1 Overview
The Control Link ACC Anti-Condensate
Controller System is a controller for anti-sweat
heaters inside glass door cases and can be used either
as a stand-alone device or networked with the E2
controller over the MODBUS network. There are two
available models of the Control Link ACC:
• UL Listed version 7A/10A ( P/N 815-6100 )
• UL Recognized version 18A/26A/30A

( P/N 815-6105 ) - requires an additional heat sink
The Control Link ACC varies the anti-sweat
heaters based on the temperature of the door frame
and surrounding dewpoint, providing the most
efficient control possible in order to maximize energy
savings.
2 Components
2.1. Control Link ACC

(P/Ns 815-6100 and
815-6105)
The Control Link ACC ( Figure 2-1 ) handles all
aspects of anti-sweat heater control and uses solid-
state switching to control the heaters. The on-board
processor calculates the required heater ON time
based on the dewpoint and door frame temperature
readings, and controls an on-board Triac to activate
and deactivate the heaters.
The controller is designed to mount in the mullion
between glass doors or in any other suitable electrical
enclosure, such as a raceway or on the top of the case.
The door frame temperature sensor and dewpoint
sensor are mounted remotely and connect to this
controller with cable harnesses.
Four LEDs can be viewed on the front of the
plastic enclosure. They indicate the general status,
heater ON, MODBUS network transmit (TX), and
MODBUS network receive (RX).
