E.ADJUSTING THE TEMPERATURE ON THE MUNCHKIN DISPLAY:
1.Before you can change the temperature from the factory setting of 180 degrees. You must make sure that none of the thermostats are calling for heat. The Munchkin controller will not memorize a program setting while in a heating cycle. To adjust the temperature to the Munchkin simply press in the S3/Program key for three seconds until you see a flashing (C) then an alternate value of (180). This number is the factory set point of the unit, which is 180 degrees. To change the temperature, simply push either the S1/– or S2/+ on the display. The S1/– button will decrease the tempera- ture while the S2/+ will increase the temperature of the Munchkin. The temperature of the Munchkin can be set as low as 50 Degrees and as high 203 Degrees. These ranges are your maxi- mum and minimum ranges of the Munchkin. In addition to changing the temperature you are also allowed to change three more settings in this model (1. Munchkin differential – 2. Indirect setting (Vision System Only) – 3. Celsius to Farenheit measurement. Simply press in the S3/Program key to get to next value, the Munchkin differential setting will appear in the display ch and alternating value of 30. This allows the installer to adjust the activation of the burner based on the differential temperature setting of the Munchkin. The burner will not start until the outlet water temperature reaches a temperature that is equal to the temperature setting for the Munchkin, minus the differ- ential EX: The Munchkin is set to heat at 180° F degrees and the differential is set at 20° F. The burn- er will not start until the outlet temperature of the system falls below 159° F degrees (180° – 20° F = 160° F). To adjust, press either S1/– (Decrease Value) or S2/+ (Increase Value) Ranges 5° F to 30° F. Press the S3/Program key again and you will see the Indirect Setting de and an alternative value of 119 (Vision Systems Only) To adjust, press either S1/– (Decrease Value) or S2/+ (Increase Value).
The final adjustment in this mode is the Farenheit to Celcius measurement. Press the S3/Program key again and you will see t and alternating value of F. To change value press the S1/– or S2/+ to choose the correct measurement.
F. STATUS MENU
Installers are also able to check the current status of the Munchkin parameters by pressing S4/RESET key for 3 seconds. Once activated, the display will show d1 alternating value of the actual outlet tem- perature. Actual values are displayed for each function. To view the next value simply press the S/4 key to go to the next displayed value. Listed below are the values which can be displayed. These val- ues cannot be changed. To exit this menu, simply press S3/Program key to resume normal operation.
