[. . . ] SINGLE- AND DUAL-STAGE INDUSTRIAL ROOM THERMOSTATS SPECIFICATION DATA AND MOUNTING INSTRUCTIONS T6120A, B GENERAL The T6120A and B Single- and Dual-Stage Industrial Room Thermostats are designed for measuring, monitoring, and controlling temperatures in heating and cooling systems. These thermostats are suitable for the following areas of applications: · commercial buildings, · storage rooms, · garages, · machine rooms, · factories, · greenhouses, and · agricultural installations. FEATURES · · · · Liquid-filled stainless steel or copper (T6120A1005, only) bulb. Easy installation and wiring connection. [. . . ] When the temperature rises, the contact will open (see Fig. 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). 2 3 1 red blue white T T Fig. Wiring T6120A1013/1021/1039 and T6120B1003 Adjusting the Hysteresis (T6120A1013/A1021, only) PG 13. 5 105 70 52 90 108 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. The dial settings are numbered from "2" (corresponding to the min. setting of 2 K) to "15" (corresponding to the max.
