DETERMINING THE AMOUNT OF SENSORS YOU
CAN USE
The EUR–5A has 46 watts of power available for
use between the sensors and contactor. The power
requirement of your contactor will determine the amount
of watts left available for your sensors. After determining
your contactor's power requirement, subtract that from
the 46 available watts, the result will be your available
power for your sensors. You can then take your available
power and use that to determine the number of sensors
you can use.
• Each CIT–1 aerial sensor (at least one is required) uses
2.4 watts of power

AUTOMATIC SNOW/ICE MELTING SYSTEM CONTROL PANEL
MODEL EUR
• Each GIT–1 gutter sensor uses 6 watts of power
• Each SIT–6E pavement sensor uses 6 watts of power
At least one CIT–1 Areal sensor is required for an effective
snow/ice melt system. Make sure your combined sensor
and contactor's power use does not exceed 46 watts.
ENVIRONMENTAL SENSORS
The use of sufficient appropriately-placed environmental
sensors is important for effective and efficient system
operation. An aerial snow sensor can give the system
a head start in protecting against snow or ice buildup,
yielding more consistent protection.
