$18,000 - $20,000. More than $20,000. The total amount spent per pupil by district in the 2011-12 school year by elementary and K-12 districts. The darker the color, the higher the spending.
b) Set a voltmeter to the 300 volts scale. Place test probes on terminals 1L and 3L (see diagram) of the high limit portion of the thermostat. The meter reading should be the input voltage of the heater (see rating plate of the water heater). If not correct voltage, check for loose connections and blown fuse or tripped circuit breaker. c) To verify that the high limit switch is closed, place test probes onto terminals 2L and 4L (see diagram).
High voltage systems. High voltage systems are usually electric baseboard heating systems or other radiant systems powered by electricity. High voltage thermostats are built into the wall and have 2-4 thick wires that come out of the back of the thermostat. These wires connect with wire nuts to corresponding wires coming out of the wall. Only high voltage thermostats have thick, stranded wires coming out of the thermostat itself.
