11351 GIT-1 Gutter Deicing Sensor and Clamps

23864 Moisture Sensor Cup

GUTTERS

1. Where it will detect initial snow and ice, position or lay sensor 

within 1/4”(6.4mm) of the gutter bottom. For applications

not using the optional Moisture Sensor Cup (Figure 2; see its 

manual, p/n 23973), ensure moisture sensing grid (Figure 3) faces 

downstream (ambient air temperature sensor facing upstream) to 

avoid collecting debris against the grid. Avoid

locations where puddling may occur. Sensor may be fastened to the 

fascia with the included mounting clamps, using #8 or #10 screws or 

bolts and standoffs as required (not furnished).

DOWNSPOUTS

2. Sensor may be mounted in downspout or on roof edges, 

positioned to ensure snow sensing. However, be certain to 

protect it from falling or shifting snow and ice masses. Fold cable 

back parallel to sensor body and secure with mounting clamps 

(or weatherproof tape). Suspend sensor in downspout with 

moisture sensing grid facing up (ambient temperature sensor 

facing down) as close to the downspout opening as possible.

3. Up to six (6) GIT-1 sensors may be wired in parallel to one 

control panel; any sensor will activate deicing. System will remain 

activated until ALL sensors are clear of ice, snow and water.

4. Debris collected against the sensor grid will degrade sensor 

performance. Locate sensor to avoid falling and blowing debris. 

Clean gutters before winter season to assure best operation.

5. To prevent corrosion during off-season months, maintain the 

power to the sensor to allow evaporation of moisture from the 

sensing grid.
