Looking for a Normally Closed (not NO which I understand is the std OMRON relay) for an Intellitouch Control Center

Due to a fault in an existing Intellitouch i10 +3, I am looking for a relay that is the same as the supplied Intellitouch OMRON G7L-2A-BUBJ-CB-IN but with a normally closed rather than open output circuit. All else should be the same - e.g. footprint and voltages etc. as it will fit in the same Intellitouch control box.

Any suggestions please?
 
What is the fault?

If it is that the relay is energized when you power up the intellitouch, it's likely a bad relay driver. Replace that for $1 instead.
 
It is that the valve actuator will not active

E,

Why not fix the IntelliTouch??

You could use the Pentair 2-speed relay, which has both NC and NO contacts.

Thanks,

To answer, why not fix the Intellitouch - I spent almost two hours with a Pentair tech and the only thing they recommend is replacing the board which is expensive. Thanks on the recommendation on the 2 speed relay I will look at that.

The fault is that the valve pin (VLV A and VLV B) for the valve actuator will not activate for the pool heater (or SPA heater) function. It activates for manual AUX circuits but not automatically when the heater is activated. I do not know where the relay driver for that is?

I'll explain my simple solution as you may have an easier solution (I am not an engineer just a simple DIYer). Given the actuator has 3 wires; black is common and a red and white. When power is applied to the red it turns one way and when applied to the white then it rotates in the opposite direction.

  1. I have connected the red wire to a relay that is activated (i.e. closed) when the heater turns on. Using the Electric heater special purpose relay output.
  2. I now want to connect the white wire to another relay (that is normally closed and thus opens when the same signal is received from the special purpose relay output.
Then when the Electric Heater Special Purpose Relay is activated, the actuator receives power on the red wire thus turning clockwise and when the Electric Heater Special Purpose Relay turns off, power is to the white wire turning the actuator anti-clockwise. The actuator will thus always have power but never have power on both the red and white.

If I could find a SPDT relay that can fit in the box that would work. (I believe that is all the VLV A actually is) but I don't know of one. Unless the two speed relay is that and I will investigate that. Thanks for all the input.

You should change the relay driver chips first...

They are plug in chips.

Thanks,

I apologize but I cannot see them on any diagram. Could you direct me to them? Pentair also believe it maybe an issue between the Screenlogic software and the Intellitouch board (it not communication properly) as the actuator works perfectly and is also able to activated correctly using a manually pushed AUX circuit. Problem is you cannot (per them) create an AUX circuit that will automatically activate when heat is called for.
 
if the valves A and B are working when you assign them to an Aux circuit, say assign Aux 1 to Valve A and Aux 2 to Valve B... then the relay drivers are working fine. The drivers are the socketed UNL2803 chips on the main board. This also tells me that the microswitches inside each actuator are working fine... so the problem is likely with the configuration - I don't have a heater so I'm not familiar with setting one up, but the other folks here know what's what.
 
if you have an indoor panel, you can verify that communication works by pressing the "Heat" button on the bottom... if you get to the Heat screen then your comms are good, but if you get a timeout error something is broken.
 
Firmware can be managed pretty easily... what version do you have?

if you're a DIY type there's a thread on TFP detailing how. Or you can ask a local pool store if they have the tools to do it, or there's a lot of folks on the board (including myself) that can do it for a nominal fee - but you'd have to ship the main board. Oh, and make sure that you put the latest on the indoor panel if you have one (you can't set the year past 2020 unless you have 1.190 on the indoor)

How to perform firmware upgrade on Pentair* controllers

Pentair* Controllers; EasyTouch versions 1.0XX and 2.1XX, iLink version 1.0XX, Intellitouch version 1.1XX, Mobi version 2.1XX, and Suntouch version 2.0XX Please verify that your programming port matches the picture in this thread. Note - Pentair sells a kit P/N 520957 for $559.95 to perform...

FYI - I went with the Functional Devices

RIBU1C Enclosed Pilot Relay. 1736175741836.png​


It has worked well and is a versatile relay and inexpensive at under $30. Their help desk is also very helpful which is unusual for help desks.
