D. APPLIANCE PUMP CONTROL TO ASSIST IN PURGING AIR FROM SYSTEM LOOPS
Before powering up the control assure the thermostat connection is disconnected on the field connection board. Apply power to the
appliance (Note: The appliance will fire the burner and heat the water inside the
storage tank to the domestic hot water temperature set point). Press . The display
can show the temperature set point of the appliance. Press the
▼ and ENTER keys
simultaneously and hold for 1 second. The display will read:
The central heating pump will come on. Run pump until all the air has been purged through each circuit. If you press the
▼▲ keys
simultaneously, the central heating pump will shut off. The display will read:
Once the system has been purged of air, the installer can now proceed to program
the control and system design parameters.
E. PROGRAMMING THE TOTAL SYSTEM CONTROL
Before programming the Total System Control to the specific needs of the system, verify that the system is ready for operation. Be
certain that:

The Domestic Hot Water system is filled with water that meets the qualifications and all air is purged.

The mixing valve supplied is properly installed.

The Hydronic Heating System is filled with water and meets all qualifications and all air is purged.

The outdoor reset sensor is installed in a proper location.

The electrical power supply is installed by a licensed professional.

Turn down thermostats, making sure that they are set so there is no call for heat while programming.
This section discusses how to program a few of the major sections of the control parameters for optimum system
performance. See the control overview section for more detailed information on the operation of the display and other
parameters.
1. Turn on the main power switch on the top right of the burner cabinet. NOTE: At first startup, the water in the tank is cold and the
burner will ignite. This is normal operation. You can continue to adjust settings while the burner is running.
2. Press and hold ENTER for 4 seconds until you see the screen to enter the log in access code shown below.
3. Use the  key to move the blinking zero to the left most zero. Next, use
▲ and ▼
to log in 600, the access code. Press ENTER confirm the code and access Appliance
Setting Program Navigation menu.
4. Once the code is confirmed, you can begin to set the Appliance Settings. Use the arrow keys to navigate. To change a setting, press
ENTER. Appliance settings can be increased by pressing
▲ and decreased by pressing ▼ on the display. Once a new value has been
selected, press ENTER to store the new value.
5. The first screen is the “Central Heating” value. Enter the value for your designed
hydronic heating supply temperature. The factory default is 140
o
F. NOTE: Values are
determined based on program settings.
6. After you have entered and stored the “Central Heating” value, press  once. The
second screen adjusts the heating system “Heating Delta T” value. The factory default
is 20
o
F.
7. After you have entered and stored the “Heating Delta T” value, press  once. The third screen adjusts the “DHW Set Point”. Adjust
the value to the desired Domestic Hot Water temperature. The factory default is
119
o F. IMPORTANT NOTE: This value sets the tank temperature when the appliance
is in warm weather shutdown. A mixing valve must be properly installed and adjusted
to a proper outlet value for safe operation.
8. After you have entered and stored the “DHW Set Point” value, press RESET to return to the home screen on the display. This
completes the essential programming in Appliance Setting Programs. If other values need to be changed in this section, such as the
display time, refer to Control Overview, Part 10.
9. A proper outdoor reset curve should be set to further optimize system performance and efficiency. Figure 29 shows how each
function will affect system performance. The values in Figure 29 show the system default.
