Electronic Controller
Principles
The Electronic Controller displays the temperature of the water in the water jacket.
1) At its low setting it will turn the combustion air blower(s) on , re-igniting the
fire.
2) At its high setting it will turn the combustion air blower(s) off , extinguishing
the fire.
3) The difference between the highest temperature of the water and the
lowest temperature of the water is factory set at 20 degrees Fahrenheit.
Operation
The factory settings on this aquastat should not be changed; changing the factory
settings will void the warranty and certifications.
Maintenance
Keep the face of the display clean by cleaning periodically with glass cleaner.
Removal and Replacement
1) Turn off the main power supply to the HEATMOR™.
2) Remove the 6 screws from the inside front panel that hold the Electronics.
3) Pull the panel away from the housing to obtain clearance to work on the Electronic Controller
from the back.
4) Disconnect and label or draw a diagram of each wire connection on the Electronic Controller.
5) Replace the controller and reverse the steps above for re-installation.
nOte: The temperature reading on the display may not coincide exactly with the temperature of the water
leaving the HEATMOR™ or the temperature of the water arriving into the building being heated. There may
also be small variances between the temperature reading on the display at the front of the HEATMOR™ and
the high limit aquastat of the HEATMOR™.
These variances result from:
1) The Electronic Controller is reading the temperature of the water at the top left of the water
jacket, at the side of the HEATMOR™. The hot supply water is taken from the bottom of the water
jacket at the front of the HEATMOR™.
2) The high limit aquastat is reading the temperature from the top right of the water jacket, at the side of
the HEATMOR™.
3) Until the water is thoroughly mixed, whether or not the unit is firing, there will be variances between
the different instruments.

IN A NORMAL OPERATING MODE, SMALL VARIANCES IN READINGS AND
CALIBRATIONS WILL NOT AFFECT THE END RESULTS OF THE TOTAL SYSTEM.
