Why is the hot water temperature too high in my CALEFFI Heating System?
- D
  David WolfeAug 25, 2025
  If the hot water temperature is too high, first decrease the domestic water cycle temperature set point. Restore correct connection if DHW temperature probe cable is inverted with heating probe. If the primary circuit has an excessive flow rate due to DPCV valve malfunction or if Antilegionella cycle is in progress, contact person in charge of system. For other causes like a faulty modulating valve actuator, valve obturator blocked in intermediate or open position, electronic regulator not working, it is best to call qualified personnel to have it replaced.

What to do if hot water flow rate is insufficient in CALEFFI Heating System?
- J
  Jessica CampbellAug 29, 2025
  If the hot water flow rate is insufficient, open the valves if possible domestic water system shut-off valves are partially closed. For other causes like HIU strainer clogged, insufficient pressure in centralised domestic water circuit, it is best to call qualified personnel to have it serviced.

What to do if hot water flow rate is zero in my CALEFFI Heating System?

  Richard ThomasSep 3, 2025
  If the hot water flow rate is zero, open the valves if possible domestic water system shut-off valves are closed. For other causes like no cold water in centralised domestic circuit, HIU strainer completely clogged, exchanger completely blocked, it is best to call qualified personnel to have it serviced.

What to do if domestic hot water is not heated in my CALEFFI Heating System?
- A
  Anthony CombsNov 8, 2025
  If the domestic hot water is not heated, several issues could be the cause. First, check if the primary circuit shut-off valves are closed and open them if necessary. Ensure the modulating valve actuator is correctly connected to the valve body; reconnect it if disconnected. Also, verify that the DHW temperature probe cable isn't inverted with the heating probe and restore the correct connection if it is. Other potential causes include air in the system (vent the system), a disconnected DHW temperature probe (reconnect it), a disconnected DHW priority flow meter (reconnect it), or disabled DHW production (enable it via the HIU interface). Check for cut off electric supply and restore it. If it is not the case, it could be incorrect wiring or no credit - check electrical connections and top...

Why is the room not reaching the desired temperature in my CALEFFI Heating System?

  Laura WiseNov 13, 2025
  If the room isn't reaching the desired temperature, consider these potential causes. First, ensure the heating cycle temperature set point isn't too low and increase it if needed. Check the programming of the chrono-thermostat to make sure the temperature settings and time are correct. Also, verify that the modulating valve actuator connector is connected, reconnect it if disconnected and that pump cable is connected, restore connection if disconnected. Possible system shut-off valves/terminals closed - open the valves. Additionally, check if the DHW temperature probe cable is inverted with the heating probe and restore the correct connection if it is. Vent the system to remove any air. Check for cut off electric supply and restore it. Restore system pressure if heating circuit pressure is...

What to do if the water is hot but does not reach the desired temperature in my CALEFFI Heating System?

  If the water is hot but not reaching the desired temperature, check the domestic water cycle temperature set point and increase it if it's too low. If primary return temperature limitation intervention occurs, change the return temperature set point or disable the function. Restore correct connection if DHW temperature probe cable is inverted with heating probe. Decrease demand if there is excessive demand for DHW. If the centralised system temperature is insufficient, the primary circuit flow rate is insufficient, or the primary flow rate limit is too low, contact the person in charge of the system. For other causes like a clogged primary circuit strainer of the HIU, partly clogged exchanger, faulty modulating valve actuator, electronic controller not working, it is best to call qualified...
