If ready-for-laying heating is activated, the current phase appears:
1 = Initialisation
2 = Rising-temperature phase
3 = Temperature-maintenance phase,
4 = Falling-temperature phase
Once the floor drying has been successfully completed, the numerical value
of 9 appears. If the floor drying function was disrupted (due to a sensor
failure or a long-lasting high control offset etc.), value 8 is shown instead of 9
to signal the fault. In the case of functional heating in accordance with EN
1264 Part 4, control offset of more than 3K for more than 10 minutes is
considered to be too high. In the case of ready-for-laying heating, offset of
more than 5K for more than 30 minutes are considered to be excessive.
Values 8 and 9 can only be read. They cannot be assigned to the SERVice
parameter.
After floor drying has been completed, the EQJW 145 operates according to
the switch setting and the switching commands. Floor drying can be aborted
by setting parameter SP60 to 0. If the power supply fails, floor drying ceases.
When power is restored, the drying procedure restarts automatically.
