If the Carel Controller displays 'E0 FLASHING', indicating a control sensor error, it could be due to a non-working sensor because of signal interruption, a short-circuit, or the sensor not being compatible with the equipment. Also, the parameter /0 might not correspond to the unit's hardware setup. Check parameter /0 to ensure it corresponds to the unit's hardware setup.
How to fix Carel IRDRC E1 FLASHING evaporator sensor error?
If the Carel Controller displays 'E1 FLASHING', which indicates an evaporator sensor error, it may be caused by a sensor not working due to signal interruption, a short circuit, or the sensor being incompatible with the equipment. It may also be that parameter /0 does not correspond to the unit's hardware setup. To resolve this, check parameter /0 to ensure it corresponds to the unit's hardware setup.
Why is my Carel Controller HI FLASHING high temperature alarm?
If the Carel Controller shows 'HI FLASHING', indicating a high-temperature alarm, it means the sensor has registered a temperature higher than the set value, exceeding the parameter AH. To address this, check the parameters AH, Ad, and A0.
What does it mean when my Carel IRDRC shows LO FLASHING low temperature alarm?
When the Carel Controller displays 'LO FLASHING', signaling a low temperature alarm, it means the sensor has registered a temperature lower than the set value, falling below the parameter AL. To resolve this, check the parameters AL, Ad, and A0.
What to do if Carel Controller Ed FLASHING defrost stopped due to expiry of the maximum time?
If the Carel Controller displays 'Ed FLASHING', indicating that the last defrost stopped because the maximum time expired, check parameters dt, dP, and d4. Also, check the effectiveness of the defrost. If the next defrost ends on temperature, the signal will disappear automatically.
Why Carel IRDRC Controller temperature is outside set limits but no alarm is signalled?
If the temperature is outside the set limits, but no alarm is signaled on the Carel Controller, it may be due to the alarm delay operating. To solve this, check Ad.
How to troubleshoot Carel IRDRC when compressor will not start and compressor LED is flashing?
If the compressor won't start and the compressor LED is flashing on the Carel Controller, it could be due to the compressor delay operating. To address this, review parameters c0, c1, and c2.
Why is Carel IRDRC Controller defrost not activated and defrost LED is off?
If the defrost is not activated and the defrost LED is off on the Carel Controller, and if H1=0, it could be because the defrost cycle is too short (dp) or the interval between defrosting dl=0. To solve this, check parameters dP and dl.
What to do if manual defrost is not activated and defrost LED is flashing on Carel Controller?
If the manual defrost is not activated and the defrost LED is flashing on the Carel Controller, it might be due to compressor protection delays operating. To resolve this, check parameter d9 (select d9=1, see instructions).
Why is Carel IRDRC signalling AL or Ad alarm without being active?
If the Carel Controller signals an AL or Ad alarm (Multi-function input) without it actually being active, it may be because the multi-function input generates an alarm as power goes on. To fix this, check the connection of the input and ensure it is off during normal operation.
