Intellicenter low voltage connections

[Cesar P.]

Hi all, I searched for answers here but found more confusion than answers.

I am wiring all the low voltage connections to my intellicenter using the RS-485 ports. I have an IC60, intelliflo, and an ultra temp heat pump. I connected the IC60 and the intelliflo to the J4 and J5 com ports respectively but now I don’t know where to connect the ultra temp. Instructions say to use J2 for gas heaters, will it also work for my heat pump? The other section of the heat pump manual says to use the RS-458 but I only have two com ports, do I need an expansion pack then?

I also read something about if you use the RS-485 for the ultra temp, then I need a solar sensor?? Or to trick it with a resistor?? The kit only came with air and water sensors and I don’t plan on having solar.

Thanks in advanced!

There are two RS-485 Comm connectors on the main PCB. You can insert two wires under each screw without problems. That lets you connect four devices.

If you have the IntelliChlor Power Center card it has three RS-485 COMM connectors on the bottom, left, and right sides. That lets you connect another five devices.

J2 is for 2-wire fireman's switch control of heaters, not RS-485.

When you connect the UltraTemp to Pentair automation using the RS-485 data connection, you need to add a solar temperature sensor in addition to the air and water temperature sensors. The solar temperature sensor can be left loose in the load center. The automation system does not use temperature readings. It just looks for resistance.

A 10K resistor will work and is less expensive. Or you can install a temperature sensor.

You can steal the air temperature sensor and connect it to the solar sensor screws to test it immediately until you get a resistor.

Thank you so much! I will double up on one of the comm ports. As far as the solar sensor goes, I have some 10K resistors laying around from my EE college days LOL. I’ve been waiting for this moment my entire life. I’ve been telling my wife that they will come in handy one day and today is that day. Hahahahaha. Thanks and Happy New Year!
