Patent Pending | Installation Instructions
Glass Sentry can pay for itself within months of installation based upon current costs for electricity. Its compact size and design for easy installation translates into minimum up-front costs and headaches. Unlike other anti-sweat heater controls, Glass Sentry requires no adjustments as conditions in the freezer environment change. Glass Sentry is factory-preset to turn the heater circuit on whenever the coldest points on the door frame drops near the dew point, where condensation begins to form. Once the heater circuit is turned on, it stays on for a minimum of 5 minutes, assuring that the surface temperature of the glass is properly elevated without wasting energy. Some of the Glass Sentry's distinctive features are:
►A 30 amp rating, so one unit can operate up to 16 doors without extra modules and cost. ►Very small and discrete sensors. ►Simple wiring makes Glass Sentry installation a snap.
Patent Pending | Installation Instructions Glass Sentry is an electronic energy-savings invention designed to smartly control the operation of glass door
heaters for walk-in coolers/freezers. Intelligence programmed within the microcontroller of Glass
Sentry efficiently runs the heater circuit enough to keep condensation from occurring on the door frame and glass
without wasting additional energy. By maintaining a temperature on the coldest spots on the door frame just a
few degrees above the dew point, run time on the heater circuit can be reduced by as much as 90%. Glass Sentry

without wasting energy. An adjustment on the end of the unit is set for optimum operation for all conditions, but
can be changed for even better energy-savings depending on the conditions. Referring to Figure 1 below, the
adjustment can be rotated counter-clockwise to decreases the run time on the heater circuit.
