Wallas Cooling Thermostat T1

To ensure your Wallas heater cools down safely after shutdown: The T1 post-cooling thermostat monitors the temperature after heating operation and ensures that the cooling process runs correctly. A small, but safety-critical component that protects the lifespan of your heater.

Tip: Before installation, check whether the thermostat is actually defective – a Wallas service technician can narrow down the cause of the fault with a simple continuity test.
