Wiring for Circulators,Zone valves and Thermostats

You power the operator(s) and thermostat(s) from a transformer as shown.The end switches are powered from a separate 120 vac supply,and can be used to control a 120 vac circuit to the circulator or burner or whatever-- circulator,most likely,in your case -- and can be wired in parallel.Wiring Your Radiant System DIY - DIY Radiant HeatThis is the schematic to use with a Heat Exchanger or Primary Loop system.The pump running the heat exchanger/primary loop is called the system pump.Obviously,it needs to run when any zone calls for heat..For (either) Primary loop pump or Heat exchanger pump connections,both neutral (white wire) and load (black wire) to the System pump connections at the bottom of the relay box Transformer Cooling System and Methods Electrical4U singapore transformer tank heat pump circulation system size#0183;The heat dissipation rate can be still increased further if this oil circulation is accelerated by applying some force.In OFAF cooling system the oil is forced to circulate within the closed loop of transformer tank by means of oil pumps.
