– Temperature of heater on (Thon): Adjustable by function number 62 (Operating temperature
switching of external heaters).
– All control temperatures will shift by adjusting "Thon".

A
*: When room temperature stays in this zone for a specific time, auxiliary heater is turned on. For
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.
