This user guide covers the following thermostat models:
• TH131 A/F/AF
• TH133 A/F/AF
The TH131 model is designed for residential applications, whereas
the TH133 model is designed for public areas as its controls are hidden and thus protected against unauthorized access. Both models
can be configured for the following applications:
noitacilppAepyT
A Controls the ambient (room) temperature
F Controls the floor temperature
AF Controls the ambient temperature and limits the floor temperature
Position the switch, on the back of the control module, according to
your application.
3.2 Minimum and Maximum Limits (TH131 only)
Use the two potentiometers on the
back of the control module to set
the minimum and maximum temperature limits. Depending on your
application, the potentiometers
limit the following temperature:
ambient temperature (A)
floor temperature (F or AF)
Use a flat-tip screwdriver to rotate
the potentiometers until the notch
