New to this forum and desperate !
Just cannot understand the instructions for setting up that came with my new Hayward heat pump.
The heat pump is a new Hayward HP50TA HeatPro.
The controller is an old AquaLink RS4 (worked fine with my old heat pump).
I connected up 240 volt wires to the two terminals inside the heat pump as per instructions.
I connected up the two low voltage wires from the Aqualink to the two terminals inside the heat pump after removing the jumper bar as per instructions.
On the outside there are three touch pads for SET and UP and DOWN arrows and a gobbledygook display. At this point I am stuck. Intuitively I cannot understand how the pool and spa temperatures can both be set by the pump and controller at the same time. Is there a setting to give the Aqualink priority ?
Many thanks in advance for any help please. Preferably a procedure for a knucklehead like myself to follow!

Steve,

Welcome to TFP... A great place to find the answers to all of your "heated" questions... :shark:

I am not a Jandy guy, but logic says that for the heater to understand the difference the Pool mode and the Spa mode, you have to have more than a two wire connection, which only gives you on/off control. I suspect that you need to use a three wire control cable. (See update below)

I'll see if I can round up one of our Jandy experts to chime in, but in the mean time, you might want to see if your heat pump manual shows a three wire connection..

Thanks,

Jim R.

UPDATE.. Well once again I am full of it.. :D Check out page 10 of the Heat pump manual... https://www.thepoolfactory.com/media/wysiwyg/pdfs/hayward_heatpro_hp50ta.pdf Which shows the external connection using just the two wire on/off connection. It also explains the set up process.

Thanks Jim for your response and your welcome. I can confirm that my old system with the existing Aqualink worked fine with just two wires from the Aqualink to the pump. Thanks also for the link which actually is the manual that I have supplied in paper form with the pump. I have read the paragraph on page 10 about an external controller many times and am still baffled. I don't want to set the pool heater to off as implied in the instruction. I just want pool at 82 and spa at 102 as before. How is the "menu" accessed ? What is the board they refer to ? Surely I don't have play around with a circuit board ? I am very irritated with Hayward for supplying quite inadequate instructons and information.
 
Steve,

I am used to heaters where the automation system has a thermostat and the automation just tells the heater to come on or turn off at the desired temperature..

I looked at your heater's wiring diagram and it appears the only thing the automation system can do is tell the heater that the pool is in the Pool Mode or Spa mode. It does not appear to me that there is anyway for the automation to shut the heater off, as long as the heater is in "External" control it will heat to either the pool temp or the spa temp.

I've sent out a bat signal for one of our heater experts to chime in..

Tell me how your old heat pump worked...

Thanks,

Jim R.
 
Are you connecting the two low voltage wires to the P and S terminals? J7.

Once connected:
Turn on the heat pump.
Set Pool Mode to Off.
Set Spa Mode to maximum temperature.
Access the setup menu.
Select mode E (external) on the P_S menu.

When the external switch closes, the heater will run.

The temperature is set in aqualink. The aqualink tells the heater to turn on by closing the switch.

To select the pool or spa mode
The unit can keep two temperature settings in memory: one for pool mode (max: 95°F/35°C), and the other for spa mode (max: 104°F/40°C). To have access to either program, press the SET key until you see P_S and by pressing one of the arrow keys, you can switch to POL or SPA. Once the heating mode has been programmed, it will be displayed for five seconds, and will then return to the actual pool water temperature. The lights on the right side of the display indicate the chosen heating mode.

Select Pool Mode and turn the temperature down until the display says Off. Then, select Spa Mode and turn the temperature to a few degrees above the desired Spa temperature.

The control board should be behind the display. The display is on one side of the control board and the P and S connections are on the other side. Lower right green terminals.
 
JamesW,

So, if the OP set his heater to 82 in the Pool mode, instead of shutting it off, and set his automation to 102 in the Spa mode, it would heat the Spa to 102 when in the Spa mode, and when not in the Spa mode would heat his pool to 82?????

This what the OP wants to do but I'm not sure how that works...

Thanks for your help on this one...

