wwsd two temp sensors

hydronicsmike

...I am having slight difficulties understanding what exactly you are after. But by the sounds of it, I would guess you may want somethng like a 256 tekmar Boiler Control with apermanent demand and a system pump that is hot wired to run continuous?

If the pump should also not run continuous, it would be a 260 Boiler Control.

Hope this helps. If not, call 250-545-7749. I am sure we got something for you.

Anyone have two outdoor sensors such that when the wwsd

cuts off the boiler temps it circulates water constantly thru all the zones at a cooler temp in the Field?

Do you mean using two sensors to allow switching between two supply curves for heating periods with and without significant solar heating (such as day, night, overcast) to better match supply temps with heat loss?
