Insufficient heat in heating system — Possibly due to Night Setback

What does Insufficient Heat mean?

If your heating system is not providing adequate heat, one possible cause is the 'Night Setback' function being active. This feature automatically reduces pump activity during certain periods to save energy.

• Night setback function is currently enabled in Grundfos GO
• Incorrect pump setting for the system's current heat demand
• System demand exceeding the pump's current operating capacity
