Operation of the PRIORITIZER Models

Priority Channels

• 4200 units have 4 lines on Priority 1 and 4 lines on Priority 2. These lines may each be connected to one 120 volt load, or two of them (must be on the same priority level) can be used to switch both legs of a 240 volt circuit. You could switch only one leg of a 240 volt circuit -- check the electrical code in your area.

Operation

• When ANY of the loads on the Priority 1 circuits is operating, ALL of the Priority 2 loads will be disabled (AC power will be removed from them). When NONE of the Priority 1 loads are running, the Priority 2 loads will be re-enabled.
  

Typical Application

• The 4200 unit is best suited to a home using a generator for standby power. If you have an electric water heater, by wiring the water heater to Priority 2 and your Refrigerator, Freezer, Well Pump and Furnace (as an example) to Priority 1, you will allow the water heater to run only during the times when all of the other four appliances are off. This will happen periodically throughout the day and night, keeping the water temperature right where you want it. But by lowering the total load which can be active at any given time, you can now install an 8KW generator (or Fuel Cell) instead of a 12KW unit which would have been necessary without the PRIORITIZER unit.

Priority Channels

• 2220 units have 2 lines on Priority 1, 2 lines on Priority 2, and 2 lines on Priority 3. These lines may each be connected to one 120 volt load, or two of them (must be on the same priority level) can be used to switch both legs of a 240 volt circuit. You could switch only one leg of a 240 volt circuit -- check the electrical code in your area.

Operation

• When EITHER of the loads on the Priority 2 circuit is operating, BOTH of the Priority 3 loads will be disabled (AC power will be removed from them). When EITHER of the loads on the Priority 1 circuit is operating, BOTH of the Priority 2 loads and BOTH of the Priority 3 loads will be disabled. When NONE of the Priority 1 or Priority 2 loads are running, the Priority 3 loads will be re-enabled.

Typical Application

• The 2220 unit is preferred for more strict load control than with a 4200 unit. If you need to divide your big loads into three sections instead of two in order to keep from overloading the power source, then the 2220 unit is called for. A possible application would be to run the home listed in the 4200 example above with 4 to 5 KW instead of 8KW.

Priority Channels

• 1111 units have 1 line on Priority 1, 1 line on Priority 2, 1 line of Priority 3, and 1 line on Priority 4. These lines may each be connected to one 120 volt load. You could switch only one leg of a 240 volt circuit -- check the electrical code in your area.

Operation

• When the load on the Priority 3 circuit is operating, the Priority 4 load will be disabled (AC power will be removed from it). When the load on the Priority 2 circuit is operating, the Priority 3 and Priority 4 loads will be disabled. When the Priority 1 circuit is operating, the Priority 2, Priority 3, and Priority 4 loads will be disabled. When NONE of the Priority 1, Priority 2, or Priority 3 loads are running, the Priority 4 load will be re-enabled.

Typical Application

• The 1111 unit is useful for Alternative Energy power sources, where there is a relatively small power source available, and one load at a time would be within its capabilities. The 1111 unit is also useful for sequencing four higher-power loads in a situation where you only want to enable one of them at a time.

Single-Line Model Notes

• There are also available models of the 1110 and the 1100 style. These models have three and two 120 volt lines, respectively. They operate in the same manner as the 1111 unit described above, except for the total number of channels in each unit.
