i have a new danfoss pipe thermostat wich i want to wire to my water new water pump, the thermostat has 3 terminals and an earth the terminals from left to right are 3NO 1CO 2NC , i'm assuming that the 3NO is normally open , 1CO is the live common , and the 2NC is normally closed , however the water pump only has 3 terminals ,live neutral and earth,i have 0.75mm squared twin and earth, i'm also assuming that one of the neutrals will become live when the stat reaches it's required temperature and this in turn will trigger the water pump to start pumping,any help with the wiring would be much appreciated thanks.
