For example, if the appliance is performing Ignitor Warm-up, the display will illustrate IGnt. To enter into this mode, perform the following steps: 1. Press the SELECT push-button on the display board until the LED display reads OPt (Options). 2. To enter into the options mode, press the ENTER/RESET push- button. 3. The display will illustrate Circ. Press the SELECT push-button until the display illustrates StEP. Enter this mode by pressing the ENTER/RESET push-button. 4. The display will illustrate the current appliance operating step. 5. The display will automatically resort to illustrating the outlet temperature. To keep the display in the Display Step Mode, press ENTER/RESET twice in step 3.

In the Main Control Board, a cycle is counted every time the gas valve is energized. To access this number, perform the following procedure: 1. Press the SELECT push-button on the display board until the LED display reads OPt (Options). 2. To enter into the options mode, press the ENTER/RESET push- button. 3. The display will illustrate Circ. Press the SELECT push-button until the display illustrates Count. Enter this mode by pressing the ENTER/RESET push-button. 4. The display will now illustrate the current number of cycles the appliance has cycled through. 5. The display will automatically resort to illustrating the outlet temperature. TANK PROBE INSTALLATION PROCEDURE A tank probe is supplied with each hot water supply boiler. When installed on a tank, the inlet water temperature on the Dia-Scan II will default to the tank temperature. See figures 2 and 3 to add the tank jumper to the control board so that the tank probe is active. A tank probe is NOT supplied with the hydronic heating boilers (GB's). Therefore, a loop or operating thermostat must be provided. This field-supplied operating thermostat should be wired to the BROWN wires at the junction box. The jumper at location J33 on the control board must NOT be on. Refer to figures 2 and 3 for the location of this jumper. Tank Probe Set-Point Adjustment When tank probe is installed in a storage water tank, and the tank probe is used with the WHC1502 system, the controller will monitor and control the temperature of the water at the tank probe location. Setting the tank probe set-point temperature is accomplished through the Display Board control panel. The standard programmable temperature range for the indirect water tank is 110°F to 190°F. The switching differential of the probe is fixed at 5°...
