WARNING
• Design and install external heater appropriately with considering its protection.
• Inappropriate designing and installation of external heater may cause a fire by emitted heat from
the external heater.
• Fujitsu General Ltd. is not responsible for inappropriate designing or installation of external
heating device.
Auxiliary heater control 1
Operation Condition
Heater on Heater is on as shown in following diagram of heating temperature.
Heater off
• Heater is off as shown in following diagram of heating temperature.
• Other than heating mode
• Error occurred
• Forced thermostat off
• Fan stop protection
• Temperature of heater on (Thon): Adjustable by function number 62 (Operating temperature
switching of external heaters).
• All control temperatures will shift by adjusting “Thon”.

Example: When set temperature (Ts) is 72°F (22°C) (Factory setting),
• and room temperature (Tr) increases above 53.6°F (12°C), signal output is on.
• and room temperature (Tr) increases above 69.8°F (21°C), signal output is off.
• and room temperature (Tr) decreases below 66.2°F (19°C), signal output is on.
• and room temperature (Tr) decreases below 50°F (10°C), signal output is off.
