Amtrol BoilerMate Top Down - Manual (Page 19)

The Smart Control™ features an error code designed to alert the user to the presence of water on the floor. This is useful to
warn of a leaking boiler, water heater, etc., or to alert the owner to a leak in the basement. If equipped with the optional water
sensor, follow the installation instructions below:
Water
Sensor
Plug
1. If the sensor will be used to detect a water heater leak, the proper placement is in a drip pan as required in the warning
section of this manual. This will both protect the surrounding surfaces from water damage and provide sufficient water depth
to activate the alarm. The sensor will function with either side placed toward the floor.
2. If the sensor will be used to detect another potential leak source, such as basement flooding, the sensor must be placed
on a flat section of floor in an area where water will first collect. If the level cannot reach 1/32”, the alarm feature may not
function. Do not place in a high-traffic area where the sensor could be stepped on or moved. The sensor will function with
either side placed toward the floor.
3. After placing the sensor in the appropriate location, plug the water sensor connector into the Smart Control™.
4. Upon wiring the Smart Control™, test the sensor by either immersing it in water or inserting a coin between the two
electrodes. The Smart Control should display Er4 and sound an alarm. The error and alarm should disappear when the sensor
is dried or the coin is removed. Perform this test during the annual inspection of the BoilerMate
® , or more frequently if installed
in an area known to flood.
5. This sensor should not be the primary means of leak detection.