Pool mode or spa mode is set and controlled by the Jandy aqualink.

If the aqualink closes the switch, the heat pump is switched to spa mode and the heat pump will run until the aqualink reopens the switch.

If the aqualink opens the switch, it switches the heat pump to Pool mode, which is off.

So, the heat pump is just remotely switched on or off by the aqualink based on the settings in aqualink.

It's basically the same thing as a gas heater using a fireman's switch where you set the heater to spa mode and turn the temperature up.

When the Aqualink is in Pool mode and wants to turn on the heat pump, the switch closes and the heat pump goes into Spa mode and heats until the aqualink reopens the switch at the pool set temperature.

So, it's a little bit confusing to have the heat pump go into Spa mode when the aqualink is in Pool mode. You just have to ignore Pool and Spa mode at the heat pump. It's just how they make it turn on and off remotely.
 
Thanks guys for all your responses. I assumed the heat pump was faulty and the supplier has collected it and is shipping another one to arrive this coming mid-week so I will try your suggestions as soon as I have got it installed.
The AquaLink worked ok before (setting the required pool and spa temperatures via the AquaLink progamming buttons or just turning on manually by pressing the AquaLink spa or pool heater buttons). The pool and the spa could never be pumped or heated simultaneously, I think this might be because it's a two wire and not a four wire set up.The old heat pump was not a Hayward and was inherited when we bought the house so I dont know how it was set up initially.
I have viewed rather an unclear utube video and I get the impression I should select E on the menu (for external ?) but maybe I am getting confused.

If there's a jumper on the J7 terminal block connecting the P and S terrminals, remove the jumper.

To set to external mode, I think that you press the Set button until you see Internal or External mode and select by pressing the Up or Down arrow.
 
The heater has terminals inside the electronics box for the two 240 volt wires and the ground wire. Outside the electronics box to the right are two terminals for the 24 volt wires. The heat pump comes with a metal jumper connecting these two terminals. Reading the Hayward manual it talks about removing this jumper and routing two wires to the "external switch housing" (do they mean an Aqualink I wonder ?). There is no mention of the P and S terminals on the circuit board inside the electronics box or connecting any wires at all to them.
 
Interesting ! I think you have put your finger on why I am not understanding the responses to my original question. The online link you refer to is dated 10/2009. (See bottom of title page). The printed manual that came yesterday with the new heater is dated Rev F 0616. I guess this means revised February 2016. I see now that the drawing on page 10 of the earlier version is of the bottom right hand corner of the circuit board. On the revised version (figure 4 on page 11) the drawing is totally different. It shows a "terminal block". It looks though maybe Hayward have changed the wiring so the p and s terminals on the circuit board are no longer used and the new pair of terminals outside the electronics box only need be used after removing the jumper. Sorry but being new to the forum I am not yet able to attach photos or links. I have not looked for the latest manual.
 
Probably did not make myself clear. I want the spa heated to 102 and the pool heated to 82. I have set these temperatures on the Aqualink, no problem. I can't see how to do this on the heat pump controls. I have called Hayward three times. People there try to be helpful but I got different instructions from each and only after they had gone off to find the right piece of paper two saying that they often had inadequate information from their design side. Hayward obviously do not train their customer relations people properly. It is unbelievable that they sell an $1800 piece of equipment without full installation instructions.
 
Just remove the jumper and connect the 2 wires. Then, leave the heater set to Spa mode and set to 104 degrees.

You don't program the heat pump. You leave the heater set to Spa mode and set to 104 degrees.
 
You dont use the temperature controls on the heat pump when it is controlled by the Aqualink. Just set the heat pump to the max temp. The Aqualink should have its own temperature probe in your plumbing and will cycle the heat pump to maintain the spa or pool temperature set in it.

Steve,

Am I right in saying you want the pool and spa to heat at the same time, one to 102 and one to 82? Or do you expect the pool to heat to 82 only when in the pool mode and the spa to heat to 102 only when in the Spa mode. Do you want plan to maintain these temperatures constantly, or only when you want to use the pool or spa?

Thanks,

Jim R.
