The following adjustments must be made before power is applied to the system:
1. System selection switches.
2. Burner cycles per hour (3 to 9), typical setting: 6.
3. Domestic hot water (35 up to 100°C), typical setting: 55°C.
Note: The switch A–B should be in position A for the domestic hot water to be off when the system is controlling at the Economy level. The switch should be in position B for the domestic hot water to be continuously serviced.
