Can that pump be installed like that with the rotor shaft in a vertical plane? Most circs are installed with the rotor shaft in a horz. plane. The bearing surfaces are designed for a radial load not a constant thrust load.

What are you controlling with the JC A419? I'm formilar with this controller, it can be set in a couple of configurations for heating and cooling applications, but I'm not sure what you would be controlling? Also, what model number is the wilo pump you are using? Looks like your comming right along.

TCaldwell said:tat,can you clear this up for me, i was under the impression that the concept of outdoor reset was to use the variable speed pump to mix the supply temp based on the reset control calculations, however the gpm delivered to the hx would stay constant. and that if you wanted to vary the flow rate to the hx, that would be with a vsd pump controlled by the delta t with sensors on the supply and return, as your delta t became larger the pump speed would increase to try to close the differential. thanks tom
TCaldwell said:joe, being that the garn is a burn and store, with a widely fluctuating supply water temp as the day progresses, and not a relatively constant temp boiler that can controlled with a setpoint high limit. would the outdoor reset be beneficial. with the garn burned 12 months a year would it be better realizing the fluctuating supply temp to use a variable speed circ based on a delta t between the supply and return, basically only if there is demand will the circ be pumping supply water based on the delta t need, if no need the hot supply water will stay in storage, thanks tom
