. outside it is much more efficient and comfortable to run aux. electric heat from the heat pump.

There are four sensors for ambient tempurature and they work in unison to provide information to the temp reading on the dash, the heater control head ( where to direct air, blending of warm/cold/outside/inside air flapper controls) depending on the ambient temp and the inside air temp sensor located just above the radio as well as the sun sensor on the top of the dash as well as the a/c compressor head.

When you start your car, the body control module takes the readings from all sensors, outside air temp located in front of the radiator, air temp sensor located in the airbox ( senses temp of air being drawn in from the outside into the air box), coolant temp, inside air temp sensor and the sun sensor on top of the dash (this is why it takes a few seconds for the climate control system to begine when you start the car). The intake air sensor is 1st priority, inside air second, coolant third, ambient 4th and sun 5th. For instance, if the sun sensor reads the sun is hot but the interior sensor reads cold, the inside akes priority. The goal is for the system to achieve a tempurature inside the car that matches the selected temp. It uses all of the sensors to set the system up to achieve that goal as quickly as possible.

Example; Its mid afternoon, sunny and 40 degrees outside adn your in stop and go traffic. The intake sensor reads 40 degrees, the outside sensor reads 60 degrees (heat from radiator...engine heat protrudes into cabin) and the sun sensor reads high (sun is strong). The system is set for 72. priority one sensor reads 40, inside sensor reads 65, ambient reads 60= system will blow hot air to the floor out put, dash outlets will lightly flow 65 degree air so the sun doesnt roast you yet your feet are cold(if it blew hot air from all outlets, your upper body would be hot but your legs/feet would be cold). as the interior sensor reaches desired temp, air will be distrubuted through thee dash, defrost and floor with the warmest air coming out the floor and defrost, coolest air out the dash vents. Its a complex system!

The two sensors that will screw the system up the most are the intake and interior sensors. the system will function reasonably well with just those two sensors though it wont blend air temps between outlets if the sun sensor isnt working. If the outside sensor fails, it simply uses the intake sensor, if the intake sensor fails it will rely on the front sensor. However, since the intake takes priority over the outside sensor, if the intake sensor sends incorrect resistance info rather than failing, it will take priority and cause the unit to malfunction such as in your case.

The intake air sensor can be changed from the outside with patience. If it where me, I would pay the two hrs labor and let the dealer do it right.
