long enough (a few days) in order to determine the
optimum preheating time.
– Select the optimum start (H7) and give the con-
troller time to adjust to the surrounding conditions.
The room is heating up too slowly.
The floor temperature is limited by the maximum
limiter.
– Deactivate the upper limit (H3).
The room temperature is too hot.
The floor temperature is limited by the minimum
limiter.
– Deactivate the bottom limit (H3).
No entries can be made.
Access protection is enabled.
– Disable access protection (G6).
