Double Electrical Outlets at Rear
Principles
To provide a live source of 115V power to power pumps, trouble lights, etc.
Maintenance
• Do not overload the circuit.
• Keep the outlets clean.
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 40 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 screws from the outside corner panel that holds the Electronic
Controller.
3) Pull the corner panel away from the housing to obtain clearance to work on the Electronic Controller
from the back.
4) Remove the two screws that hold the Electronic Controller mountingbox.
5) Disconnect and label or draw a diagram of each wire connection on the Electronic Controller.
6) Replace the controller and reverse the steps above for re-installation.
nOte:
Different makes and models of furnaces may have different controllers. These controllers will NOT be
interchangeable. Replace with the correct unit from your dealer.
nOte:
The temperature reading on the display may not coincide exactly with the temperature of the water
leaving the back of 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 on the back of the HEATMOR™.
nOte:
200 SSRII Controller will alarm if your HEATMOR™ has low water, it will also cut power to the blower
fan.
These variances result from:
1) The Electronic Controller is reading the temperature of the water at the middle of the water jacket, at
the rear of the HEATMOR™. The hot supply water is taken from the bottom of the water jacket at the
rear of the HEATMOR™.

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