Selecting a Honeywell Aqustat

Mike K_3

I am looking for a Honeywell Aquastat that will have a high limit temperature for the oil burner circuit and a low limit temperature for the circulator circut. I do not want a low limit on the burner circuit. Can a triple Honeywell Aquastat be wired this way. I am asking this question because I have an indirect hot water tank,one circulator, 4 zone valves( 3 heat - 1 domestic hot water) and a Taco priority controller and if the burner fails, then the circulator runs and trys to heat the house from the hot water tank and kills the domestic hot water quickly. I want to lock out the circulator if the buner fails by using a low limit cutoff. Present Aquastat only has high limit for burner and thermostats control the circulator. Also, I only want one Aquastat, not two separate units. Thanks
