Electronics / Re: thermostat for infloor heat

I saw this thread and was wondering, since it cycles the pumps once every 24 hrs to prevent pump seizure, does it do this even in the summertime when there is no demand. This would be great for me so I don't have to remember to cycle the pumps year round. Tim

If you can find someone that rents tools and carries the Husqvarna cut n break saw, it will do from 8" square on up, to a depth of 16". It doesn't require very much water either. Tim

Electronics / Re: New Guy with A Zone Controller question

I wonder if I can just use the zone controller I have and just add a relay then, it operates all three zones fine, but the circulator pump was operated by the now removed boiler.
Otherwise, what about;http://www.supplyhouse.com/Azel-Technologies-SP-82-2-Zone-Pump-Controller-Switching-Relay-with-Priority-Protection, this says will operate a system pump besides the zone pumps.
It appears that even though I have 3 zones, only 2 pumps because the basement zones share a circulator and are operated by Caleffi zone valves ahead of the current pump relay box.

Electronics / New Guy with A Zone Controller question

I'm new to the OWB world, currently installing a Portage and Main BL 2840 to replace a Propane fired condensing modulated boiler that was replace once under warranty for leaking, and then the replacement lasted 4 yrs more.
Boiler was for radiant floor heat in the entire house ( 3 Zones) and domestic hot water. I have separated the DHW from the radiant boiler as I don't wish to burn during the summer months. I installed a Geo springs heat pump for that.
The OWB will run to a heat exchanger, replacing the boiler entirely. My 3 zones are operated by 2 pumps on the supply side, (two basement zones share the same pump, and both zones share the same return pump.
My problem is finding a zone controller that will operate 3 zones that will operate the return pump no matter which zone calls for heat.
When I look for zone controllers, a lot of the technical info is not listed. Anybody with any ideas? Thanks, Tim
