set up the 925 control that comes with the boiler?

I have 1 zone radiant, 1 zone DHW, 1 zone for pool and 1 zone for hot tub.

Thanx all

If most of the house is radiant just set the aquastat on the 925 controller to your max design temp for your radiant and as for the domestic hot water and the pool heater htp has some piping and alternative control set ups for both the pool heater and dhw proiduction .Are you using the vision 1 or 2 if it ,s a vision 2 then you have some belimo 3 way valves and a vision 2 controller if so i believe you must give a address to each valve then program the perimeters for each valve .I do belive you can still use the vision one DHW prority and piping that protion as HTP shows in there diagrams as so to shut main boiler pump off and go to full output and start the domestics pump ,of course unless you use a external multi circ relay your systems pump will continue to run i have used taco sr505 with domestic priority and used a isolation relay off the munchkin to make the taco relay and then all my suystem pumps shut off as does the boiler pump ,it's a little extra but what the hell .good luck and peace clammy
