User Instructions The TPST201 is adjusted very easily by turning the rotary dial on the front of the thermostat to the required temperature setting. To adjust the set temperature, turn the rotary dial to the left to decrease, or right to increase the set temperature. The indicator on the front panel will light when the temperature is below the set value, showing that the thermostat is calling for heat from the boiler. Once the room reaches the set temperature, it will turn off and the TPST201 will stop calling for heat from the boiler. Heat cut off at high temperature When room temperature is over limit at 36°C, all heating outputs will be turned off regardless of the control pattern and delay timers. Valve protection This function can be enabled/disabled by jumper, set jumper to OFF to disable this function or ON to enable this function.
