Diagram of connection of one ACR 1000-1500-2000 E curtain (electric heater)
to the COMFORT panel
In the summer time, it is possible to switch off the electric heater and use the ACR E curtain as a cold curtain (i.e., fan only, electric
heater does not work). In this case, a simple power cut-off installation (shown in the dashed diagram below) must be made.
The installation consist in inserting any on/off switch (labelled as “G”) into the control circuit between terminal 3 on Comfort Panel and
Terminal 2 in the ACR curtain. The on/off switch itself should be installed in a place suitable for the curtain user.
Warning! The Comfort Panel thermostat must be set to max. The on/off switch and the wires to the switch are not included in the
scope of delivery
Connection of ACR curtains based on BMS communication module
• The BMS module for ACR curtains allows to monitoring the operation of the curtain (EMERGENCY/FAILURE signal) and switches
the curtain on/off from the master BMS system.
• With the use of digital signals 0/1 (potential free contact), the BMS can work with any BMS master protocol without need to convert
the signal
