TC8901 series electronic temperature controllerDetailed product description：

Product Overview

TC-8901 series electronic temperature controller, used for central air conditioning, heating, and cooling systems.
When the TSC series temperature sensor detects a change in the load of the controlled environment, the thermostat uses a proportional integral control algorithm to generate an increasing output signal that can adjust the reversible motor driver.

TC8901 series electronic temperature controller features

Built in or remote variable resistor temperature sensitive element (NTC thermistor).
The set value adjustment model has a transparent interlocking dial cover to prevent unauthorized personnel from improving the set value.
Output function can be converted: forward or reverse (summer/winter) - through local internal jumper or remote centralized switch (SPST contacts can be used as needed).
The proportional band is adjustable.
Backup setting value.
Flexible installation: wall mounted, embedded, disk mounted or concealed in fan coil units, end devices, etc.
