T6120A,B SINGLEAND DUAL-STAGE INDUSTRIAL ROOM THERMOSTATS
T6120A1005
Function and Wiring
To control a heating unit, connect terminals 2 and 3 of the thermostat to the heating unit. When the temperature rises, the contact will open (see Fig. 1).
To control a cooling unit, connect terminals 1 and 2 of the thermostat to the cooling unit. When the temperature drops, the contact will open (see Fig. 1).

T6120A1013/A1021/A1039
Function and Wiring
To control a heating unit, connect the red terminal ("COMMON") and the blue terminal ("NORM OPEN") of the thermostat to the heating unit. When the temperature rises, the contact will open (see Fig. 3).
To control a cooling unit, connect the red terminal ("COMMON") and white terminal ("NORM CLOSED") of the thermostat to the cooling unit. When the temperature drops, the contact will open (see Fig. 3).

Adjusting the Hysteresis (T6120A1013/A1021, only)
In the case of the T6120A1013/A1021 Single-Stage Thermostats, it is possible to adjust the hysteresis to a value of between 2 K (factory setting) and 15 K. This can be done as follows:
Pull off the adjustment knob, unscrew the two fastening screws, and remove the housing cover. The hysteresis adjustment dial is now visible (see Fig. 4). The dial settings are numbered from "2" (corresponding to the min. setting of 2 K) to "15" (corresponding to the max. setting of 15 K).
