How many volts is a circulator?
By default, all Taco circulators and Grundfos circulators are 115 Volts, 60Hz.
What is head range on a circulator pump?
The head range is the number of feet a pump can raise or lower a column of water at atmospheric pressure. • In a closed-loop hydronic system, the circulator pump can be cast iron, because the water used is de-oxygenated to prevent rusting.
What happens if there is only one circulator pump?
If there is only one thermostat, one heating zone, and one circulator pump it’s simple, there is nothing to sort out, continue with INDIVIDUAL HEAT ZONE CHECK. There will be no zone valves, just a single pump and its controls to turn the circulator pump on and off.
What should the volts be on a circulator pump?
Expect the reading to be about 120 volts. Place the sensor on the end of the black wire from the meter onto the terminal from the transformer that goes to the pump motor marked “Neg,” or “-” to test the transformer. Place the sensor on the end of the red wire from the meter onto the terminal labeled “Pos” or “+.” Read the voltmeter display.
How many relays are needed for a circulator?
Two or more circulator relay switches, one relay for each circulator pump, will be installed to turn on and off each heating water circulator if more than one heating circulator is installed.
What to do if your circ pump is not working?
Check that your power is on, the breaker or GFCI test button are not tripped, all valves are in the open position. Follow the circ pump plumbing, and look for any kinks in the hose.
Why does my circulator pump not have power?
If the circulator pump has power but the pump is not spinning then there is an internal problem in the circulator pump or pump motor or its impelller. Some circulator pumps make enough noise and vibration that it’s obvious if the pump is running.

What to do if your circulator won’t turn on?
1. Check that the thermostat is calling for heat and the room temperature is below the thermostat set temperature. First set the room thermostat all the way “up” so we know it’s set above the room temperature. 2. Check that the boiler temperature is above the circulator cut-in temperature controlled by the aquastat.
How can I tell if my circulator pump is running?
Check the circulator relay has power and is switched “in” or callling for the circulator to run. There will be a relay switch either in the aquastat on your boiler or one or more additional circulator relays controlling additional circulator pumps if there is more than one circulator pump.
