DASH Controller
The Door Anti Sweat Heater (DASH) controller is
designed for conservation of energy by reducing power
consumption of the glass door frame assemblies.
The control consists of three components: a control
module located in the raceway, a combination tempera-
ture and %RH sensor mounted in the door mullion
and an interconnecting cable. All three components are
factory installed in the frame assembly.
The glass anti-condensate heaters are under the control
of a microprocessor, which eliminates operator
adjustment and guarantees maximum energy savings.
The sensor detects product loading as well as peak
shopping to optimize clearing time.
The control switches a maximum load of 5 amps which
allows the control to be applied to one to five door
frame assemblies. Each is equipped with its own con-
trol/sensor.
