$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).
If you turned on the thermostat and the heater (or A/C) didn't come on, it may be a problem with the thermostat and not the furnace. First things first, make sure that all the settings on the thermostat are as they should be.he thermostat control is low-voltage and poses little risk, but best practice is to turn off the power to avoid injury or damage to equipment. The sub-base is screwed to the wall. You will probably see two or four wires coming from a hole in the wall and connected to screw terminals on the sub-base.
