Temperature control relays for lift machine rooms are designed for monitoring the temperature between 5 °C and 40 °C according to standard EN81.
As long as the temperature controlled by the PT100 stays between the two preset thresholds on the front face, the output relays are closed and their yellow LEDs are lit.
When the temperature exceeds one of the preset thresholds on the front face (upper or lower threshold), the preset time delay on the front face (Tt) is activated. The yellow LED corresponding to
