The Alre-it Air Heater Thermostat JTL-2 is a minimum or maximum thermostat for monitoring supply air and controlling fans in ventilation and air conditioning systems. It is type-tested by TÜV according to DIN EN 14597 and suitable for warm air heaters according to DIN 4794.

Sensor Break: In case of sensor damage or breakage, contacts 1 and 4 of the fan open.

Intrinsic Safety/Cooling Protection: The devices are intrinsically safe, meaning that in the event of loss of the sensing medium, such as due to sensor breakage, the burner is shut down. Since negative temperatures can cause the same effect through volume reduction of the sensing medium, the devices are adjusted using the cooling screw so that they only shut down the burner at temperatures below 15 °C. Re-enabling can only be done manually at temperatures above approximately 5 °C using the manual reset button.

Overheating Protection: The device protects against uncontrolled overheating, caused for example by heat accumulation or gradual loss of capillary fill due to invisible damage to the sensor or capillary tube. When a temperature of 220 °C is reached, the safety solder in the sensor melts, and the device shuts down the burner for safety due to loss of the filling medium. The burner cannot be restarted. The device then becomes unusable and serves as evidence of the existing overtemperature of at least 220 °C.
