4.4 APPLIANCE CONTROLS
NOTICE
The appliance frost protection is active in all the boiler modes.
The control panel functions can be used to vary the temperature
of the water that circulates around your heating system and the
water that flows from your hot water taps.
The heating temperature range can be adjusted between 68°F
- 113°F (20°C - 45°C) (for low temperature) or 68°F - 180°F (20°C
- 82°C) (for high temperature) this range is configured by your
installer and the default is the high temperature range. The hot
water temperature range can be adjusted between 99°F -
140°F (37°C - 60°C).
NOTICE:
the actual delivery temperature is also conditional upon
the incoming water temperature and the actual flow-rate at the
outlet.
Refer to the section 4.12 for fault indicator and boiler status.
