For most users, it is best to only adjust the temperature settings. Internal configurations like heat anticipator settings or calibration are for professionals and altering them can cause performance issues. Always consult your manual before making internal changes.
: Press the SET button once. The green display will show the current target temperature.

Dual 4-digit LEDs (PV = Process Value, SV = Set Value).
If your TT91 has a heat pump, the manual specifies that the terminal must be configured for energizing in cooling (O) or heating (B). For most users, it is best to only
Once your process values are dialed in, activate the LCK parameter function. This blocks unauthorized operators from raising target temperatures or altering critical PID steps.
The unit accepts various sensors, including J and K-type thermocouples and Pt100 RTDs . Ensure your sensor matches the menu setting, or the unit may display "S-E" (Sensor Error). : Press the SET button once
Q: Is the TT91 suitable for indoor use? A: Yes, the TT91 can be used indoors, but ensure proper ventilation to prevent the buildup of fumes.
To access advanced configuration—such as switching from cooling to heating—you need to enter the control settings mode. Press the key for 10 seconds to enter the menu. Use the SET key to navigate through parameters.
