I am going to upgrade to a new Intellicenter controller for my pool/spa. Had an old Compool LX3800 system. Can anyone give me insight on how to wire a heat exchanger, supplied by a domestic boiler, into the Intellicenter? Here is my set up.
I have a pool/spa (one body of water.) 32000 gal inground.
The pool plumbing has a heat exchanger plumbed into the system. It was used with an on old doemestic boiler and Compool LX3800. I replaced the boiler with a NTI 340K BTU unit.
The domestic boiler controller has the thermostat wires run to the pool control room. The heat exchanger is two 130K BTU plumbed in parallel ( so total of 260K BTU).
Can I just run the boiler thermostat wires in series to the Intellliceter heater dry contacts and then through the pressure (flow) switch which is installed near the heat exchanger? The old system had a temp setpoint monitor which I don't think I need any more because of the new stlye boiler and Intellicenter.
 
DR,

The IntelliCenter closes or opens the "heater dry contacts" based on the water temp probe, normally between the pump and the filter..

When the IntelliCenter senses the water temp is below your set point, then in closes the heater contacts, which will turn on whatever heater is attached. When the water temp is above the set point, then the IntelliCenter opens the heater contacts and the heater shuts off..

If your heater worked with the LX3800, it should work with the IntelliCenter.

Thanks,
