taco zvc-406 to tekmar 260

Im having trouble hooking my new zvc-406 to my existing tekmar 260. This is on a toyotomi OM-180 so i don't have a aqua stat but I thought that if I hooked up the isolated end switch off of the zvc406 to the boiler demand on the tekmar. Im ignorant of controls so any help anybody can give would be of appreciation.

thank you

    I thought if the zvc was powered that so would the end switch I jumped power through it and it now controls the tekmar.
