Specifications of the signal output performance are as shown as follows:
Example: When set temperature (Ts) is set at 22°C;
• And room temperature (Tr) increase above 12°C, signal output is on.
• And Tr increase above 21°C, signal output is off.
• And Tr decrease below 19°C, signal output is on.
• And Tr decrease below 10°C, signal output is off.
