Do you have a question about the ERC 112D VSC and is the answer not in the manual?
Questions and answers
What does 4.5.6 connect to ?
Mostrador do controlar, fica travado , não mostra a temperatura real
The Danfoss ERC 112D VSC display may be stuck and not showing the actual temperature due to the "rLt" (Display Range Limit) parameter being set to restrict the displayed temperature to the cut-in / cut-out limits instead of the actual temperature. If "rLt" is set to "yes," it will not show the real temperature. To display the actual temperature, "rLt" must be set to "nO".
Additionally, the display might update slowly if a "ddL" (Display Delay) is set, causing a delay in showing temperature changes. Also, temperature updates can be blocked during fan OFF periods and only resume after the fan has been running for a while.

como entrar no parâmetro "rLt" (Limite da Faixa de Exibição) e fazer alteração?
To access and change the "rLt" (Display Range Limit) parameter on the Danfoss ERC 112D VSC, follow these steps:
1. Enter the parameter configuration mode.
2. Navigate through the parameter list to find "rLt".
3. Select "rLt" to view or change its value.
4. Set the value to “nO” to display the actual temperature or “yes” to restrict the display to cut-in/cut-out limits.
5. Confirm the selection to save the change.
The default setting is “nO”.
