If desired, a second input may be used to monitor the internal IRSM ambient temperature. Consult ANAFAZE for
more information.

3.3.11 SCALING AND CALIBRATION

The ANAFAZE 12LS includes a scaling provision to convert analog inputs into engineering units. Section 4.5.2.3
describes how to set the automatic scaling.

3.4 CONTROL OUTPUTS

+-----------------------------------------------------+
¦ WARNING! -- GROUND LOOP POTENTIAL ¦
+-----------------------------------------------------¦
¦ The ground of every control output is connected to ¦
¦the ANAFAZE 12LS logic ground. Use caution when ¦
¦connecting external devices that may have their low ¦
¦ side at voltage other than controller ground, since ¦
¦ potential ground loops can be created. Use isolated ¦
¦ relays or the isolated control device inputs if ¦
¦ possible grounding problems are expected. ¦
+-----------------------------------------------------+

The ANAFAZE 12LS includes two sets of control outputs for each loop. These are provided on the 50 pin ribbon
cable connector and are set for heat/cool whether or not they will be used for each application.

1. Each output may be individually programmed as a different type (on/off, CTP, or DZC.).

2. Each output can be individually programmed to be direct or reverse acting [both outputs can be the same].

3. There may be a deadband programmed for heat/cool, and within that deadband both outputs will be off.
