details, refer to function number 71.
Example: When set temperature (Ts) is 22°C (Factory setting),
– and room temperature (Tr) increases above 12°C, signal output is on.
– and room temperature (Tr) increases above 21°C, signal output is off.
– and room temperature (Tr) decreases below 19°C, signal output is on.
– and room temperature (Tr) decreases below 10°C, signal output is off.
