Low room temperature — Check heating settings and room thermostats

What does Low room temperature mean?

If the room temperature is consistently low, it may be due to incorrect heating control settings, thermostats being turned down, or issues with the heating curve.

• Closed thermostats in several rooms
• Control module in incorrect operating mode
• Low set value on automatic heating control
• Heating curve requires adjustment
